Interrupt 2 on the card is interrupt 9 in the operating system, so you 
want to sysadm with 9 and then set the WD interrupt jumper at the left-hand
end (interrupt 2).  The WD driver in Streamlined TCP figures out if this
is the problem and prints out a message on the console, I don't know if the
386/ix driver does.

The motherboard mhz is not the problem, the Dell machine should clock the bus
somewhere between 6-10mhz and the WD should work fine.  I think the WD cards 
come with a disk that has a diagnostic on it; did you run that?

The device driver for the WD board should do a complete check on the card
when the system comes up (the one in Streamlined TCP does).  You can test
the digital and analog signal path at various points and make sure the 
shared memory works.

The WD driver in 386/ix was written by Western Digital, and is available in
source form from them, if all else fails.
