Hi Micah and Harley, Thanks for your answer. Humm.. I don't have any other grub on my path, and running which returns: # which grub /usr/local/sbin/grub The ports were updated quite recently.. in occasion of last update world. I did some more testing.. the strange thing is that I use the same grub boot floppy and the results are ok on the newly installed freebsd boxes, while on the two that are already installed the results are bad.. test 1: ======= - made a grub floppy - boot the existing FreeBSD boxes (2 boxes) from grub floppy result --> grub doesn't know the ufs filesystem test 2: ======= - installed a brand new FreeBSD 5-3-RELEASE with default partitioning on the whole disk on a separate pc - boot with grub floppy result --> grub recognizes the ufs filesystem test 3: ======= - same as test2, but / root has now soft-updates option - boot with grub floppy result --> grub recognizes the ufs filesystem test 4: ======= - same as test2, but partitioning done with partition magic as was done on the computers of test1 - boot with grub floppy result --> grub recognizes the ufs filesystem All that seams to point out that there's something wrong with the existing FreeBSD boxes.. but What? I must say that both boxes had all filesystem dumped and restored after repartitioning for permitting the use of dumping software such as ghost (that didn't like the partitioning done by freebsd during installation..) Any more ideas? Harley D.
