Everything depends on what you want. Direct floppy emulation is the
easiest, many Windows CD-writing programs support that (Imgburn for
1) Download a bootable floppy image (MSDOS or FreeDOS)
2) Open in WinImage, change size to 2.88MB or leave at 1.44MB
3) Delete all contents besides kernel.sys and command.com.
4) Insert flasher program and the BIOS file (if it even fits anymore on
5) Add an autoexec.bat that executes the flash program. Only if you're
absolutely sure though and want to automate. This can ruin systems if
things go wrong!
6) Save the image
7) Open Imgburn, Nero or whatever, create a bootable CD and supply the
floppy image file you saved in step 6.
My own requirements for FreeDOS CD go a lot further with regard to
bootloader, floppy contents, detecting CD contents, executing it etc.
Slightly more complex, I'm afraid.

See if any of the various responses are enough to help you out. A
bootdisk can generally be obtained from www.bootdisk.img (but those
images are executables with WinImage compression, so you need to open
WinImage, then select to open an image and look for your saved floppy

Goodluck doing so. I'm working on creating a remaster ability in FreeDOS
which has limited use because there's most CD-recording software in DOS
is Linux-based and thus depends on something called ASPI, for which only
paid legal solutions exist.
