   Compaq uses the Western Digital hard disk controller board, or so I hear.

   If you are asking about the Deskpro 286, it has NO memory on the mother
board.  There is a memory board plugged into one of the slots.  It has
128K in funny shaped chips on two small soldered-in daughter boards on
that memory board, and space for 512K of 64K RAM or 2 Mb. of 256K RAM,
depending on how you set a jumper.  Good deal, actually.

   The "80286-based Products Technical Reference Guide" is very good
(no bios listings, though).  The part number appears to be 102786-001.
It covers both the portable 286 and the Deskpro 286, but not (at least
when I got it) the Portable II.
