[comp.sys.ibm.pc.hardware] Parity Errors

rcharbon@athena.mit.edu (Ray Charbonneau) (01/30/91)

On an IBM XT with 640K on the 256-640K motherboard I get the following:

Parity Check 1
9C 220

Unfortunately, this doesn't match with any of the parity error documentation
I've got.  Anyone know what these numbers mean?

Please E-mail responses and I'll post.
Thanks!

MIT and the Library Systems Office are glad that I'm posting my opinions
here so that they don't have to listen to them anymore.

We have an AST 286, with 1 Meg Ram. It has been getting parity errors
quite regularly, but not in any identifiable pattern. I believe parity
errors are caused by flaky DRAMs, or flaky connections to the RAM.

Are parity errors caused exclusively by the RAM chips? If so then I'd
be pretty safe replacing all the ram chips. The error pops up at segment 
8000.

On another note, does anyone know how to contact AST? ie 1 800 number or
fax.

Thanks,
