Hi,

actually the "error report" is correct, on PPC platforms there is no BIOS but
the hardware is configured via Open Firmware. I've been getting this message
for years, it's totally harmless.

By the way: Do you have AGP mode working stable on the Mac Mini G4 ? I've been
trying to do that for years with no success :-(
