[comp.sys.ibm.pc.misc] What does message "I/O card parity

twg0214@uxa.cso.uiuc.edu (09/19/90)

I had a similar message but at a different address in my Gataway 2000 386/33
after I added 4Mb RAM. What was interesting was that the message was always
there when booting OS/2, never under DOS 4.01, and there was a single memory
error indicated by the memory diagnostics. After removing the suspected memory
chip, the diagonostic error disappear but OS/2 kept complaining at boot-up.
OS/2 alway ran fine afterwards. After getting a replacement memory board, I 
discovered that one of the extra chips was inserted upside down. After putting
it back, everything was just fine. However, I lost my faith in DOS ability
to discover parity errors. Perhaps it does it good only up to 640k!
