I'vetried using the MPBIOS option as well as the MPACPI option respectively with the same result.  I used the cpu* at mainbus? option both times and the ioapic* at mainbus? apid? option when I used MPACPI.  These are all set in the "GENERIC" config file (I renamed mine AOXOMOXOA) and commented out of GENERIC.MP (which I renamed AOXOMOXOA.MP).  I ftp'd the source tree before configuring, built the tools, etc. and did ./ kernel=AOXOMOXOA.MP from /usr/src - which completes without errors.  I rename and mv the new kernel to /, renaming the old one to netbsd.old and reboot.  The dmesg output below is what I get regardless of whether I use MPBIOS or MPACPI.

It looks like you have a quirky board, given that both FreeBSD and NetBSD
have trouble kicking the second CPU into action. Did the CPU spin up
properly with FreeBSD-5.0-DP1? I don't see any recent changed in the
FreeBSD tree that would indicate a fix to make this go.

Do you know if other operating systems work with the second CPU?
