With many newer BIOS' there is an option in the BIOS to pick which drive to
boot from. You would have to go into the BIOS and change this each time you
want to boot from a different drive. If you have another installation of XP
on the master drive you could also edit the boot.ini file to add a boot menu
with the Windows on the slave drive as one of the options.

Yes, Kerry, I can pick which drive to boot to, and I used to do
just as you said, with my old PC. Doing the same thing with
this new machine, it starts of headed for the Slave and ends
up booting to the Master. If I set it to boot to the Slave,
and interrupt with F8 and select Safe Mode, it starts doing
the right thing (i.e., I see the full page list of files that
I always see for Safe Mode), but then it goes black and starts
over.

And I never have more than one installation of operating systems
on one physical hard drive; several drive images from various
dates, but never a second OS.
