	I worked on a IBM PS/2 Model 80 and had simular problems when I was
doing a project dealing with the Floppy Controller. It seems that the 
SPECIFY command cannot accept the same values for the PS/2 as for the AT.
Theses exact values can be located in lower memory (I believe somewhere below
0x4000 - See the PS/2 BIOS Tech Ref for the location). Unless the controller
is given the correct values, it will cause things like: loss interrupts, 
bad read/writes, media change status, and various other *wonderful* problems.

	I hope this helps some...
