RE: Dual Booting XP and Obsd

["COTTLE,DAVE (HP-France,ex2)" <david_cottle@hp.com>]

in principle i disagree; ntldr does what it does simply and well. but
getting the bit for the boot sector is difficult (not due to win32 though,
try doing it for any OS. 

ignoring the XP aspect, which shouldn't be too different unless you
foolishly opted for dynamic disks (you didnt....)

create your OBSD partition using the relevant win32 disk partition manager
(windisk/logical disk mgr)
then use dskprobe from the reskit to make it A6 and the active partition

then boot OBSD and install to your newly active partition
reset the active partition from OBSD or whatever tool (bootable FDISK
floppy) back to win32
if you have a shared FAT partition do this with dd ref the docs for making a
kernel boot floppy
reboot into win32
use dskprobe to grab the OBSD boot sector off if you didnt above
whap that into your alternative boot file in ntldr as per linux docs you
refer to
then it works happily (just like a bought one)
regards
dave

I'm doing it at home on one box, on two of my friends computers, and on a
IBM ThinkPad laptop too.

Long and the short of it is "forget trying to modify ntldr" - ntldr does
*not* handle OpenBSD easily - I've never got them playing together nicely.

More word of advice:
Install your MS OS onto FAT32... really. That way you can recover your files
when it crashes, and you can use that space from OpenBSD.
Put your BSD at the beginning of the drive...
After installing everything, boot from a DOS/Win95-98 boot floppy and use
OS-BS - it works a charm. There's no need to adjust the active partition ID.
Dual booting also works fine with BootMagic.
Early versions of XP summarily trash a type A6 partition... I haven't played
with the final release yet, but be careful. Your best bet is to get your
partitioning right and you FAT partition formatted before installing
anything.
Read all the docs you can get your hands on - there's a really good FAQ for
dual-booting Linux and OpenBSD that gives you good pointers for some of the
gotcha's you'll come across.
Have a calculator and a piece of paper handy... trust me.

Hey guys,
Anyone dual booting xp or 2k and obsd? I just got a
lappy, and I am afraid of trashing it, but I need to
keep windows for my cs class. If anyone has any
pertinent things that could save me time, trouble, or
turmoil, I welcome them with open arms. Also, I was
thinking of some kind of webpage where we could all
document working hardware setups with obsd and
reviews. I don't know. If it were made would there be
any interest in using it?
