I would appreciate any information about *how* to do a thorough job of
checking RAM in a PC, XT, and/or AT -- including at least the following
aspects:
==> Localizing parity errors.
==> Determining refresh time for individual chips.
==> Detecting address translation problems (i.e., writing in one
address and having the data pop up at another address).
I have picked up a few RAM testing programs from various sources, but:
(1) none of them come with source; and
(2) I have a 286 motherboard (with XT bus) that has a special
way of accessing the top 384K of its 1 meg worth of on-board
RAM, and I want to be able to test this extra RAM (something
the "stock" RAM testing software obviously won't do).
I'm reasonably comfortable with C and assembler, and am not averse to
writing my own RAM tester. Who knows, I may even end up with something
worth posting.
