I have an all-SCSI system with FreeBSD 6.3 on one disk and 7.0 on the
other. It booted using GRUB and worked OK.
I installed Mandriva Linux on the disk that had 7.0 on it (replacing 7.0)
The setup now is:
SCSI ID 15 73GB /dev/sda - running FreeBSD
SCSI ID 14 36GB /dev/sdb - Mandriva
The device names above are as reported by Mandriva when doing the install.
Mandriva installed OK onto the 36GB HDD and wrote this menu.lst:
Code:
timeout 10
color black/cyan yellow/cyan
gfxmenu (hd0,0)/boot/gfxmenu
default 0
title linux
kernel (hd0,0)/boot/vmlinuz BOOT_IMAGE=linux
root=UUID=77a15e0a-b9f5-46ab-8236-886418dbbfd8 resume=/dev/sdb5
splash=silent vga=788
initrd (hd0,0)/boot/initrd.img
title linux-nonfb
kernel (hd0,0)/boot/vmlinuz BOOT_IMAGE=linux-nonfb
root=UUID=77a15e0a-b9f5-46ab-8236-886418dbbfd8 resume=/dev/sdb5
initrd (hd0,0)/boot/initrd.img
title failsafe
kernel (hd0,0)/boot/vmlinuz BOOT_IMAGE=failsafe
root=UUID=77a15e0a-b9f5-46ab-8236-886418dbbfd8 failsafe
initrd (hd0,0)/boot/initrd.img
Note that it has used hd0 even though the disk is /dev/sdb (which
implies the second disk).
The problem is that when it boots the Adaptec SCSI BIOS searches for
bootable drives from the highest SCSI ID downwards. Since the 73GB
(FreeBSD) disk is id 15 it boots from that. That disk also has GRUB
installed with an entry for FreeBSD which is also hd0. The FreeBSD entry
works.
Because the disks are seen by the SCSI BIOS as id 15 first, id 14
second, id 14 - the disk with Mandriva installed, is hd1 so I copied the
Mandriva menu.lst file into the one on the FreeBSD partition and edited
hd0 to hd1 (for both the lernel and initrd lines) but Mandriva won't
boot, I get
Error 2: Bad File or Directory type
In fact, the FreeBSD GRUB seems unable to read the Linux disk - it knows
it's there, but can't access anything on it.
I've tried numerous things as suggested on the Mandriva forums but
nothing works:
grub> root (hd0,0,a)
Filesystem type is ufs2, partition type is 0xa5
grub> cat /boot/grub/device.map
(fd0) /dev/fd0
(hd0) /dev/da0
(hd1) /dev/da1
grub> root (hd1,0)
Filesystem type is ext2, partition type is 0x83
grub> cat /boot/grub/device.map
Error 2: Bad file or directory type
grub> root (hd <TAB>
Possible disks are: hd0 hd1
grub> root (hd1, <TAB>
Possible partitions are:
Partition num: 0, Filesystem type is ext2fs, partition type 0x83
Partition num: 4, Filesystem type is unknown, partition type 0x82
Partition num: 5, Filesystem type is ext2fs, partition type 0x83
grub> root (hd0, <TAB>
Possible partitions are:
Partition num: 0, [BSD sub-partitions immediately follow]
BSD Partition num: 'a', Filesystem type is ufs2, partition type 0xa5
BSD Partition num: 'b', Filesystem type is unknown, partition
type 0xa5
BSD Partition num: 'd', Filesystem type is ufs2, partition type 0xa5
BSD Partition num: 'e', Filesystem type is ufs2, partition type 0xa5
BSD Partition num: 'f', Filesystem type is ufs2, partition type 0xa5
Can anyone suggest how to make this work? The root of the problem is
that both OSes think their disk is hd0.
Regards,
Mark
