Hi,
OpenBSD 5.0 fails to boot on older servers (generally Pentium III and
under) with the ServerWorks chipset. MSI should not try to be used on
these.
I created the following patch. The chipsets identified are educated
guesses based on Google search and sequence number, but there's not a
great way to cross reference and make sure all are included and the
PCI names don't match up to the marketing name. Anyway, this is a
good enough start and should make people happy as their systems will
boot again.
Regards,
Kevin Bowling
