I would like to try the AMD64 version of 3.9 on my office

care to get the boot manager (GRUB) on the MBR of the
correct disk.

XP has NTLDR. Install OpenBSD on free space on your drive.
Copy the PBR to C: under NT. Update C:\BOOT.INI. Mine looks
like this:

$ cat /ntfs/BOOT.INI
[boot loader]
timeout=5
default=C:\OPENBSD.PBR
[operating systems]
C:\OPENBSD.PBR="OpenBSD -- Secure by default"
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /fastdetect /NoExecute=OptIn

On power-up OpenBSD boots unless I specifically select XP.

See http://www.openbsd.org/faq/faq4.html#Multibooting for more info.

I've installed a number of BSD flavors including 3.9 and
don't recall a multiboot manager.

Does 3.9 have something similar to LILO or Grub?

Not that I've seen. When installing Open, it writes itself to the MBR.
Let it.

dd if=/dev/wd0c bs=512 count=1 of=/mnt/floppy
use the Windows install disk to 'R'epair an installation.
type 'fixmbr' and 'fixboot'

windows will boot by default.

copy file from the floppy to C:
update C:\boot.ini as described in the other post in this thread.


An alternative -- and works BEAUTIFULLY!!!!

lookup GAG - the Graphical Boot Manager
http://gag.sourceforge.net/

This thing is sweet -- the only limitation is that it uses the numeric
keys 1-9 (not zero) to define what partitions to boot. I've not had ANY
problems with it.

You write an image file to floppy disk. Once it's written, you can
install it on as many HDDs as you want.

You setup the OSs, including a picture, even with a default timer. It
claims to boot OS/2, Windows (all), Linux, Free/Open/NetBSD, SCO, BEoS,
Solaris, DragonflyBSD, and a couple more...

No problems at all.. love it.

Kudos to the author.
