Hi

Suggest you install a graphics card and Sun keyboard and set switch to normal
bootup. If it comes up ok, then check the printenv list at ok prompt, do a
set-defaults  and see if the serial output without keyboard attached works
now.

Alternative is to attach Sun keyboard and hold stop and N key down on poweron
which on most early systems will reset NVRAM to defaults.
