[SunHELP] Help required on OK prompt programming

[Blake Matheny]

First off your nvram is dead, you should replace it. You can in the mean
time however, reprogram the nvram. To do that enter the following commands
at the ok prompt:
1 0 mkp
real-machine-type 1 mkp
8 2 mkp
0 3 mkp
20 4 mkp
c0 5 mkp
ff 6 mkp
ee 7 mkp
0 8 mkp
0 9 mkp
0 a mkp
0 b mkp
c0 c mkp
ff d mkp
ee e mkp
0 f 0 do i idprom@ xor loop f mkp

Hi all

I am facing this problem of the ethernet address and hostid getting set to
ffffffff .And when I try to boot the machine it says IDPROM contents are
invalid.The machine is a SS10 machine with solaris 2.6 loaded on it.This has
also happened on an Ultra-2 machine.If I am not wrong the prom contents are
invalid and we need to reprogram the NVRAM.I know that this could be done
with the mkp command at the OK prompt(Had read somewhere) but I am not sure
of the exact commands.The first time we faced this problem we had to replace
the NVRAM which was very costly.Repeated failure of this is costing me a
lot.

Any help on this is appreciated.


Thanks
