SUMMARY: Error Message question

From: Aline H. Runde - MicroModule Systems (
Date: Wed Jan 12 1994 - 02:41:46 CST

Most managers said there is a problem with the memory module U312. The cheaper
way is that I may need to reseat it first before replacing it. But since it
is transient, I don't have to worry about it until I see that error message
repeating again and again.

Special thanks to Lars-Peter who sent me the picture of the SS2 board with
the chips location and Claus Assmann who pointed me to the archive site
"" to get the memory check summary. If any of you
happened to have the summary of the memory check info, would you please mail
it to me.

Thanks so much to all listed below, and I'm truly sorry if I miss any.
