> The Error is as follows: EDAC i5000 MC0: nonfatal errors > found 0=800. Your system is logging errors. That in itself is not good news but could be BIOS triggered I guess. The full EDAC dumped values it logs if this was a CPU error would be informative. If its logging a PCI error and you get just one it may be noise from boot and is ok > The system runs very very slow (I have a p3 that is faster > then this system is). First guess: BIOS memory tables are wrong. That shows up differently in Linux and Windows. Boot with mem=1G option (if you have > 1.2GB) and see if its suddenely faster. If so then you can either adjust the cached ram settings or use mem= to trim the BIOS uncached memory off. > There are no errors under Windows, and there are no errors > reported by Dell's diagnostic tools. Dell's tools are pretty basic and windows generally doesn't do much hardcore error checking. I don't think however your EDAC and slowness are neccessarily bits of the same bug (although they may both be crap BIOS) Alan
