[SunRescue] IDPROM problem with OPUStation PM 5000

[Carsten Bartels]

A few days ago i received a old OPUStation Personal Mainframe 5000. A
few seconds after switch it on an error message appears on the screen
an the System halts:

 ------------------------------------------------------------------
|        OPUStation Personal Mainframe 5000, Type-4 Keyboard       |
|        ROM Rev. 1.0, 8MB Memory installed, Serial #16777215      |
|        Ethernet address ff:ff:ff:ff:ff:ff, Host ID: 20ffffff.    |
|                                                                  |
|The IDPROM checksum is incorrect.                                 |
|#                                                                 |
|                                                                  |
 ------------------------------------------------------------------

In my opinion the battery from the RTC/NVRAM is empty --> bad
Serial, Ethernet and Host values.
Was the IDPROM-checksum also stored in the RTC/NVRAM?

What can I do to get the machine run? Do I have to reprogramm a new
RTC/NVRAM with the (unknown) original values?
