Hmm...the systems said to hit delete upon startup to enter setup; I did and see:
"MediaShield ROM BIOS 6.70

Detecting array ..."
The background is that my hard drive crashed, so I installed a new one. In trying to install the motherboard, the software prompted me to put a floppy into the a drive, which I couldn't do (I did buy an external floppy in order to get around this, but no luck in making it become the "a" drive.) I canceled the installation of the motherboard and have been working on this thing for days (three installations of XP and other software). At least I can access the Internet on it now.
I saw something regarding a RAID array in searching for how to fix this; I don't know what that is, but I believe that it has to do with multiple hard drives; I only have one.
Edit...
It just keeps getting better. I tried to restart the computer and now it won't boot; I even tried safe mode when prompted. I have one SATA hard drive in the system and one DVD drive, if that helps. I tried to boot with the XP CD, but when I typed "1" for the installation that I wanted to repair, nothing happened, so I pressed "Enter" and was given a "C" prompt. This is getting ridiculous; I have surely spent more than twenty four hours trying to get this computer working.
