Windows 2000 Please help

Hello,
Ok my question is this, I have a Gateway 6400 Server and we needed to reload it due to a virus.

Now I whipped out the partition, and when I run Setup it will load, but says that is cannot find any mass storage device. I think this think has 2 hard drives it it, and I believe they are SCSI.

I attempted to Insttall windows 98, and had No Problem. How can I get Windows 2000 Server installed back? I need help getting it to detect the Hard Drive, and I know they are working because 98found and installed fine.

Please help ASAP
