**82378       System I/O (SIO) (82378IB and 82378ZB)           c:Mar93
***Notes:...
***Info:...
***Versions:
82378IB   c:mar93  (Only supports 2 PCI Bus Masters)
82378ZB   c:dec93  (Supports 4 PCI Bus Masters)
82378ZB   c:dec94  (Supports 6 PCI Bus Masters)

Don't know how to tell the difference between the last 2.

For some more (important) details see the Configurations section of
the 82430LX section, and the errata document below:
