PCI-QUAD04

Has anyone done any work with the Measurement Computing PCI-QUAD04
board? I'm doing a very simple driver (not comedi based at this
point) and seeing some very troublesome problems.

After doing the general PCI setup so I have access to the I/O ports
on the board, I find that reading the data registers on the LS7266
decoder chips ALWAYS returns 0's. Reading the status register gives
reasonable values.  Values can be written and read properly to two
other ports in the I/O space with out problems. 

Has anyone seen a problem like this before?
