Resolving the" NVRAM contents are invalid message" while booting SUN ultra 10 machines

 

Resolving the” NVRAM contents are invalid message” while booting SUN ultra 10 machines ,do the following:

 

Let’s assume the Ethernet address is 8:0:20:af:b1:cc and the hostid is 80afb1cc , then do the following

 

In ok promt

 

Ok 0 0 mkp

Ok 8 0 20 af b1 cc 80afb1cc mkpl

^d^r(control+d followed by control+r)

Ok boot

 

If still have troubles, try 1 1 mkp instead of 0 0 mkp

 

Good Luck
