How to boot PC BSD from GRUB

[valos]

Hi,

I have two SATA hard drives on my machine, on the first one I have WinXP and Ubuntu 7.04 and I have installed PC BSD on the first partition of the second one.

I did not install the boot loader for PC BSD because I want to boot it from GRUB.

What changes do I have to do to GRUB config files in order to be able boot PC BSD?

From Ubuntu i did a fdisk -l:

Disk /dev/sda: 82.3 GB, 82348277760 bytes
255 heads, 63 sectors/track, 10011 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System
/dev/sda1 1 2550 20482528+ a5 FreeBSD
Partition 1 does not end on cylinder boundary.
/dev/sda2 2551 5100 20482875 6 FAT16
/dev/sda3 5101 9689 36861142+ 6 FAT16
/dev/sda4 9690 10011 2586465 6 FAT16

Disk /dev/sdb: 400.0 GB, 400088457216 bytes
240 heads, 63 sectors/track, 51681 cylinders
Units = cylinders of 15120 * 512 = 7741440 bytes

Device Boot Start End Blocks Id System
/dev/sdb1 * 1 13545 102400168+ 7 HPFS/NTFS
/dev/sdb2 13546 46053 245760480 7 HPFS/NTFS
/dev/sdb3 46054 48627 19459440 83 Linux
/dev/sdb4 48628 51681 23088209 f W95 Ext'd (LBA)

/dev/sdb6 51405 51681 2094088+ 82 Linux swap / Solaris

And this is grub's config file:

kernel /boot/vmlinuz-2.6.20-16-generic root=UUID=7b09c105-9ad5-4e2d-b90d-1ffc113f4344 ro quiet splash noapic nolapic pci=assign-busses
