grub & freebsd booting problem

**l8forwork** · 06-12-2005

loaded a third harddrive with bsd from cd with mbr but no loader...went in linux to /boot/grub/ and edited in
title freebsd
root (hde,0)
table=/dev/hde
label=freebsd

i'm lost... got the bsd book and looked at man on line, both talk about lilo ... forum notes say grub'l work fine... i'm lost

I think you forgot the "kernel /boot/loader" line.

A standard grub entry for FreeBSD (4.11 anyway) looks something like this:

Code:

title FreeBSD
  root &#40;hd0,0,a&#41;
  kernel /boot/loader

First hard drive (hd0), first slice (0) in my case. I am not sure if/how this has changed in 5.x.

I think that's pretty much like 5.x, here's mine for freebsd 5.4:

Code:

title FreeBSD 5.4
root &#40;hd0,1,a&#41;
kernel /boot/loader
boot

found all this on grub site:
GRUB identifies hard disks by "hd" and floppy disks as "fd" followed by a number starting from 0. In commands, the disk references are always enclosed in parentheses, thus the first hard disk would be referenced as (hd0). Disk partitions are separated from the hard disk by a comma and identified as 0 - 3 for the primary partitions and 4 and up for partitions inside an extended partition. FreeBSD numbers its slices from 1 to 4, and Linux its partitions from 1 to 16, rather than starting at 0, so you'll need to reduce a FreeBSD slice or Linux partition number by one to get the right disk partition number. If the partition is a BSD disklabel "subpartition" in GRUBs terminology, these are separated by a comma and start from 'a'. Thus (hd0,2,a) would point to FreeBSD's /dev/ad0s3a or the 'a' partition of the third slice on the first hard disk.

but still no boot... third drive is on a ultra66 controler card grub error says
error parsing number????

pulled the other two drive out loaded bsd on prim master channel it comes up!!! put the other two back in parsing error

my code:
title freebsd-5.0
root (hde,0,a)
kernel /boot/loader/

still lost!!!!!!!!!!!!!!

For this line

Code:

root &#40;hde,0,a&#41;

Why hde? If it is third physical drive, shouldn't it be hd2? Maybe that is why it is throwing a number parsing error; e is not a number.

unless they've fixed grub, you need to chainload fbsd if you're using UFS2 as your filesystem...

Code:

rootnoverify &#40;hd0,0,a&#41;
chainloader +1

grub found boot for bsd

Code:

title freebsd-5.0
root &#40;hd2,0,a&#41;
kernel /boot/loader

was using e as that is what linux's fdisk called it hde

But linux and grub have different partition "names"... what's in linux called "hda" is under grub called (hd0) and "hdb" is (hd1) and so forth...
