I am experiencing trouble installing a Toshiba ND3561 3.5" HD floppy
drive in my AT&T 6310. The only working configuration that I found
is in 720 KB mode. I am using AT&T Diagnostics/Setup Disk Ver. 1.03
that does not allow a 1.44 MB floppy drive selection. Making the
Toshiba drive operational required changing the floppy drive jumpers
for pin no. 2 from OPEN to INPUT LOW=2 MB and HIGH=1 MB. The jumper
settings on the floppy drive controller card are set for dual 1.2 MB
drives by using the following connections: HC-A, HC-B.

Other AT setup utilities have been tried without any success. Does
AT&T use a proprietary setup scheme, requiring me to upgrade the
Diagnostics/Setup disk? Furthermore, do I need to reset my floppy
controller card jumpers as well?

Please email and I will summarize if there is sufficient interest.
