This is a last ditch effort, before I go out and replace my motherboard. I just added four more meg to my (generic Taiwan) 386SX motherboard, bringing it to a total of eight meg. The machine boots, memory test finds no errors, but both my protected mode operating systems, OS/2 1.1 and ESIX 3.2.C, crash. Good old M'soft provides the wonderfully intuitive "Parity Error ????", while ESIX says "PANIC: Parity Error on Motherboard" followed by a dump message. By taking the two SIMMs out of the fourth bank, everything works ok. I swapped all eight SIMMs around in the first three banks, so I know they're all good. I only get the parity error when I plug SIMMs into the fourth bank. Anyone have any thoughts? -- Kaleb Keithley Jet Propeller Labs kaleb@thyme.jpl.nasa.gov "So that's what an invisible barrier looks like!"
