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).

I apologize for my ignorance, can sbdy give me a few pointers on what I need
to do to load the bootstrap on a 712/100 with no floppy?

Subject: [hppa-linux] Another bootstrap test

I would appreciate it if a few people would try out this updated bootstrap
code on their systems (same directions as last time). This is basically
complete, it loads and executes a "dummy" kernel. It has only been tested on
a C160 so far.
This is a debug version and prints a lot of noise. It would be useful if
you would capture the output and email it to me. Or at least send the
numbers 
for:
 P0_IMM_max_mem, P0_BOOTCPU_10msec, P0_COUT_class, P0_CIN_class, and
 P0_BOOTDEV_class.

If it works completely, you'll see a message from the dummy kernel image
folloed by "It is now safe to reboot." Let me know if it makes it that far
on your system.

Thanks, Jason Eckhardt.
