You're booting the wrong kernel. Do a buildkernel + installkernel now,
reboot the system, and check that the kernel's build date has incremented.
Also watch the loader output and make sure someone hasn't overridden the
kernel name in loader.conf.

This appears to be the latest BIOS. Some Compaq systems are known to
generate bogus MPTables and such when configured to run Windows. You might
poke around the BIOS Setup and see if there is an "OS Type" field that can
be set to "SCO UNIX" or "Other" (not in PnP setup probably).

Good idea :)
