[comp.sys.ibm.pc.hardware] lowlevel hardward format doesn't work

	I've had an odd problem with both of the Western Digital drive
controllers I've ever owned.

	Both have told me to type
DEBUG<return>
g=C*00:5<return>

Where * has been, alternatively, 8, A, and C.  None of those works- they either
lock up the machine or "break", giving me a stack dump.

	When I do a dump, I.E.
DEBUG<return>
DCC00:5<return>

	I get what looks like, perhaps, code, but nothing really interesting
like text.  This is really annoying because it's done this for both my old
drive controller (which didn't have any documentation) and the new (which comes
with scads of documentation, none of it useful).

	I fear this may be a silly BIOS problem- I've got a Phoenix BIOS that
came with the MIT systems 286 (from Telemart).  The old controller card was
simply a WDC-- I don't know the model number, but it ran an MFM 42meg CMS.

	The new controller is a WDC1006RA2 HDFD running an RLL 65meg Seagate
ST277R and the old 42meg CMS formatted at 65meg.
