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.

I just installed grub from ports and duplicated your test and it works fine. I'd start by checking your installation and making sure you don't have any other grubs in your path. Some of the grubs that ship with Linux distros do not support ufs. Do a find/locate on grub to see what turns up. Do a which grub, you should get /usr/local/sbin/grub. If not, issue /usr/local/sbin/grub from a command prompt and duplicate your test. If that's broken, make sure your ports tree is up to date, make sure /usr/ports/devel/autoconf259 /usr/ports/devel/automake19 /usr/ports/devel/gmake are up to date (grub's build dependancies) then
deinstall, clean, and reintsall the grub port.
