Thanks, I tried to look at the options in the BIOS. I can enable or 
disable the SATA disks.

setup A)

Master: FreeBSD
Slave:  XP

If I disable the master disk I boot XP fine - although the disk is slave.

If I enable both, I get the FreeBSD boot manager with the FreeBSD as 
master disk with two options:

F1 FreeBSD
F5 Disk 1

setup B)

Master: XP
Slave:  FreeBSD

If I enable both, I boot straight into XP. I cannot enable both and 
select to boot the slave disk.

If I disable the master disk, I get FreeBSD boot manager, but this does 
not see the master disk with XP giving me no option to boot it.

So, it appears that I have to install the FreeBSD bootmanager (or some 
other multiboot boot manager) on the XP disk?

It's been more than 5 years since I had a multiboot, so I'd like to know 
how I can do this and still get back to the original settings. How can I 
backup the existing MBR?

Thanks, Erik
