You mean the login prompt?

Get a null modem cable, hook up the 'broken' machine's com1 port to a
non-broken machine that can run a terminal program on a serial port.
Use USERCONFIG to set the flags on SIO0 to "0x10" or perhaps "0x30",
and record what comes out of the broken machines serial port (at 9600baud)
when you do a boot -v.
