Hello I have a fast data access MMU miss since this morning when I am trying to boot with the cdrom of my U60. Searching the net , it seems the motherboard is defective, Is someone can confirm me the this state of fact ?
This is most often caused by a faulty CDROM or drive.The OBP has minimal intelligence, so it reads the initial boot sector and executes it without checking for corruption. This inevitably leads to an illegal memory reference and thus to the message that you see.
Try using a known good Sun pressed CD, not a CDR.If this fails your drive has probably expired, if you do not have a spare try booting from the network. The older drives in the U60 will probably have problems reading CDRs written at high speed and will almost certainly not read a CDRW.
