[SunHELP] Level 15 interrupt error

[Jeremy Towers]

First minimise. remove everything inc. cards, memory and disks

also reset to factory defaults with stop and i whilst powering on. Keep 
keys depressed until display shows. Also try setting diagnostic mode 
with stop and d whilst powering on.

see

http://sunsolve.sun.com/handbook_pub/Devices/System_Board/SYSBD_Station_4.html

and place one SIMM at a time starting closest to the rear.
