It gives info on creating a DOS boot disk for Windows 2000

Are you looking for a MS-DOS boot disk or a startup disk for booting a system and installing W2K.
(based on your previous question)

I looked at both a W98 and XP system, and both have a check box on the floppy format screen to create a MS-DOS boot disk.

If what you need is a startup disk for W2K, there is a utility on the CD that creates the 3 disk floppy boot set.

Or, you should be able to set the system to boot from the CD.

For flashing your BIOS, just about any DOS boot disk will work.

Another way to create a DOS boot disk is to run the command
sys a:
with a blank formatted floppy in the drive.
This does not work on my XP box, but will work from any older Windows startup disk.

Another alternative is to check out the boot floppy images at www.bootdisk.com
