- My son has the exact same setup and problem you describe. We were
- able to get the diagnostics to fail (report errors and not guru) by
- addressing the 32 bit memory high. That way the test isn't actually
- executing from the suspect memory.
-
- We have not been able to fix problem though. We swapped the memory
- chips around on the board expecting a different error but the failures
- were always the same. I suspect that his problem is one of the driver
- ICs and not a bad memory chip. Your luck may be better.
