I just picked up a Packard Bell Pack-Mate PB800. It's got the following specs:
I was hoping to use this box as a general-purpose MFM drive tester and formatter, but I can't seem to find the Winchester controller BIOS, and no drives are being recognized. Now, it's been a while since I actively used a 286 -- I'm sure I'm just missing something obvious here, so hopefully someone can help me.
I've tried the obvious addresses. I boot DOS 5.0 off a floppy and run DEBUG, then I do:
-D C800:0
-D CA00:0
-D CC00:0
-D CE00:0
But none of these return anything but FF FF FF FF FF FF... There appears to be no WD1003V-MM2 ROM BIOS at any of the expected addresses!
There are a whole slew of C&T CS8221 BIOS settings dealing with EMS and shadowing, but it's been so long that I honestly don't remember what they do. One of the obvious ones is "EMS Base Address at C800", which I would expect to conflict with the expansion cards -- but I've tried moving that, and it doesn't seem to do anything.
Can any 286 experts guide me to the right solution?
