Hi Mark

Replacing the NVRAM is your choice, you can setup fresh each time on power on
or replace or hack the chip and add a coin cell. Personally I would just
replace as they are easily available from Key/Mouser/Farnell for not that much
money ($20?)

mangled the computer IDs wrong. If OPENSTEP uses that to identify the system
features (as Solaris 7 seems to), it may well be doing something awfully wrong
and crashing the kernel, which is triggering the Watchdog Reset.
