When i installed my intel above board 286/ps into my 386 machine, i had a bad
memory chip on it (unknown to me at the time, of course (:-(..). I ran the
intel diagnostics (testab.exe) on the silly thing for >100 times w/o a single
error being detected.
I later talked to an intel tech who admitted that the intel diagnostics were
(i'm paraphrasing slightly here:) "rather lame." He admitted that the
diagnostics did not really test extended memory!! I guess 'cause dos doesn't
use it very well (the extended memory, that is) that memory wasn't really
required to be tested.
I also talked to my wholesaler's tech, who stated that he had seen (memory)
chips completely removed from the board and the diagnostic still ran w/o one
error!!!!!
Thats amazing.
