grub doesn't know ufs filesystem

[Roberto Nunnari]

Hello list.

Please also reply to my mailbox, as I'm not on the list.
Thank you.

I have a old grub floppy that I use time to time to
boot/recover pc with different OS.. Today I wanted to
boot a freebsd 5.3-RELEASE-p23 box, but to my surprise
grub reported:

Filesystem type unknown, partition type 0xa5

and thus cannot mount /boot/loader

So I thought I'd make a grub floppy with a recent version,
but even with version 0.97 things won't change..

# cd /usr/ports/sysutils/grub
# make install
# grub
  [ Minimal BASH-like line editing is supported.  For the first word, TAB
    lists possible command completions.  Anywhere else TAB lists the 
possible
    completions of a device/filename. ]

grub> root (hd0,0,a)
  Filesystem type unknown, partition type 0xa5

grub> kernel /boot/loader

Error 17: Cannot mount selected partition

grub> root (hd0, <TAB>
  Possible partitions are:
    Partition num: 0, [BSD sub-partitions immediately follow]
      BSD Partition num: 'a',  Filesystem type unknown, partition type 0xa5
      BSD Partition num: 'b',  Filesystem type unknown, partition type 0xa5
      BSD Partition num: 'd',  Filesystem type unknown, partition type 0xa5
      BSD Partition num: 'e',  Filesystem type unknown, partition type 0xa5
      BSD Partition num: 'f',  Filesystem type unknown, partition type 0xa5

grub> quit

# mount
/dev/ad0s1a on / (ufs, local, soft-updates)
devfs on /dev (devfs, local)
/dev/ad0s1e on /tmp (ufs, local, soft-updates)
/dev/ad0s1f on /usr (ufs, local, soft-updates)
/dev/ad0s1d on /var (ufs, local, soft-updates)
linprocfs on /usr/compat/linux/proc (linprocfs, local)
devfs on /var/named/dev (devfs, local)

Any hint/thought/advice?

Best regards.
