[QUOTE="tiredretired, post: 1691392, member: 313325"] That is what I get when I attempt to access the Apple Hardware Test by holding down Option/D during boot. This came about because I was getting the dreaded periodic 3 klaxons and reboot. I recently upgraded my system RAM from 4GB to 8GB along with changing out the internal HDD. OWC advised me to reset the PRAM, which I have done. Does anyone know what that code means? The computer is running great and OWC says that it is important to do a PRAM reset whenever RAM is changed or upgraded. Makes sense to me, but the error code is bugging me. Does not allow me to progress to the Hardware Test. As always, thanx in advance for any advice from the experts. Cheers and MERRY CHRISTMAS to all. [/QUOTE]
