  the one floppy deal is not really a bios issue, it is
a hardware
 issue. As long as there are two drive select lines coming from the
 hardware, then the mb can supprt two drives even if there is not bios
 support. My ASUS P4 mb only supports one drive and I suspect that
 there is only one drive select. Bios code is meant to support the
 hardware that is present. At least that is the way is has been for 23
 years... 
That's like mine.  The motherboard only has one drive select line, so
the BIOS normally shows only one entry for a floppy.  However, if I
disable the on-board FDC and add a normal FDC card, I can use two
floppies and the BIOS detects and shows settings for both.
