Hello experts.

I was getting a low battery message on my Poweredge 2500 and went to change the CMOS battery. As I changed the battery the holder flipped up and I had to reset it on the board. Consequently, I did not get the battery back in quickly enough to preserve the bios settings.

Now the computer does not find an OS at startup. Any recommendations on how to get the RAID array operative without losing the information on the systems. (I do have the entirety of the drives already backed up - but I would prefer not to have to reconfigure everything if there is an easier way.

Nothing has been done to the discs and since there was no problem with the discs originally, I am assuming there is nothing wrong with the array.
I was running Win server 2003 R2
I have a PERC 3/Di Raid controller
I have 4 HDD- 1 OS disc and 3 configured as a RAID 5 Array
The setup (F2) currently lists the discs as SCSI. If I remember right - if I just change it to RAID I will likely lose my data. (Tell me if I am wrong)

Is it possible to start the restore process up until the install asks for third party discs (i.e. the PERC utility) and then simply interrupt the install after the third party process?

What other recommendations have ye?
