"If you weren't using 1.44Mb floppies, then something went very wrong.
Otherwise, I'm not sure how the above could be related to the failure
you are seeing."

I always use floppy 3.5' 1.44MB.

Does the use of FDD depend on CMOS Floppy Disk Controller settings? I noticed that WinXP display FDD in My Computer window (http://savepic.net/4018623.htm):

- if coreboot + CMOS default from vendor BIOS: A: 3.5'

- if coreboot + CMOS clear: A: 5.25' and B: 5.25'

Maybe need apply CMOS.layout file to coreboot to resolve this problem? I just do not know how to make this file for Abit BF6 mobo.
