The 486 uses the 5.25 drive to read the boot disk. Thanks for the help, I appreciate it. Win 3.1 does not have a boot disk per se. There might be an easier way of going about that, but I'm not sure.
Disks are pretty much always in the first group.
If you change the wrong thing, it's possible to turn on your PC and never see anything on the screen again. Once in BIOS, you will see some type of menu. Again, the first choice will probably have the drives in it. It will show your hard drives, then your floppies. Highlight the one that says 5.25.
