Restoring a PC Server 500 P/390

I thought I had captioned that picture. It's the original RAID controller
which I am not using. If I plug it in it starts the disks in the RAID array
which takes ages, and steals the hard disk BIOS vector which I need for the
SCSI card that's running the system.
I didn't want to remove it fully as I need to label the cables feeding it.
One feeds the top drive bays, and the other the bottom so if I ever need to
put it back it I need to know which is which.
If I get some free time I will have a go at starting the disks in it and
repairing the RAID array, and perhaps copy the disks that are installed.

I gotta ask, what's the deal with the dangling card? That cracked me up!
Thanks for posting some pics!

Well I found an XGA2 card in the pile of bits so now I have 1024x768 display
resolution. I have swapped the CDROM for a SCSI DVD drive.
I managed to boot MTS and there are a few pics here:-

next job is to tidy up and re-assemble the case..
