I recently added a 8MB DIMM Parity module to by 755cx (for total of 16MB) and am getting error messages as follows: System Halted parity error detected The only way to restart the machine is to turn it off (CTRL-ALT-DEL won't work). This tends to happen when I am communicating. Any suggestions on what I should do? I have installed the latest BIOS from Sys 1.40 disks. Thanks, Joe Wilson jcwilso@ibm.net
