 I see a related problem with FreeBSD-6.1: an initial install seems to set
 the MBR with -o nopacket, but explicitly doing "boot0cfg -Bv ad0" correctly
 sets -o packet in the MBR.
 
 I have not observed this directly in the MBR, but is based on the following
 sequence:
 
 - divide a 40GB HD into two primary partitions
 - install FreeBSD in the first 20GB, with its bootloader in the MBR
 - install OpenBSD in the second 20GB
 - the FreeBSD bootloader then offers
 
   F1 FreeBSD
   F2 BSD
 
   but F2 just beeps (i.e. cannot boot OpenBSD)
 
 - booting into FreeBSD and issuing "boot0cfg -Bv ad0" fixes the problem.
 
 Therefore my guess is that the initial installation of the MBR is setting -o
 nopacket, even though boot0cfg has -o packet as its default.
