Installing on a IBM PC320 Server

check out this page:

Before you install and configure FreeBSD on your system, there is an 
important subject that you should be aware of, especially if you have 
multiple hard drives.

In a PC running a BIOS-dependent operating system such as MS-DOS or 
Microsoft Windows, the BIOS is able to abstract the normal disk drive 
order, and the operating system goes along with the change. This allows the 
user to boot from a disk drive other than the so-called ``primary master''.

A user who is accustomed to taking advantage of these features may become 
surprised when the results with FreeBSD are not as expected. FreeBSD does 
not use the BIOS, and does not know the ``logical BIOS drive mapping''. 
This can lead to very perplexing situations, especially when drives are 
physically identical in geometry, and have also been made as data clones of 
one another.

When using FreeBSD, always restore the BIOS to natural drive numbering 
before installing FreeBSD, and then leave it that way. If you need to 
switch drives around, then do so, but do it the hard way, and open the case 
and move the jumpers and cables.

hope this helps,
