I have replaced the battery for my nvram chip and then I reprogram it. It was not easy!
Here are my resources:
I rebooted with reset-all (after a few reprogramming attempts) and I do not see the message for the invalid idprom, but I am blocked in an endless boot loop! There is no hdd, the cd-rom does not work, so somehow the Sun Blade thinks that I want a network boot. It never gives up! How can this be?
How do I stop it and enter open boot prompt? I have a PC usb keyboard attached to it, so no "stop" button.

So you have found a nice UltraSparc workstation, the Sun Blade 100 (or 150), but when starting it complains about "The IDPROM contents are invalid". The Ethernet address and Host ID have become invalid as the integrated battery of the NVRAM chip has died.
