Why customize?

Do to license restrictions, the Ultimate Boot CD does not contain boot disks of commercial software eg. MS-DOS, Windows, Ghost etc. It also does not contain boot disks specific to your environment eg. network drivers, SCSI drivers etc. Finally, it may not always contain the most up-to-date virus definitions. This section talks about how to create your own customized Ultimate Boot CD, tailored to your specific needs.

Extraction

First, extract all the files on the UBCD to a directory on your harddisk such as c:ubcd-exracted (pathname may contain spaces). If you wish, you can directly extract the files from the ISO image using a tool such as 7-Zip or Daemon Tools.

You should have a directory structure that looks like:

c:ubcd-extracted
boot
pmagic
ubcd
custom
custom.cfg
custom.lst
autorun.inf
license.txt

Adding floppy images

To add your own floppy images to UBCD, copy them to c:ubcd-extractedubcdcustom. Floppy images can be created from the physical floppy disks by using utilities such as rawread. You can optionally compress each image using gzip (via a tool such as 7-Zip) to make them smaller.

Then edit c:ubcd-extractedubcdcustomcustom.cfg and add each floppy disk image to the menu.

For example:

LABEL -
MENU LABEL MS-DOS V6.22
TEXT HELP
MS-DOS boot disk
ENDTEXT
LINUX /boot/syslinux/memdisk
INITRD /ubcd/custom/msdos622.img.gz
APPEND raw

Adding ISO images

To add your own ISO images to UBCD, copy them to c:ubcd-extractedubcdcustom. You can optionally compress each image using gzip (via a tool such as 7-Zip) to make them smaller. Then edit c:ubcd-extractedubcdcustomcustom.cfg and add each ISO image to the menu.

For example:

LABEL -
MENU LABEL Windows 98
TEXT HELP
Windows 98 boot disk
ENDTEXT
LINUX /boot/syslinux/memdisk
INITRD /ubcd/custom/win98.iso.gz
APPEND iso raw

Note that not all ISO images can be successfully booted this way. Real mode OSes and boot loaders that use INT13 BIOS calls will likely work, but other may not. For more information, refer to the memdisk documentation on ISO image support.

Adding FreeDOS-based applications

The FreeDOS boot image and the various DOS apps (compressed in CAB archives) are located in a 16MB superfloppy at c:ubcd-extractedubcdimagesfdubcd.img.gz. To modify this image, you need to uncompress it using 7-Zip or equivalent to fdubcd.img, then load the image using DiskExplorer, WinImage or a similar utility.

You should have a directory structure that looks like:

bin
custom
dosapps
etc
level1
level2
level3
lib
autoexec.bat
command.com
config.sys
diskid.txt
kernel.sys

To add a DOS app to UBCD that is launched via FreeDOS, first create a CAB archive of the application files. For example, suppose you wish to add a DOS program found in c:myapp which comprises of the following files:

c:myapp
app.exe
app.dat

Create the CAB archive myapp.cab by using CabPack V1.4a (Local mirror). Recommended settings: CompressionType (LZX), CompressionMemory (21), Create cabinets for (32bit extractor)..

Alternative tools that support CAB archive creation includes IZArc and CL-Tools 4Win. Note that other archive formats such as zip and 7z can be used too.

Next edit customcustom.ini in fdubcd.img and append at the end:

[User Defined]
myapp; 'app.exe'; -$; My custom application

The section name [User Defined] is listed as a submenu under FreeDOS when you type 'ubcd' at the command prompt.

The items under the section name are the individual DOS programs. Each line comprises of four parameters, separated by semicolons.

Finally, append this section to c:ubcd-extractedubcdcustomcustom.cfg:

LABEL -
MENU LABEL MyApp V1.0
TEXT HELP
My custom application
ENDTEXT
COM32 linux.c32 memdisk
INITRD /ubcd/images/fdubcd.img.gz
APPEND floppy raw c=32 h=16 s=63 ubcdcmd=myapp

^*1 When working with DOS files, remember to observe the 8.3 limitation of DOS filenames. This includes the filename of the archive files as well as the filenames of the files found with it.

^*2 In general, try to avoid extracting to paths containing spaces (eg. C:Documents and SettingsUserUBCD Extracted) to reduce complications. If you absolutely have no choice, remember to delimit paths containing spaces with double-quotes when entering commands (eg. 'C:Documents and SettingsUserUBCD Extracted')

Converting menu commands to grub4dos format

UBCD offers two bootloaders: syslinux/isolinux (default) and grub4dos. The file custom.cfg contains the menu commands for syslinux/isolinux. If you plan on using grub4dos at some stage, you can convert the menu commands automatically to a format that grub4dos understands (found in custom.lst). To make the conversion, at the command prompt, type:

cd ubcd-extractedubcdtoolswin32syslinux2grub4dos
syslinux2grub4dos

Updating anti-virus databases

Under c:ubcd-extractedubcdtoolswin32antivirus, there are two scripts clamav.cmd and fprot.cmd that help update the antivirus databases for the two antivirus engines included in UBCD (ClamAV and F-Prot; found within Parted Magic). You need an Internet connection for these scripts to work. Simply run the scripts to update the antivirus databases when you create a customized/updated version of UBCD.

Generating customized ISO image

At the command prompt, type:

cd ubcd-extractedubcdtoolswin32ubcd2iso
ubcd2iso c:ubcd-extracted c:ubcd50-custom.iso

This will create ubcd50-custom.iso in C:.

To create a bootable UBCD memory stick, at the command prompt, type:

cd ubcd-extractedubcdtoolswin32ubcd2usb
ubcd2usb c:ubcd-extracted x:

where X: is that drive letter of USB memory stick, which is assumed to be already formatted. If it is not already formatted, or you wish to force it to be formatted, you can add the /f switch at the end:

ubcd2usb c:ubcd-extracted x: /f

Either of the above will create a bootable UBCD memory stick in X:.

Note that booting a USB memory stick requires BIOS support and is only available on newer machines. You can also expect to encounter more compatibility issues compared to booting from a CD, and some tools may not work properly when run from a USB memory disk.

For Linux users...

For those running Linux, the equivalent tools for syslinux2grub4dos, ubcd2iso and ubcd2usb etc. are available under ./ubcd-extracted/ubcd/tools/linux.

You may need to make the tools executable:

$ cd ./ubcd-extracted/ubcd/tools/linux
$ chmod a+x ./*/*.sh
$ chmod a+x ./ubcd2usb/syslinux
$ chmod a+x ../../../antivir/antivir

Upgrading to a newer version of UBCD while preserving customization

The advantage of limiting your customizations to c:ubcd-extractedubcdcustom is that it makes it easier to upgrade to a newer version of UBCD later.

If you have a customized fdubcd.img.gz that you want to preserve, then you need to overwrite the custom subdirectory in the new image with the one from your older, customized image.

Finally run ubcd2iso.cmd to create the new customized UBCD ISO image.

Replacing Parted Magic with your Linux distro of choice

The Linux distro Parted Magic is now included with UBCD since it is a more reliable way of accessing NTFS filesystems and USB devices compared to DOS. Most of the payload in Parted Magic can be found in c:ubcd-extractedpmagic, so if you wish to get rid of Parted Magic and include your own Linux distro instead, you can reclaim most of the space by deleting c:ubcd-extractedpmagic, adding your own distro to c:ubcd-extracted and adding a section in c:ubcd-extractedubcdcustomcustom.cfg to launch it.
