[comp.sys.ibm.pc.hardware] Anyone using a 1.44M drive in an AT&T 6300 with BIOS 1.43?

jlt@cbnewsc.att.com (jeffrey.r.light) (04/28/91)

I have changed the 360K 5.25 drive to a 720K 3.5 drive and have NO problems.

BUT I can not make a 1.44 drive work as a 1.44, only at 720K.
I have run DOS 3.3 and DOS 4.01 and have installed DRIVPARM, etc, but
NO Success.

Has ANYBODY made the AT&T 6300 operate with a 1.44 drive.
I have considered disabling the internal drive controller and
buying a controller card, but do not want to waste time, if it
can not be done.

Thanks for any help.   Jeff  att!ihc!jlt
