[comp.sys.ibm.pc] XT low level format parameter modification help needed

leoh@hardy.hdw.csd.harris.com (Leo Hinds) (03/16/90)

HAVE:
	true blue IBM PC (ok BIOS date)
	EVEREX HD controller, 1986 vintage - works (BIOS 3.93)
	Seagate ST4038 (30MB full height, 40ms, 733Cyl, 5hd)

NOTES:
	1) Used to use Seagate ST4051 (40MB 977Cyl/5hd) on this same 
	   controller, but the drive died.
	2) System has functioned since ~1986 with old disk

PROBLEM:
	1) controller thinks my drive has 977Cyl,5hd so I can not successfully 
	   low-level format the disk.
	2) g=c800:5 calls up WD (wx2 - rev 6) format routine which DOES NOT 
	   allow the manual specification of Cyl/heads

NEED:
	A means of low level formatting that will allow me to specify the disk 
	parameters, without changing controller.
	
	Or, if there is some way (using Norton/debug/??) for me to manually 
	modify the disk (I assume that's where the controller is getting the 
	info from) so that the correct number of cylinders will be formatted?

Get rid of the everex controller and get a "real" one. Everex
makes good money selling different roms to allow you to do this
kind of thing.  DTC makes some pretty good ones as well as
western digital.

The upshot is that while everex is pretty good overall, the
equipment is just a touch on the weird side.  example...

I have an everex 2400 internal modem in a turbo XT clone...
so far so good, in turbo mode it will dial, connect and dump
the call every time UNLESS I'm using Bitcom (the software that
comes with the modem, take my word for it... real brain dead, it
makes smartcom look inteligent), or Crosstalk Mark4. The weird part
is that everything will work just fine if I shift out of turbo (8Mhz).

Everex's response is that "turbo doesn't make the modem go faster,
so it shouldn't be used".  That is certainly true but it definately
does spped up disk/memory/etc.

Like said, they're just a little bit weird.
