Make sure you've got boot0 on the primary master (assuming IDE) or da0 (SCSI) and on no other drives. Booting from one boot manager on the BIOS boot disk to boot0 on another drive hasn't worked well in my experience. Also, make sure FreeBSD's idea of your drive geometry matches what the BIOS thinks. Posting disklabel and 'fdisk -s' output might help. (The fixit CD is your friend here.)
