Hi,

I hit upon this procedure through many trial and error attempts,
so I thought posting it here will be a good way to document it. Also,
most of the substeps are well documented on websites, help documents.

What I wanted to do:
I had a pc running Windows 98 , XP. I wanted to add OpenBSD (3.5)
to it. This was easy. I wanted to boot all 3 using GRUB (not
straightforward for me). I did not want to install linux just to write
GRUB to my hdd.

Of course, if you are ready to do this, I wont bore you with
warnings or copylefting.

(1) In OpenBSD download, compile, install GRUB. (I tried GRUB 2,
but it complained about a missing library, which I tried to install
using pkg_add - to no avail). On my installation, files were installed
to /usr/local/lib/grub/i386-unknown . I also put my menu.lst file
here.

(2) Use the floppy install documentation to make a GRUB bootable
floppy. grub-install didnt work for me - to install on my hdd. if
grub-install works for you - lucky you.

(3) Use the floppy to boot to the grub command shell.

(4) Since my grub files were in /usr (BSD partition g) (and this
was on my first drive, first parition) I mounted g as root
> root (hd0,0,g)
> setup --prefix=/local/lib/grub/i386-unknown/ (hd0)

ta da
