The firmware will report only the serial ports that are actually
connected.  Thus, this box does have both of the serial ports.
On these types of boxes (B132, B132+ B160, B180), LASI always
provides the first serial port.  The second port, however, can
come from different chips depending on whether or not WAX is
present.  Some of these boxes had an EISA bus as an option.
If WAX is present, it provides the 2nd serial port.  Otherwise,
DINO provides the 2nd serial port.

This box has a WAX chip, which means that the system has an EISA slot.
EISA was an optional feature on some of these platforms.  Some B180
systems have EISA, others do not.

If the system has EISA, it has WAX and therefore has HIL support.
However, there is no HIL connector on these systems.  There is a
set of jumpers on the system board that connect the HIL signals to
2 unused pins on one of the PS/2 connectors and a special external
box that plugs into the PS/2 port and has a place to plug in the
HIL connector.  This is used by an OEM that uses the B132/B160/B180
platform but requires HIL (for some special keyboards).
