Dual-boot does not work with GRUB

[Jaroslaw Nozderko]

FreeBSD 5.1-RELEASE
RedHat Linux 9.0


Hi,

 I have such problem: RedHat Linux 9.0 (Shrike) and FreeBSD 5.1-RELEASE
together. I'd like to have working dual-boot with GRUB.

# fdisk -l

Disk /dev/hda: 120.0 GB, 120034123776 bytes
255 heads, 63 sectors/track, 14593 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot    Start       End    Blocks   Id  System
/dev/hda1             1        65    522081   83  Linux
/dev/hda2            66      3889  30716280   83  Linux
/dev/hda3   *      3890      7713  30716280   a5  FreeBSD
/dev/hda4          7714     14593  55263600    f  Win95 Ext'd (LBA)
/dev/hda5          7714     10263  20482843+  83  Linux
/dev/hda6         10264     11793  12289693+  83  Linux
/dev/hda7         11794     13068  10241406   83  Linux
/dev/hda8         13069     14088   8193118+  83  Linux
/dev/hda9         14089     14219   1052226   82  Linux swap
/dev/hda10        14220     14350   1052226   83  Linux

FreeBSD partition is visible as hda3 under Linux and ad0s3 under
FreeBSD. It has 3 slices: 

swap     1 GB    ad0s3b
/home1   1 GB    ad0s3d
/       28 GB    ad0s3a

After reading GRUB documentation, I've prepared the following
entry in grub.conf:

# FreeBSD
title FreeBSD 5.1-RELEASE
	root (hd0,2,a)
	kernel /boot/loader

Despite GRUB doc, I'm not sure I understand this format.
According to

http://www.gnu.org/software/grub/manual/html_node/Configuration.html#Configuration

(hd0,2,a) means "partition of the third PC slice of the first hard
disk". Is "a" a slice symbol and "2" is a partition number (starting
with 0) on hd0 ?

I've got the following error:

Filesystem type unknown, partition type 0xa5
Error 17: Cannot mount selected partition

Does GRUB have some problems with FreeBSD partition ?
This is probably some stupid mistake.

Could anyone give me some advice ?

Thanks for any help,
Jarek

Hi,
    I to have a multi boot system with linux and freebsd and windows.
GRUB is my boot loader.
I did not chain load FreeBSD.

This is my menu file for GRUB
default=1
timeout=10
splashimage=(hd0,4)/grub/splash.xpm.gz
title Red Hat Linux 9 (2.4.20-8)
	root (hd0,4)
	kernel /vmlinuz-2.4.20-8 ro root=LABEL=/
	initrd /initrd-2.4.20-8.img
title Windows 2000
	rootnoverify (hd0,0)
	chainloader +1
title FreeBSD 4.8
	root (hd0,3,a)
	kernel /boot/loader

And my fdisk -l
   Device Boot    Start       End    Blocks   Id  System
/dev/hda1             1       892   7164958+   7  HPFS/NTFS
/dev/hda2           893       956    514080    b  Win95 FAT32
/dev/hda3           957      2522  12578895    5  Extended
/dev/hda4   *      2523      4865  18820147+  a5  FreeBSD
/dev/hda5           957       969    104391   83  Linux
/dev/hda6           970      2457  11952328+  83  Linux
/dev/hda7          2458      2522    522081   82  Linux swap

This works fine for me.
I to am a beginner and still gathering info

Hope it helps
