HELP! Please?
I have an IBM AT, with an AT-339 (fairly standard) motherboard,
and the Award BIOS 3.01B. My problem is that I need to use and
configure the CMOS RAM for hard disk type 40 on fixed disk 1 (C:),
but the hard disk tables in the BIOS only support up to 27 or so!
All the other entries are zero's!!
This means I need a new BIOS (mine already is dated Jan 1 1988)???
If it is pertinent, the controller is a Western Digital WD1002-WA2
Revision RX1, dated 1984, and the disk is a Seagate ST-251 (40ms).
Right now it runs as type 3, but it is WICKED SLOW (Norton DI of 0.3).
Thanks for all your help in advance!

Get a copy of Ontrack Disk Manager (it should have come with the drive, if not complain to the people you bought the drive from) and use that to reformat. Use an interleave of at LEAST three, proably four. I'd bet that your interleave is set to 2:1, which is not enough -- and thus the reads are "missing". Alternately get a WD1006-MM2 for the system, and run 1:1 interleave. That combination will smoke, and work well. Don't bother updating the BIOS -- it won't make a difference. -- Karl Denninger (karl@ddsw1.MCS.COM, <well-connected>!ddsw1!karl) Public Access Data Line: [+1 312 566-8911], Voice: [+1 312 566-8910] Macro Computer Solutions, Inc.
