C:\Documents and Settings\User\UBCD Extracted) to reduce complications. *2 In general, try to avoid extracting to paths containing spaces (eg. This includes the filename of the archive files as well as the filenames of the files found with it. *1 When working with DOS files, remember to observe the 8.3 limitation of DOS filenames. The fourth parameter is the name that will be displayed under the submenu for the tool.įinally, append this section to c:\ubcd-extracted\ubcd\custom\custom.cfg:ĪPPEND floppy raw c=32 h=16 s=63 ubcdcmd=myapp $$ : drop to the command prompt so you can add switches to your program (handy for programs that require extra parameters) The third parameter controls what to do after the program terminates: In this case, it will run app.exe (this file comes from the extracted myapp.cab). The second parameter is the command line to run for the specific program. In this case, it will look for myapp.cab, myapp.zip, myapp.uha and myapp.rar on the entire CD or disk, so make sure you specify a unique name that can be found anywhere else on the CD or disk. Each line comprises of four parameters, separated by semicolons. The items under the section name are the individual DOS programs. The section name is listed as a submenu under FreeDOS when you type "ubcd" at the command prompt. Next edit custom\custom.ini in fdubcd.img and append at the end: Note that other archive formats such as zip and 7z can be used too. Recommended settings: CompressionType (LZX), CompressionMemory (21), Create cabinets for (32bit extractor).Īlternative tools that support CAB archive creation includes IZArc and CL-Tools 4Win. For example, suppose you wish to add a DOS program found in c:\myapp which comprises of the following files:Ĭreate the CAB archive myapp.cab by using CabPack V1.4a ( Local mirror). To add a DOS app to UBCD that is launched via FreeDOS, first create a CAB archive of the application files. 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. The FreeDOS boot image and the various DOS apps (compressed in CAB archives) are located in a 16MB superfloppy at c:\ubcd-extracted\ubcd\images\. ![]() For more information, refer to the memdisk documentation on ISO image support. Real mode OSes and boot loaders that use INT13 BIOS calls will likely work, but other may not. Note that not all ISO images can be successfully booted this way. Then edit c:\ubcd-extracted\ubcd\custom\custom.cfg and add each ISO image to the menu. You can optionally compress each image using gzip (via a tool such as 7-Zip) to make them smaller. To add your own ISO images to UBCD, copy them to c:\ubcd-extracted\ubcd\custom. Then edit c:\ubcd-extracted\ubcd\custom\custom.cfg and add each floppy disk image to the menu. Floppy images can be created from the physical floppy disks by using utilities such as rawread. To add your own floppy images to UBCD, copy them to c:\ubcd-extracted\ubcd\custom. You should have a directory structure that looks like: If you wish, you can directly extract the files from the ISO image using a tool such as 7-Zip or Daemon Tools. This section talks about how to create your own customized Ultimate Boot CD, tailored to your specific needs.įirst, extract all the files on the UBCD to a directory on your harddisk such as c:\ubcd-exracted (pathname may contain spaces). Finally, it may not always contain the most up-to-date virus definitions. ![]() It also does not contain boot disks specific to your environment eg. Do to license restrictions, the Ultimate Boot CD does not contain boot disks of commercial software eg.
