On a Dell 600SC box with SCSI RAID, purchased in May 2003, Dell was 
quite anxious to make sure I received new firmware plus new Linux 
drivers. So you may check with them for firmware, though obviously the 
drivers won't do you any good.

Which brings up an unfortunate situation when running unsupported 
software. When Dell updates the Linux driver to fix file corruption 
problmes, how do the changes make it into the FreeBSD driver? Usually 
the answer is, "they don't".

Also, unfortunately I don't have easy access to the box, but I think 
it's running something very similar to PERC3. (PowerEdge RAID controller).
