as suggested in the docs in the internet I tried both with
=
=20
# fdisk -B -b /boot/boot0 ad0
fdisk: cannot open disk /dev/ad0: No such file or directory
and with
=
=20
# fdisk -B -b /boot/boot0 ad1
fdisk: cannot open disk /dev/ad1: No such file or directory
WHILST
my working /etc/fstab is, as I mentioned before:
# Device Mountpoint FStype Options Dump Pas=
s#
/dev/ad1s2b none swap sw 0 0
/dev/ad1s2a / ufs rw 1 1
/dev/ad0s1a /usr/local ufs rw 0 0
/dev/ad0s1d /var ufs rw 0 0
/dev/ad0s1e /tmp ufs rw 0 0
Why FreeBSD 5.4 cannot find /dev/ad0 and ad1?
What should I do? =20
A baffled and frustated Vittorio again
