NVRAM resuscitation (Was Re: SPARCstation 20 with SCSI2SD)

[Gordon Henderson]

As an aside - once upon a time I worked for a company that made their own 
Sparc boards to fit inside a supercomputer and several of them were inside 
secure military/government establishments. Sometimes a board would fail 
and have to go back for a fix - and then the RTC/NVRAM chip had to be 
removed because - you know, those 64 bytes of battery backed RAM might 
just hold some state secret or something...

Fun days.
