[comp.sys.ibm.pc.hardware] CMS Hardcard in PC 6300+, Help

davet@cbnewsj.att.com (Dave Tutelman) (11/25/90)

I'm trying to add hard-disk capacity to my AT&T PC 6300 PLUS,
in the form of a 32 MB CMS Hardcard Plus.  So far, no luck.
And it's kind of hard without the manual (I got it used, no manual).
I need either:

 - The phone number for CMS tech support, or
 - Some help on settings to make it go.

The hardcard itself is a lashup of two standard components:
an ST138 disk drive and a WD 1002A-WX1 controller.

Also, in my unsuccessful attempts, I've managed to trash the low-level
format on the drive.  That's OK (no data there anyway), but I can't
reformat it with any of the utilities I've used so far (OnTrack Disk
Manager, OPTIM, or AT&T's own LOWFORM).  I suspect, but I'm not certain,
that it'll be better once I get the right configuration.

Any suggestions?  Even just encouragement?

Thanks in advance.
Dave

I believe any WD controllers for the XT type machine (8 bit card) has
the same way to low level format. Go into debug and at the - prompt:

-g=c800:5

and that will bring up the low level formatter. Don't forget to
FDISK then FORMAT it after it is done.
