Has anyone been successful in getting FreeBSD running on the Intel
AL440LX motherboard?  We've tried both 2.1 and 3.0 and both have
problems.  Booting from floppy works fine, but booting from the scsi
drive (after install) either gives "read error" in 2.1 or no message
at all under 3.0 immediately following the normal bios stuff.

Seems to be something related to the MBR since it will boot fine from
the drive at the floppy boot prompt (i.e. sd(0,1)kernel with floppy
boot).  In both cases the hard drive was formatted to not use slices
(dedicate entire drive to FreeBSD), so no boot manager is being used.
Bios setting for the motherboard and adaptec are normal (i.e. similar
settings on other combos have worked fine).  In addition various bios
changes were made with no effect.  Basically have run out of things to
try.  Any ideas, or things to try?


dmesg output (with 3.0) is:
