Yes, but usually that process does only reset the boot flags described in in the maunal, it does not reset the hardware relevant stuff like the hostID and MAC (those are lost in the Sparc Stations when the NVRAM is pulled or completely empty). But of course one can not be entirely sure - I ordered a "new" NVRAM for the UltraBookII just in case it did not like getting pulled and the battery attached.
Upon reading the NVRAM withoug pullig it and using a hardware reader device: I guess that with the peek commands (see OpenFirmware guide, https://docs.oracle.com/cd/E19457-01/801-7042/801-7042.pdf) one can read the NVRAM contents. Of course no idea how to find the memory address where it is located. The adress space is huge compared to the 8k of the NVRAM...
