Dell PowerEdge 2900: raid/Linux conversion logistics

Gus asked:

I’ve got a Dell PowerEdge 2900 (currently running windows) that I want to convert into a Linux server. But, it’s got a hardware RAID controller and I want to be sure I don’t destroy the configuration utility. When it boots, I can currently (when prompted) hit CTRL-R and it launches a raid config utility:

PERC 5/i Integrated BIOS Configuration Utility 1.02-0007

Where is this utility located (Disk vs BIOS)? If it’s on disk, what’s the best way to keep that functionality available post-linux install?

My answer:

The pre-boot RAID BIOS is embedded into the RAID card. It’s completely OS-independent.
