Hardware

I have two ultra 10 workstations, one worked for a few days and then just stoped POSTing. I pulled all of the hardware and nothing happened differently. I looked up the Sun service manual. Had two LED's on my keyboard on: Caps Lock and Scroll Lock. According to the Sun Ultra 10 Manual (http://www.sun.com/products-n-solutions/hardware/docs/pdf/805-7764-12.pdf) those LED's mean bad memory. I checked my memory in a known good machine, and the memory turns out to be good. I swapped my CPU into the known good machine and it also is good. I had nothing else to try so I pulled the NVRAM from the bad machine and stuck it in the known good machine. The problem replcated and I had the same results in the formerly known good machine; however, other than the LED's flashing when the system is powered on I got no POST error codes. I then put the previously known good machine's NVRAM back in it and I still have the same problem. I've tried Stop+N with no luck! Thanks in advance for the help.
