As slice 3 is above cylinder 1023, F3 shouldn't work, but the other
two should. Does F1 get you to Windows? If not, I'd suspect your
BIOS may be using a different geometry than 16 heads, 63 sectors.
If just F2 doesn't work, the problem may be the FreeBSD boot code
is not installed correctly. To try correcting that, do the
equivalent of a
disklabel -B -b /boot/boot1 -s /boot/boot2 ${DRIVE}
(making any adjustments needed on account of the fixit option).
If that doesn't have any effect, send me the output of the
following commands and I'll take a look:
fdisk ${DRIVE}
disklabel ${DRIVE}
dd if=/dev/r${DRIVE} count=1
dd if=/dev/r${DRIVE}${SLICE} count=17
(In the first dd command, we need the first sector of the disk; in the
second, we need the first seventeen sectors of the FreeBSD slice that
contains the / partition.)
