This is the keyboard connector.  Some older C-class workstations have both
HIL and PS/2; forget it exists.

IPL, parts of the kernel and the boot interface all use the console device
selected in nvram.  my guess is this is graphics (since you don't see
anything on your serial port when booting the machine ?), so you should
either connect a monitor or try to remove all keyboards.

You should make sure you have a working firmware console first (IPL does
not really care whether it's connected to serial or graphics).

That comment is in ipl_c.c only because the command line was changed and
it was set there back then.
