Message-ID: <4c6EBgS00Uh700iaAW@andrew.cmu.edu> Date: 27 Apr 91 04:51:56 GMT Organization: Class of '91, Carnegie Mellon, Pittsburgh, PA Lines: 14 Help! I've replaced the 286-10 motherboard in my AT clone with a 386DX motherboard running at 16/20 Mhz, with AMI bios w/setup & xsetup in rom (APR 9, 1990). ^floppy The problem is that all three drives refuse to format floppys.They all report sector 0 bad and refuse to continue. They're set correctly in setup, they can read and write on pre-formated disks, and all other system functions are working ok. Two are on a standard MFM hard/floppy card, the other (720k) is on it's own drive card w/bios. Ive tried removing the 720k, changing wait states, other dos versions, pulling all cards out to no avail. Can anyone help with this problem, or at least provide a phone# for AMI?
