Grub and BSD-style partition

[Arnaud Lacombe]

Hi,

I try to use grub on NetBSD. It was working without any problem until I
change hard drive and re-setup my OSs. In fact, the drive contain 3 OSs:
 - a windows (at the beginning)
 - a freebsd 
 - a netbsd

I'm using Grub 0.97 from netbsd's pkgsrc. It fails to read stage1
correctly, here is the message returned by grub:

grub> dump (hd0,h)/grub/stage1 /tmp/grub-install.img.12734
Error 22: No such partition

NetBSD is my main OS and I wish to install grub from it but it seems
that grub is unable to access the partition. Here is my partition
scheme:

# fdisk wd0
[...]

The root of netbsd is on wd0h. Grub is unable to access partition >=
wd0g. It seems to break somewhere in real_open_partition() in
stage2/disk_io.c. I didn't dig deeper by now.

does anyone have any idea about how I can install grub correctly ?
