Dual booting Windows 2000/OpenBSD 3.0

["Michael Greenberg" <greenberg_(_at_)_nji_(_dot_)_com>]

I'm trying to set up a W2K/OBSD3 dual-booter, and I'm not sure of 
what to do partition-wise.  I'm running an Athlon XP (with 512 
megabytes of sweet, delicious, DDR RAM) on a Biostar board (yeah, 
it's not great), so I think that my BIOS is okay with booting from just 
about anywhere (if not, correction would be greatly appreciated).

I'm trying to lay it onto a 40GB drive, and the way the documents 
seem to point, I would do that following:

1) Install OpenBSD into 5GB worth of space (that's all I want).
2) Do the dd if=/dev/wd0a... as per the FAQ, putting openbsd.pbr 
onto an MS-DOS formatted disk.
3) Install Windows 2000 onto the remaining 35GB (writing over the 
OpenBSD MBR).
4) Copy the OpenBSD PBR, fix boot.ini, and we're done.

I suspect, though, that this is not all.  Is there a way to install 
OpenBSD so that it expects this, and I don't have to worry about 
messy overwrites, etc?  There's no data, of course, so I can retry as 
many times as I can tolerate it.

Any tips, experience, or witty and life-affirming anecdotes?

Thanks,
Mike.
