Thanks, both of you, for responding so quickly. And sorry for my delay - I had a family emergency come up.
I have the hardware working now, with the RAID key and RAM installed, and BIOS and all firmware updated.
As to OS, I installed win2k03, and then diagnostic utilities, and everything went fine... but now I'm going to start over. I set my RAID 5 chunk size too small, so will wipe and recreate my container, and then I want to experiment with a couple of Linux distros. However, and here's (hopefully) my last question: Is there a way to install a SCSI DVD to this box? I notice there's an extra bay, an extra connector on the data cable (I have DAT and CD now), but no extra power connector. Can I add a Y connector to the power for the CD? Or should I replace the CD with a CD/DVD drive? Any hints on compatible models? Or any other suggestions?
I tried the Dell parts site, but they no longer list the PE2400 in their inventory for any accessories, etc.
Thanks again for any help!
