have checked and corrected all of these items, contact the board vendor's
customer service representative.

instructions? Check the documentation that came with the board.
___ Are all cables installed properly?
The following items are suggestions for troubleshooting problems related to

___ If the ISA legacy board uses an interrupt, run Setup and set the interrupt
that is being used by the ISA board to Used by ISA Card.
