<title>RE: [rescue] Help me rescue my Sun Ultra 10 (2x)</title>
<p style="padding: 0; margin: 0; "><span style="font-size: 11pt; font-family: arial, helvetica, sans-serif;">Yeah, I purchased some noew NVRAMs I hope they come pretty quickly as I was planning to do a sort of mini-documentary on the SunPCi. I have been reverse engineering the Solaris Kernel interface as well as the actual hardware interface. The idea is to ultimately have Linux drivers for the SunPCi cards, and a less terrible client application for Solaris. I got most things working, but now my development systems are dead. :-/</span></p>

<p style="padding: 0; margin: 0; "><span style="font-size: 11pt; font-family: arial, helvetica, sans-serif;">I couldn't find the p/n on either boards. Where would I find those? Are they actually printed on the boards somewhere? </span></p>

<pre style="white-space: pre-wrap; word-wrap: break-word;">Hi<br><br>Well the obvious thing is to try a new NVRAM, (use a 48T58) to see if that cures it.<br><br>If not then the motherboards were never that reliable and suspect them next. Out of interest what are the motherboard p/n?
