Never thought about the BIOS but if he installed the FreeBSD Boot
Manager on both drives, then all he has to do to boot the second drive is
he has to hit the key to select the second drive when the Boot Manager
shows up prior to FreeBSD booting. The switching cables or even replacing
the original drive with the second drive is really only if the main drive
dies or if you wanted to use a different drive like greater capacity,
faster, etc or you didn't like the brandname of the drive for some reason.
