S2DL3 problems, any ideas?

[Mr. Joe Blow]

I haven't seen any info in this group on the S2DL3 yet, I hope I'm not
the test dummy.

Setup:

Xeon 733 x2
IBM or Crucial 256 MB ECC Registered dimm
In-Win R2000 case with back plain
3 WD 18 gig Ultra 160 10k 80 pin drives
Dual port Adaptec ultra 160 raid card 3200s
S3 Virge PCI card
Creative 48x IDE Infra CD-Rom
Mitsumi floppy

Problem:

Upon booting off of the Adaptec CD I get this message while extracting
Linux: CRC Error

If I boot off of a 98 floppy disk, run fdisk, setup a partition,
reboot, run format, lock, and the NT4 setup, the machine may or may
not copy the files from the CD 0 to 100 percent. If it does begin
copying the files it will finish. Upon reboot, after initializing,
once it hits the hard drive, I get a Dos screen with address errors
and receive a message that the system has been halted. Pressing
cntrl/alt/del resets the machine at that point.

I swapped the memory, same problem
Tried a different memory slot, same problem
I swapped the video card 5 times, Matrox PCI, S3 Virge PCI,
Cybervision PCI, Stealth ISA, same problem
I plugged in only one scsi2 narrow drive to the scsi 2 narrow on board
port, no other scsi cards, same problem
I removed both CPUs one at a time and used the dummy plug, dummy plug
always in slot 2, same problem
I dropped the clock speed the 633, same problem
Cleared the Bios, same problem
Flashed it, same problem
Disabled all the on board periphs in the bios, same problem
Removed the floppy and CD-Rom, same problem

You name it, and I hope I've tried it

Any ideas? I'm tired!
Supermicro is not any help.........
Thanks,

Joe
