You need to set diag-switch? to true and diag-level to max in OBP, then power off, wait 1-2 minutes, and power on again. Then watch the serial port. Normally, HPOST will list the memory modules it sees, and report on any errors. The DIMM sockets are marked Uxxxx on the motherboard, and HPOST will use these names. Also, have a look at the "Sun Ultra 60 Service Manual" at download.oracle.com/docs/cd/E19127-01/ultra60.ws/.../805-1709-12.pdf Regards - Volker -- ------------------------------------------------------------------------ Volker A.
