I don't know if it is something particular to rh9, or rh or grub or what. Hence the questions. I have run out of permutations for labeling where root is on hd2. (or alternatively hd1 when installing OS on hd2 and trying to boot up hd1) i guess i just have not made that clear? I did see one post on your list for similar problem...but there was either no resolution (just a question in response) or the resolution didn't fit this particular prob, i don't remember... thanks for any further info on the strange boot access problem... > Okay, here is an example from the grub shell (running under linux, > where kernel & rootfs is on /dev/hda7 on my computer), but you > need to do this from the *real* grub bootloader on your computer, > > grub> root (hd<TAB> > Possible disks are: hd0 hd1 hd2 > > grub> root (hd0,<TAB> > Possible partitions are: > Partition num: 0, Filesystem type is fat, partition type 0x6 > Partition num: 2, [BSD sub-partitions immediately follow] > BSD Partition num: 'a', Filesystem type is ffs, partition type 0xa9 > BSD Partition num: 'b', Filesystem type unknown, partition type 0xa9 > BSD Partition num: 'e', Filesystem type is fat, partition type 0xa9 > BSD Partition num: 'f', Filesystem type is ext2fs, partition type 0xa9 > BSD Partition num: 'g', Filesystem type unknown, partition type 0xa9 > BSD Partition num: 'h', Filesystem type is ext2fs, partition type 0xa9 > BSD Partition num: 'i', Filesystem type is ext2fs, partition type 0xa9 > BSD Partition num: 'j', Filesystem type is ext2fs, partition type 0xa9 > BSD Partition num: 'k', Filesystem type is ext2fs, partition type 0xa9 > Partition num: 3, Filesystem type is ext2fs, partition type 0x83 > Partition num: 4, Filesystem type unknown, partition type 0x82 > Partition num: 5, Filesystem type is ext2fs, partition type 0x83 > Partition num: 6, Filesystem type is ext2fs, partition type 0x83 > Partition num: 7, Filesystem type is ext2fs, partition type 0x83 > Partition num: 8, Filesystem type is ext2fs, partition type 0x83 > > grub> root (hd0,6)<ENTER> > Filesystem type is ext2fs, partition type 0x83 > > grub> kernel /boot/vmlinuz-2.4.2<TAB> > Possible files are: vmlinuz-2.4.21-4 vmlinuz-2.4.22-2 > > grub> help<ENTER> > blocklist FILE boot > cat FILE chainloader [--force] FILE > clear color NORMAL [HIGHLIGHT] > configfile FILE device DRIVE DEVICE > displayapm displaymem > find FILENAME geometry DRIVE [CYLINDER HEAD SECTOR [ > halt [--no-apm] help [--all] [PATTERN ...] > hide PARTITION initrd FILE [ARG ...] > kernel [--no-mem-option] [--type=TYPE] makeactive > map TO_DRIVE FROM_DRIVE md5crypt > module FILE [ARG ...] modulenounzip FILE [ARG ...] > pager [FLAG] partnew PART TYPE START LEN > parttype PART TYPE quit > reboot root [DEVICE [HDBIAS]] > rootnoverify [DEVICE [HDBIAS]] serial [--unit=UNIT] [--port=PORT] [-- > setkey [TO_KEY FROM_KEY] setup [--prefix=DIR] [--stage2=STAGE2_ > terminal [--dumb] [--no-echo] [--no-ed terminfo [--name=NAME --cursor-address > testvbe MODE unhide PARTITION > uppermem KBYTES vbeprobe [MODE] > > The TAB key is your friend, so is the "find" and "geometry" commands. > > grub> geometry (hd2)<ENTER> > drive 0x82: C/H/S = 527/255/63, The number of sectors = 8467200, /dev/sdb > Partition num: 1, [BSD sub-partitions immediately follow] > BSD Partition num: 'a', Filesystem type is ffs, partition type 0xa5 > BSD Partition num: 'b', Filesystem type is ext2fs, partition type 0xa5 > BSD Partition num: 'e', Filesystem type is ext2fs, partition type 0xa5 > BSD Partition num: 'f', Filesystem type unknown, partition type 0xa5 > BSD Partition num: 'g', Filesystem type is ext2fs, partition type 0xa5 > BSD Partition num: 'h', Filesystem type is ext2fs, partition type 0xa5 > Partition num: 2, Filesystem type is ext2fs, partition type 0x83 > Partition num: 3, Filesystem type is ext2fs, partition type 0x83 > Partition num: 4, Filesystem type unknown, partition type 0x82 > Partition num: 5, Filesystem type is ext2fs, partition type 0x83 > Partition num: 6, Filesystem type is ext2fs, partition type 0x83 > > Have you read the grub info docs yet? > > -- > Jeff Sheinberg > _______________________________________________ Bug-grub mailing list [EMAIL PROTECTED] http://mail.gnu.org/mailman/listinfo/bug-grub
