Hi Again, Nope, no joy. With memory that tests okay, the install goes fine and then when I reboot I get the perpetual. L 40 40 40 40 ... forever until I hit the reset switch. I have a functioning machine so I can copy programs to floppy to run on the other box. Are there any other diagnostic tools I can run for the CPU, board, PCI etc? The cdrom front it is an ATAPI. The cable goes from the Number one slot to the CD and then to the hard drive. Is this correct? It also seems the connector can go either way. What the rule on that? Is there anyway I can test the CDROM? Thanks for the help. Eric
