Anybody have any ideas? I'd look very closely at the physical setup: particularly termination.

Drop into the Adaptec BIOS on boot using ^A and try setting the termination settings explicitly (internal and external) for both boards. -- jan grant, ILRT, University of Bristol. http://www.ilrt.bris.ac.uk/ Tel +44(0)117 9287163 Fax +44 (0)117 9287112 RFC822 jan.grant@bris.ac.uk Unfortunately, I have a very good idea how fast my keys are moving.
