Hi keerbear412
First is your bios up to date?
Second, do you have a floppy in drive A?
Third, are you accessing the proper area of your bios. Like in my bios, it has a section called "IDE configuration which shows the various drives on the cabling."
But the order in which the computer looks for a boot system is found in something like "Boot device priority" in which one can set the sequence that your computer will look for a bootable disk.
Finally, as a last resort, you may wish to look at my thread "Booting a CD from a floppy" in this Forum (Windows NT/2000/XP)
