This guide demonstrates how to lock cells in Excel worksheets to protect formulas or other data from being changed, while allowing selected cells to remain unlocked. This is useful to prevent accidental changes to the worksheet and to enhance navigability by allowing users to select only the modifiable cells. The information in this guide was tested on a Windows XP system using Microsoft Excel ver. 2003. The steps in this guide should be similar for other versions of Excel. An example worksheet provided for this guide is provided here.

Steps to Protect Excel Worksheets

1. Use the Control or Shift key to select individual cells that are to remain unprotected and modifiable by the user. The screenshot below shows the selected cells in grey. All unselected cells will be protected.

Useful information from Tinyapps.org that shows how to retrieve and embed cover art into audio files with MP3Tag and the command-line application DisCoverArt. The blog post is reproduced in its entirety below:

Batch download and embed album cover art #

If you have a huge MP3 collection and just want to batch download and embed cover art without verifying each cover individually (and iTunes’ “Get Album Artwork” is insufficient):

  1. Download and install Mp3tag
  2. Download DisCoverArt and unzip contents to the Mp3tag program directory (e.g., C:\Program Files (x86)\Mp3tag)
  3. Open an elevated command prompt and cd to the Mp3tag program directory
  4. Run regsvr32 custommsgbox.dll and click OK when the success dialog appears
  5. Open Mp3tag
  6. File > Add directory… > navigate to your music folder > Select Folder
  7. Create a new tool:
    1. Tools > Options > Tools
    2. Click the New (yellow star) button
    3. Name: DisCoverArt Google 300×300 Artist+Title NoQuotes
    4. Path: Browse to the Mp3tag program directory and select DisCoverArt.exe
    5. Parameter: “%artist%” “%title%” -discomusic.com 0 1 300 300 jpg 1 1
    6. Check “for all selected files” > OK > OK
  8. Create a new action:
    1. Actions > Actions (you need to select at least one song in the main interface for this menu item to be available)
    2. Click the New (yellow star) button
    3. Name of action group: Save Coverart
    4. Click OK > click the New button again
    5. Select action type: Import Cover From File > OK
    6. Format string for image filename: %artist% – %title%.jpg
    7. Import cover as: Front Cover
    8. Check “Delete existing cover art” > OK > OK > Close
  9. Right click on column header > Customize columns… > check “Cover” > click “Move up” until it is at or near the top of the list
  10. Click the Cover column to sort
  11. Select all files without an entry in the Cover column (the author recommends selecting no more than 300 at a time to avoid problems)
  12. Right click on highlighted files and click Tools > DisCoverArt Google 300×300 Artist+Title NoQuotes
  13. Wait for all console windows to close
  14. Actions > Actions (Quick) > “Import cover from file” > OK
  15. Format string for image filename: %artist% – %title%.jpg
  16. Import cover as: Front Cover
  17. Check “Delete existing cover art” > OK > OK
  18. Close Mp3tag
  19. Getting the artwork to show up in iTunes:
    1. Open iTunes and click “Albums”
    2. Edit > Select All > Right click > click “Uncheck Selection” (album covers will appear)
    3. Edit > Select All > Right click > “Check Selection”

Another option is to download cover art with Album Art Downloader and embed with Mp3tag:

  1. Download and run Album Art Downloader
  2. File > New > File Browser…
  3. Enter path to music directory under “Search for audio files in:”
  4. Click Search
  5. Click “Select all albums with missing artwork”
  6. Click “Get Artwork for Selection…”
  7. Click “Automatically download and save results for the remaining queued searches”
  8. Click “Download and save results automatically”
  9. Click “Start”
  10. When the process is complete, embed the album art with Mp3tag by starting with step 14 above. The only change is in step 15, where you’ll need to use Folder.jpg as the format string.

screenshot of main menuThis guide provides everything needed to create a customizable multi-boot USB flash drive in Windows with high resolution menus and customized splash screens. It provides a framework for creating a basic but functional multi-boot flash drive using Syslinux 6.xx as the primary bootloader. Basic menu configuration files and splash screen examples are provided. Experienced users shouldn’t find it difficult to follow this guide to create a ready-to-use bootable flash drive that can be customized to their needs. Users should already have some familiarity with Syslinux, installing Linux distros, and with formatting and partitioning flash drives.

For the sake of simplicity, this guide is limited to setting up Syslinux for a single partition using the BIOS modules. The instructions were tested and verified on a system running Windows XP SP3 and using Syslinux 6.02.screenshot of menu3 This guide is essentially a more up-to-date version and combination of two previous posts, Create a Multiboot Multipartition USB with Syslinux and Grub4Dos and Create Custom Grub4Dos, GRUB and Syslinux Compatible Splash Images.

Syslinux 6.xx

Syslinux provides two menu systems, the Simple Menu System and the Advanced Menu System. The advanced system must be compiled while the simple system includes the ready-to-use vesamenu.c32 and menu.c32 modules. This guide uses the vesamenu.c32 module.

Splash Screen Resolutions

Syslinux 6.xx can use splash screens in the .png or jpg formats at resolutions from 640×480 up to whatever is supported by the system. If the flash drive is going to be used on multiple systems, it would be best to use a typical resolution such as 800×600 that would work across most systems.

Modules

Since version 5.xx, modules are no longer stand alone and need additional libraries to work. A description of the changes can be found on the Syslinux Wiki at http://www.syslinux.org/wiki/index.php/Library_modules. In most cases, Syslinux will alert you of any additional libraries required when you try to use them.

(U)EFI (Unified/Extensible Firmware Interface)

Although there has been a lot of hype about (U)EFI (Unified/Extensible Firmware Interface) in general and support for (U)EFI began with Syslinux 6.xx, the (U)EFI modules are still fairly new, have a number of unresolved issues, and are not widely used at this time. UEFI in Syslinux is buggy and has problems on both Windows and Linux. Arch Linux describes some of the more relevant ones at http://wiki.archlinux.org/index.php/syslinux#Limitations_of_UEFI_Syslinux. Some of the issues with UEFI are:

  • UEFI Syslinux does not support chainloading other EFI applications like UEFI Shell or Windows Boot Manager.
  • UEFI Syslinux does not boot in Virtual Machines like QEMU/OVMF or VirtualBox or VMware and in some UEFI emulation environments like DUET.
  • Memdisk is not available for UEFI.
  • UEFI Syslinux application syslinux.efi cannot be signed by sbsign (from sbsigntool) for UEFI Secure Boot.
  • Using TAB to edit kernel parameters in UEFI Syslinux menu leads to garbaged display (text on top of one-another).

Other Syslinux issues/limitations:

  • Using Syslinux 6.02 on BTRFS volumes corrupts the superblock.
  • Syslinux cannot access files from partitions other than its own.
  • Using the memdisk module to boot most ISOs is often difficult or impossible.

Syslinux.org has admitted to these limitations and has often recommended other bootloaders such as GRUB, Grub4Dos, or Plop Boot Manager to compliment Syslinux. In spite of this, Syslinux remains one of the most functional and popular bootloaders not only for flash drives, but for other bootable devices like CDs, for most operating systems, and for chainloading partitions and hard drives. It’s very flexible and is an excellent choice as the primary bootloader for most situations. Adding another bootloader such as Grub4Dos however, greatly enhances the flash drive’s booting options.

Creating a Multi-boot Flash Drive steps:

  1. Format the flash drive
  2. Install Syslinux 6.xx
  3. Install modules and files
  4. Install or create splash screens
  5. Customize menu configuration files (optional)

1. Format the Flash Drive

Format the flash drive with FAT16 or FAT32.

2.  Install Syslinux 6.xx

Download and unzip the latest .zip version of Syslinux 6.xx from Kernel.org. The file size should be about 12mB before unzipping. Open a cmd window and cd to C:\syslinux-6.xx\bios\win32. Type the following to install Syslinux to the flash drive where x is your flash drive:

syslinux.exe -sfma x:

This installs ldlinux.c32 and ldlinux.sys to the flash drive.

3. Install Modules and Files

Modules

Look for and copy the BIOS versions of the modules shown in the directory tree for the root of the flash drive. An easy way to locate the modules is to use something like AgentRansack. Modules have a .c32 extension (except memdisk) and are located in various folders in the C:\syslinux-6.xx\bios\com32 directory. Place all of the modules in the root directory.

Configuration Files

The help text, menu.cfg, syslinux.cfg and other configuration files required can be downloaded from the configfiles download link below.  Download and extract them to the root of the flash drive.

Download the latest version of Grub4Dos from grub4dos-chenall. Extract the grub.exe and menu.lst files to the root of the flash drive.

4. Install or Create Splash Screens

Install ready-made Splash Screens

To get started, splash screens tested to work with the configuration files are provided below. Just unzip them to the splashimages folder. After installing the splash screen images, the flash drive is ready to test or use.

Link for the splash screens: splashscreens

Nine (9) splashscreen files are provided. Download them as an album and extract to the splashimages folder. Slightly change the filenames by removing the number and dash so the filenames match those used in the menu configuration files.

The correct splashscreen filenames are:

  1. cave_800x600_14.png
  2. fallleaf_800x600_14.png
  3. grassyhill_800x600_14.jpg
  4. mist_800x600_14.png
  5. nightlight_800x600_24.jpg
  6. ny_800x600_14.jpg
  7. road_800x600_14.png
  8. Spruce_800x600_14.png
  9. winter_800x600_14.jpg.

The link below displays a directory of what the flash drive contents should look like at this point:

indexFlashDrive

Create and Install Customized Splash Screens (optional)

To create your own menu graphics, use the batch file below or another graphics program to create .png or .jpg format splash screens from your image files. Since the menus are already configured with light text, you may want to use a dark color to start off with. Generally, 14 colors works nearly every time and renders more quickly.

The batch file below is configured to use ImageMagick portable installed to the Utilities folder. If ImageMagick is already installed, simply change the line set IMdir=C:\Utilities\ImageMagick\ to your ImageMagick location. Use double quotes if the path contains spaces (e.g., set “IMdir=C:\Program Files\ImageMagick\”). Be sure to use the latest version of ImageMagick since the newest version has improved image conversion options and processing.

convert_syslinux_rev4b.bat

If creating a customized splash screen, place it in the splashimages folder in the flash drive and change the file name in the appropriate menu configuration file(s) as below so it can be used on the next boot:

MENU BACKGROUND /splashimages/your image name.jpg

5. Customize Menu Configuration Files (optional)

After the flash drive is working properly, try to install bootable applications or Linux distros by modifying the boot options in the menu configuration files for Syslinux or in menu.lst for Grub4Dos. Some menu label entries are already provided in the Syslinux menus that were verified to work such as Slax, Grub4Dos, and a few others.

That’s it. If anything gets messed up, everything can just be reinstalled to start again from the beginning. Good luck.

splashConvertallPortableApps.com provides free and open source portable SW that can be downloaded and run separately from the PortableApps.com Platform™ management system. When launching apps independently from the platform, the splash screen can be annoying. Although an option exists to  disable the splash screen from the PortableApps.com Platform’s™ “Advanced Preferences”, this doesn’t apply to independent apps not using this platform. Thankfully, this is easily fixed by modifying a single file.

How to disable the splash screen for your application

  • Open the application’s folder and drill down to the /Other/Source directory.
  • In the Source directory open AppNamePortable.ini with a text editor. In some cases an .ini file already exists with the application’s name in this directory. In any case, there will only be one .ini file in this directory. Open this file and go to the next step.
  • Change the line DisableSplashScreen=false to DisableSplashScreen=true (see screenshot below. Click to enlarge).
  • Use “save as” to save the file with the name of the application and the .ini extension (e.g., ConvertAllPortable.ini).
  • Close the text editor and copy or move this file to the application’s main directory.

screen shot of disable splash

That’s it. The .ini file will override the default configuration when starting the application. There should be a noticeable difference in how quickly the application starts. If you still have a splash screen, make sure that the .ini file just moved to the application’s main directory is correctly named. For example, if the application name is ConvertAllPortable.exe, the .ini file should be ConvertAllPortable.ini.

Problem – no WiFi after Fresh Install

tux wonders why wireless doesn't workAfter an upgrade from Mint 13 to Mint 16 using the “fresh upgrade” method again resulted in a system without wireless connectivity, this guide was created for future reference and possibly as an aid to others experiencing the same problem. The information here applies to the B43 driver, specifically for the 4311 PCI-ID/Chip ID, but the driver/firmware solution described may be similar for other Broadcom PC-IDs also using the B43 driver (see list below) and running on Debian/Ubuntu or derivative distros; however, keep in mind that derivative doesn’t imply compatibility in all cases. For further information about B43/B43 legacy wireless devices and driver/firmware solutions see http://wireless.kernel.org/en/users/Drivers/b43.

Similar PC-IDs for B43:
14e4:4307
14e4:4311
14e4:4312
14e4:4318
14e4:4319
14e4:4320
14e4:4357
14e4:5354

Note that in most cases PCI-ID correlates to the Chip ID, but that is not always the case, so identify your device using the PCI-ID.

Regardless of the PCI-ID, always check the distro’s documentation and user forums for the most up-to-date information. Broadcom wireless solutions change constantly and often vary from distro to distro.

System used for this Guide

The system used for this guide was an Intel Pentium T2310 / 1.46 GHz ( Dual-Core ) laptop with Mint 16 (Mate) freshly installed to the hard drive. The built-in wireless device was based on the BCM 4311 chipset. No other options existed at the time for connecting to the Internet except for wireless, which wouldn’t work after the OS installation.

Broadcom Wireless Issues

In the past, wireless connectivity issues in Linux for devices using the popular Broadcom chipset were a common problem that often turned into a difficult, confusing and time-consuming task. Considerable time and effort was often spent performing multiple trial-and-error driver installations, command-line troubleshooting, reading and evaluating technical documentation, and following suggestions from other users to get wireless working.

Although some Linux distros support Broadcom wireless out-of-the-box or provide options within the OS to install the correct drivers/firmware, most do not because of a variety of ongoing development, proprietary and support issues. When users search the Web for answers, this often results in page after page of possible solutions and troubleshooting suggestions, many which may be out-of-date and therefore may no longer work. The amount of information can overwhelm and confuse users desperate for an easy and quick solution. An informative Archlinux.org Wiki entry (2013), Broadcom Wireless, describes many of these issues and illustrates why so much confusion and seemingly conflicting information exists about getting wireless to work for Broadcom devices in Linux.

Current Support Issues

Fortunately, driver/firmware support and installation options for Broadcom wireless devices have steadily improved and don’t require as much user effort or technical expertise as before; however, this doesn’t mean that problems are now a thing of the past. Many users may still need another PC to hunt the Web for the correct drivers, may find themselves the frustrating catch-22 position of needing a LAN connection in order to install the drivers, or learn that the correct drivers are not clearly specified, or when specified, are not included with the installation media.

For some Linux distros, B43 driver/firmware installation can be an automated or a semi-automated process. Some distros feature automatic installation for B43 devices by detecting and installing the appropriate driver package during the OS install from the installation media or through a LAN connection, and some may include them with the kernel image. Others, like Ubuntu/Debian and their derivatives, may even provide customized installation files (like a deb file) from their support forums or web site that can be downloaded and double-clicked to automatically install the appropriate drivers/firmware. Note that some deb files don’t include the drivers and may require a LAN connection in order to download them separately (another catch-22 situation if you don’t have a LAN connection).

When any of the previously mentioned B43 wireless driver/firmware installation options are not available or easily identified, users can still enable wireless using an extraction tool and the open source or proprietary drivers to manually install the firmware – this is the process described in this guide.

Generally, three categories of wireless driver/firmware solutions exist for Linux users with Broadcom chip-sets:

1. brcmsmac/brcmfmac/brcm80211 – Open source kernel driver (newest, often included with the latest kernel images)
2. B43/B43 legacy – Open source reversed-engineered kernel driver (B43 only is covered in this guide, B43 Legacy is not covered)
3. broadcom-wl – Proprietary Broadcom STA driver

The necessary driver/firmware is dependent on the chipset/PCI-ID, type of wireless device, operating system, CPU architecture, and the OS version (note that some Broadcom wireless devices are still unsupported in Linux). Regardless of the chipset/PCI-ID, the distro’s documentation and user forums should always be checked for the latest information since driver solutions and installation options vary from distro to distro and even between versions within a distro.

Identifying the Wireless Device

To identify a Broadcom wireless device in Linux, type the following command (case-sensitive) into a terminal:

lspci -vnn -d 14e4:

lspci terminal
The above is the output of the lspci command. The PCI-ID is identified within the brackets on the 2nd line by 14e4:4311, where 14e4 is the identification code for Broadcom, and 4311 is the device. In this case, 4311 also identifies the Chip ID. The <access denied> after Capabilities is displayed because the lspci command was executed without using administrator privileges (sudo or su).

Additional wireless identification and troubleshooting commands can be found at the Ubuntu Community Help Wiki.

Tested Solution – Install firmware from driver source file

The verified solution for this guide was to use another PC to download the necessary files onto a USB flash drive and then transfer those files to the user directory on the Linux Mint 16 PC with no Internet connectivity. The files needed were fwcutter (a deb file) and the Broadcom-wl proprietary driver source file. Fwcutter is a tool written for BCM43xx driver files to extract firmware from driver source files.

Steps:

1. Download b43-fwcutter for your architecture (bottom of page) from http://packages.debian.org/squeeze/b43-fwcutter. In this case, b43-fwcutter_013-2_amd64.deb was used, but an older version or a 32-bit version probably would have worked as well.

2. Download the source file from http://mirror2.openwrt.org/sources/. In this case, broadcom-wl-4.150.10.5.tar.bz2 was used. Scroll down the page to locate the broadcom files entries.

3. Transfer the files to your user directory on the Linux Mint PC and double-click the b43-fwcutter file to install it. Ignore any warnings about the version being out-of-date.

4. Run the following commands to extract and write the firmware to /lib/firmware. Ignore any warnings.

tar xfvj broadcom-wl-4.150.10.5.tar.bz2
sudo b43-fwcutter -w /lib/firmware broadcom-wl-4.150.10.5/driver/wl_apsta_mimo.o

5. Reboot the PC.

6. The wireless should now work. If so, look for and install any updated B43 wireless firmware/fwcutter/drivers using the Synaptic Package Manager. Do not use B43 legacy.

Recreating directory structures can be a tedious and error-prone chore, especially if using the right-click method to create multiple structures and folders. This guide describes three methods to easily copy directory structures (without files) in Windows: (1) with the command line, (2) with GUI tools dedicated for that purpose, and (3) by configuring a freeware file manager, FreeCommander, to enable this function.

http://clker.com

Copying Directory Structures from the Command-line

For those comfortable with the command-line, two commands that can be used for this purpose are the Xcopy and Robocopy, both of which have tons of options. Although others, such as the FOR command could also be used, Xcopy and Robocopy are by far the most popular tools used for this purpose.

Xcopy

Xcopy is included in systems up to Vista. It’s a more powerful version of copy with additional features that can copy files, directories, and whole drives. Note that although Xcopy is included with Vista, it has been deprecated in favor of RoboCopy.

To use Xcopy to clone a directory without files, use the following syntax:

xcopy /t /e "C:\Your Folder" "C:\New Folder"

/t = Copies the subdirectory structure, but not the files

/e = Copies subdirectories, including any empty ones

When using Xcopy with the above switches, you will be asked to specify whether the target is a directory or a file before the Xcopy command executes, but if the command is executed from a batch file, no user interaction is required.

Note: Xcopy doesn’t display any progress or completed operations information when executed.

Additional Xcopy commands can be found here.

Robocopy

Robocopy stands for “Robust file copy.” It’s a standard feature for Windows starting with Vista. It’s can also be installed in WinXP as part of the Windows Resource Kit.

To use Robocopy to clone a directory without files, use the following syntax:

robocopy "C:\Your Folder" "C:\New Folder" /e /xf *

same as above but without displaying the status:

robocopy "C:\Your Folder" "C:\New Folder" /e /xf * >null

same as above and creates a log (overwrites existing log):

robocopy "C:\Your Folder" "C:\New Folder" /e /xf * /log:yourlogfile.log

same as above and appends to log (appends to existing log):

robocopy "C:\Your Folder" "C:\New Folder" /e /xf * /log+:yourlogfile.log

/e = Copies subdirectories, including empty ones.

/xf = Excludes files matching the specified names or paths. Wildcards “*” and “?” are accepted

Additional Robocopy commands can be found here.

Note: Robocopy displays progress and completed operations information when executed as shown in the below screenshot.

Freeware GUI Tools for copying Directory Structures

Two easy-to-use GUI (graphical user interface) apps dedicated specifically to creating directory structures without files are TreeCopy and Miroirs:

TreeCopy – Portable and freeware. Runs on Win95 to Win8.

treecopy screenshot

Miroirs - Freeware. Requires installation. Runs on XP/Vista/Win7

Miroirs screenshot

FreeCommander setup to copy Directory Structures

FreeCommander is a freeware file manager that can be configured to copy directory structures using a customized batch file with the Xcopy and/or Robocopy commands. FreeCommander Ver. 2009.02b was used for this example. These instructions are modified from those provided on the FreeCommander forums.

FreeCommander Instructions

Create a batch file with the following code and save it with any name desired such as “copyFolderStructure_freecommander.bat.” For Xcopy the batch file’s main code consists of:

xcopy %1 %2 /t /e

%1 and %2 are the first and second parameters passed to the batch file (structure to copy and target)
The /t and /e options are the same as above

For Robocopy the batch file’s main code consists of:

robocopy %1 %2 /e /xf *

%1 and %2 are the first and second parameters passed to the batch file (structure to copy and target)
the /e and /xf * options are the same as above

Note: a pause can be entered at the end of either of the batch files above to keep the command window open for viewing the output

Example batch files for FreeCommander:
copyFolderStructure_freecommander_xcopy.bat
copyFolderStructure_freecommander_robocopy.bat

From the menu, select Extras->Favorite Tools->Edit or use (SHIFT+CONTROL+Y). Click the image below to enlarge.

freecommander menu

Select none from the left-hand column named Categories, then click once in the Items column.

FreeCommander Tools Configuration

Use the Items:Add to list button that appears above the Items column to create an item, for instance Copy Folder Structure.

Select Seek program by clicking the blue arrow next to the program field to navigate to and select the saved batch file’s (e.g. C:\tools\copyFolderStructure_freecommander_robocopy.bat) full path into the program field.

Enter the following into the parameter field:

"%LeftDir%" "%RightDir%" %Dlg%

The variables, %LeftDir% and %RightDir%, pass the address of the left and right folders to batch file parameters %1 and %2. The %Dlg% variable is optional and may be omitted if desired. It is used to display a Run program window (screenshot below) before actually starting the script to allow the folder names to be verified. It also provides a way for the operation to be cancelled.

dialog

If desired, add an icon by using the blue button next to the icon field to navigate to the icon’s location.

Make sure the boxes are checked as in the Define Favorite Tools screenshot above before hitting OK.

Tool Selection
The toolbar now contains an entry for copying Folder Structures. The tool can be selected from the menu with Extras->Favorite Tools->Name of your tool or by using the favorites icon (make sure Extras is enabled in Extras->Settings->View->Toolbar if it’s not visible on the toolbar).

Using FreeCommander

To use, select the structure to copy in FreeCommander’s left pane and select the target directory in the right pane. Select and click your tool from the toolbar or menu as described above. After the Run program dialog appears, click OK to continue.

FreeCommander Select

Xcopy doesn’t provide an option to display progress or completed operations. However, with Robocopy, the output will display the copy operation details as shown below (a pause was used in this batch file):RoboCopy Output

If no errors occur, the folder structure will be copied as in the following screenshot:

Since version 1.98, GRUB 2 began replacing GRUB version 0.9x, which is now known as GRUB legacy. GRUB 2 represents a major revision over its predecessor to make it more portable and modular. And although GRUB legacy is no longer being developed, bug fixes for it continue, and it’s still used as the default boot loader for a number of Linux distros. Over time, GRUB 2 usage has steadily increased and while still a work in progress, it’s probably the most common boot loader for Linux distros. Although GRUB 2 is officially known as GRUB, Linux distro repositories may include GRUB 2, GRUB legacy, or both versions. Repositories that include both versions may make the distinction between them as GRUB 2 and GRUB, GRUB and GRUB legacy, or GRUB 2 and GRUB legacy. The naming inconsistency between distros can be somewhat confusing, but this is to be expected during any transition.

What is covered in this guide

This is not a comprehensive guide on GRUB 2; rather, this is a quick reference covering frequently used GRUB 2 tweaks and option edits for most Linux distros; particularly those based on Debian/Ubuntu or Slackware. For detailed information about GRUB 2, see the references at the end of this guide.

This guide assumes that the reader already has GRUB2 installed for a single boot or a multiboot Linux system. Note that all changes to GRUB 2 options must be done while logged in as root or by use of sudo.

GRUB 2 summary

Recent converts to GRUB 2 probably have noticed that the Boot menu basically looks the same as GRUB legacy. Although they appear similar, the way GRUB 2 generates its menu is very different. Also, GRUB 2 now places its files in three locations:

  • /boot/grub/grub.cfg  (GRUB 2 main configuration file, replaces menu.lst, a product of the script files in /etc/grub.d/)
  • /etc/grub.d/  (directory containing several GRUB 2 script files)
  • /etc/default/grub  (GRUB 2 customization file)

Most GRUB 2 files are updated/regenerated automatically during package updates, when new kernels are added, after installing additional OS’s on multi-boot systems, or whenever GRUB is manually updated after making changes to the GRUB options as described in this guide. Generally, editing these files is not recommended, not only because it can cause boot problems, but also because most of the files will be overwritten anyway during system updates. The single file that users can generally edit without issue is /etc/default/grub, which holds most of the settings that will be of interest to users reading this. This file contains customization settings such as the default menu entry, timeout, default boot, graphics, and more. An example GRUB file from Lubuntu 12.10 (original settings slightly modified) is shown below:

# If you change this file, run '<strong>update-grub</strong>' afterwards to update
# /boot/grub/grub.cfg.
# For full documentation of the options in this file, see:
# info -f grub -n 'Simple configuration'

<span style="color: #000000;">GRUB_DEFAULT=0</span>
<span style="color: #000000;">#GRUB_HIDDEN_TIMEOUT=0</span>
GRUB_HIDDEN_TIMEOUT_QUIET=true
<span style="color: #000000;">GRUB_TIMEOUT=-1</span>
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
<span style="color: #000000;">GRUB_CMDLINE_LINUX_DEFAULT=""</span>
GRUB_CMDLINE_LINUX=""

# Uncomment to enable BadRAM filtering, modify to suit your needs
# This works with Linux (no patch required) and with any kernel that obtains
# the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...)
#GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef"

# Uncomment to disable graphical terminal (grub-pc only)
#GRUB_TERMINAL=console

# The resolution used on graphical terminal
# note that you can use only modes which your graphic card supports via VBE
# you can see them in real GRUB with the command `vbeinfo'
<span style="color: #000000;">GRUB_GFXMODE=auto</span>

# Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux
#GRUB_DISABLE_LINUX_UUID=true

# Uncomment to disable generation of recovery mode menu entries
#GRUB_DISABLE_RECOVERY="true"

# Uncomment to get a beep at grub start
#GRUB_INIT_TUNE="480 440 1"

Quick Edits for /etc/default/grub

Note: A grub file can contain many more options than those shown in the above file. For a full list of options refer to the GNU Grub Manual (link in reference section below). Note that all GRUB 2 commands or changes to its files must be done while logged in as root or by using sudo.

As previously mentioned, the above sample GRUB 2 file is essentially the same as the default file for Lubuntu ver. 12.10. Note that the option entries listed in the above file may differ for other Linux distributions and/or versions. In most cases, users will want to make minor changes to the option entries that are common to all distributions and/or versions, such as timeout, default boot OS, displayed boot information (quiet splash), or the display resolution. To enable a listed option, remove the comment (#) in front of the option entry and change its value as appropriate. If a desired option is unlisted, it may be added to the end of the file. Also notice that the above file contains comments that provide information for enabling/disabling many of the listed options. After making any change to this file, it must be saved and GRUB updated in order for the changes to take effect on the next boot (see saving and updating section below). A few common option entries are described as follows:

GRUB_DEFAULT=0
Default option setting is 0.
This is the default menu entry to be booted. Zero (0) is the first boot option listed in /boot/grub/grub.cfg.

GRUB_TIMEOUT=-1
Default option setting is 5.
Sets the time in seconds that the boot menu displays before it automatically boots the default boot entry. If a key is pressed before that time, the timeout is cancelled, allowing manual selection of the entry with no time limit. The value “-1″ causes the menu to be displayed indefinitely.

GRUB_CMDLINE_LINUX_DEFAULT=””
Default setting is distro dependent.
Passes arguments to the end of the boot command line for the kernel of the menu’s default entry. Added in addition to any arguments specified in GRUB_CMDLINE_LINUX below. This option is often set to “quiet splash” to suppress boot information and display the splash screen. Note that “quiet” and “splash” are separate values. Remove “quiet splash” between the parentheses to display all boot information without a splash screen.

GRUB_CMDLINE_LINUX=””
Default setting as above.
Passes arguments to the end of the boot command line for the kernels of all the menu entries.

GRUB_GFXMODE=auto
Default setting is “auto”.
Sets the graphical terminal resolution. Only modes supported by the graphics card VESA BIOS Extensions (VBE) can be used. To determine the available screen resolutions, type “c” for a command line at the GRUB 2 boot menu and then enter “vbeinfo.” The syntax for the option value is widthxheight[xdepth]. Some common option values are 1400x900x32, 1024×768, and 800×600.

#GRUB_DISABLE_RECOVERY=true
Recovery mode entries are generated by default.
Enable by removing #, which will disable generation of the recovery mode entries; otherwise, for each Linux kernel, at least two menu entries will be generated – the default entry and a recovery mode entry.

Saving and updating the edited /etc/default/grub file

After editing and saving the /etc/default/grub file the following command must be executed for the changes to take effect:

sudo update-grub

To restore the default settings for GRUB 2, reinstall GRUB 2 by executing the following command:

sudo grub-install /<target>

Where <target> /dev/sda, /dev/hda

GRUB 2 tools

Graphical tools for configuring Grub 2 have become more common as Grub 2 matures. One GUI tool now available on many repositories is grub-customizer. See this How-to-Geek article for a description of this tool.

Placesbar Editor is a freeware tool that provides a convenient way to change any of the five folders on the Places Bar menu to whatever you want without directly editing the registry. PlacesBar Editor works in Windows 2000/ME/XP/Vista and Office. For Vista and above, the ability to change the Places Bar is built into the operating system, but apparently not for the Basic and Home Editions of Vista or Win7. For Vista or Win7 versions other than the Basic or Home editions, see WinVistaClub’s article: How To Add Your Own Folders To The Places Bar Or Favorite Links. In any case, for XP and older systems, this is a must-have utility. For further information, see the review on PlacesBar Editor at Freeware Genius.

This guide describes how to setup a text editor to use the Visual C++ Studio Express compiler. Although many IDEs, including Visual C++ Studio, can edit code, text editors (a.k.a. programming or code editors) are often simpler, faster, are easier to use and configure, and have a shorter learning curve, especially since many users already use them and are thus familiar with the interface. In addition, many older and slower computers don’t have the resources to run IDEs such as Visual Studio very efficiently.

Many of the popular free compilers once used with text editors are now considered outdated. Today, the trend is towards using dedicated IDEs to write and compile code in an integrated environment such as Visual C++ Studio, or with other IDEs designed to be compatible with one or more independently developed compilers. Because IDEs have largely replaced the now out-of-fashion text editor as the standard coding environment, many text editors are no longer developed, supported or updated specifically for use with compilers. Because of these factors, many text editors may no longer work easily with up-to-date compilers. This guide provides one workaround solution.

The instructions for this guide were tested on a PC running Windows XP SP3, Visual C++ Studio Express 2010, and using the PSPad (ver 4.5.3) text editor. The instructions should be similar for other versions of Windows, Visual C++ Studio editions, and other text editors.

Visual Studio’s compiler is the cl.exe executable located in the “C:\Program Files\Microsoft Visual Studio 10.0\VC\bin\” directory. Without getting into all the technical details, this file only executes properly within Visual Studio’s integrated environment, so directly setting it up in PSPad’s highlighter settings won’t work. In fact, even if you try to execute cl.exe from a Windows Command window within Visual Studio, you will get an error. The solution is to compile from Visual Studio’s command window, which looks just like a regular Windows Command window, but is actually the Visual Studio environment. To accomplish this, the source code file from the text editor is passed to a batch file, which starts Visual Studio’s environment and compiles the file. Sounds somewhat complicated, but it’s simple once explained.

Below is the batch file code:

@echo off

REM This file allows text editors to compile C++ files in Visual C++.

REM Modified from the shortcut in Program Files
CALL "C:\Program Files\Microsoft Visual Studio 10.0\VC\vcvarsall.bat"

REM For 32bit Intel Processors
rem CALL "C:\Program Files\Microsoft Visual Studio 10.0\VC\bin\vcvars32.bat"

cl.exe /EHsc %1

pause

Basically, the batch file consists of only four lines: (1) @echo off, (2) CALL the Visual Studio environment, (3) pass the source file to cl.exe with parameters, and (4) pause. That’s it. Copy the code and save it with a .bat file extension. I saved my file as vsbat.bat. There are two CALL commands in the batch file to two batch files in VS (Visual Studio). The first (vcvarsall.bat) is the path taken from the shortcut for the VS Command window in the start menu and slightly modified for use in the batch file above. The other (vcvars32.bat), is the path for the VS environment batch file for 32bit processors in the “VC\bin\” directory. If you have another processor, or use another edition of VS, either batch file may have a slightly different path, name and/or contents depending on your processor. If any of the paths are different from those above, just right click on the VS Command prompt icon in the start menu and and select properties to get the path and change the above batch file accordingly. In any case, both CALL statements just start the VS environment in a Command window according to the processor type. In the above batch file, the 32bit Intel Processor command is commented out but left in for information purposes. The first one should be the only one necessary. The cl.exe command starts the compiler with the “/EHsc” option which tells the compiler not to throw a C++ exception and “%1″, which is the source file parameter passed to the batch file. Finally, pause just keeps the command window from closing.

Save the above batch file somewhere on your PC and start PSPad. Select Settings->Highlighter Settings->C/C++->Compiler Tab in PSPad’s menu. Enter the information as shown in the screenshot below (click to enlarge image):

PSPad compiler settings

For the Compiler setting, enter the path to the batch file you saved (vsbat.bat). For the Parameters setting, enter “%File%” (with parentheses), which is the source file currently loaded in the editor. The Default Directory entry is optional and self-explanatory. For the Run after Compilation setting enter “cmd.exe /K %Name%.exe” to automatically run the executable after compilation (after closing the VS Command Window). Check the Save All Files Before Compilation box and hit OK to save the settings. That’s it. PSPad is ready to compile C++ source files with Visual Studio and to run its executables.

unknown exception dialogAn unknown Exception may occur when launching Notepad++ ver. 5.9 (Unicode) or later. This problem appeared on a PC running WinXP SP3 32-bit, and according to information on Sourceforge, the issue may also apply to Vista, but not Win7. The cause appears to be four plugins that may be incompatible with the updated version of Scitilla.

The four plugins are:

  • AHKExternalLexer.dll
  • ExternalLexerKVS.dll
  • NppExternalLexers.dll
  • Oberon2LexerU.dll

Update (03/21/13): Many users experiencing the unknown exception issue with Notepad++ versions since 5.9 have resolved the problem by uninstalling the PreviewHTML.dll or another plugin instead (see the comments for problem plugins).

Users can move the plugins one at a time into another folder within the “plugins” folder and relaunch the program to identify the plugin(s) responsible. In the case of the WinXP PC noted above with this problem, it was necessary to move a single plugin, the NppExternalLexers.dll file, into another folder (e.g., disabled_plugins) to get Notepad++ to launch without error. Any responsible plugin(s) causing the problem may also be deleted or renamed so they won’t load.
