O.K. on the SMP error. I am still curious because I only
have one Pentium III cpu (single core). Should I change
the APIC setting in the BIOS?
Note: The ERR count appears to be 3 after IPL and stays
at this number. It does not increase, so I don't worry.
If I change the BIOS setting from "APIC" to "PIC" I then
get 6 ERR instead of 3 ERR. Therefore I leave it at "APIC".
