Ultra 1 Fails to Boot

I just got an Ultra 1 a couple of days ago, and when I booted it up, it said that its IDPROM was invalid and I was getting TOD errors. I turned off the station and now it won't boot. On my keyboard, it'll light up the caps lock and num lock, then lights up compose and scroll lock about a second after, then it sits there and does nothing. I looked up the POST code, and from what I've read, it's saying that the cpu board has failed, and that it has no memory. Could replacing the IDPROM solve the issue I'm having?

    Hello,

    Maybe. I would recommend that you dettach the keyboard and attach to the serial console port.
    Review the trouble-shooting chapter in the Ultra 1 Service Manual.

    You can re-program the IDPROM ([*SUN NVRAM/hostid FAQ*|http://www.squirrel.com/sun-nvram-hostid.faq.html]). If the battery in the IDPROM (NVRAM/Timekeeper) is empty, it loses the content with the next power-cycling. The contents only "survives" a warm-start.

    If the fault is caused by the empty battery, either get a replacement NVRAM or use the instructions [*NVRAM Battery Fix FAQ*|http://www.bhargavaz.net/nvram/].

    I've gone through the service manuals for my Ultra 1E and for the regular Ultra 1, but couldn't find anything about using a serial connection for troubleshooting my problem.

    Hello,

    the service manuals for the Ultra 1/1E lack indeed the usual "Setting Up a Tip Connection" chapter.

    Get the [*Sun Ultra 2 Series Service Manual*|http://docs.sun.com/source/802-2561-11/802-2561-11.pdf] instead and review chapter 3.2.1.

    Can you confirm that you used a known-good null-modem cable and set the communication parameters properly ?

    Have you opened the system, removed the dust, reseated the memory modules and checked the cables ?
