I bought a R300, and I had it going to the boot menu trying to play around with boot order, etc. I left it there for a week, and when I got back to working on the machine, I rebooted it. Afterward, the machine no longer probes/detects the on board, built-in SATA RAID controller (Perc6i I think) anymore. I definitely can see the controller before, but now I don't see it, and the system complains there is no boot device. The drive light is on.

Has anyone ran into this problem before?

If it doesn't show up during the POST, I would try reseating the controller and drive connections (if applicable).

If that doesn't work, someone or something probably let the magic smoke out of it. Call Dell as a warrantee call.

Without having one handy to look at, try this: When the machine boots up access the BIOS settings and look for a setting to change the controller from SCSI to RAID mode. If it's not in the BIOS settings it will be in the controller settings (CTRL-M?).
