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. >> > 15.

And thus doubt the A180 would either. 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). Scott Holbrook / rsh@fc.hp.com Unix Development Lab
