SparcClassic /Classic X Terminal NVRAM differences
This section was supplied by Gary Cook. I have not been
able to try this personally because I don't currently have access to this
type of machine.
Change the following locations in NVRAM to switch between Classic and
Classic
Address ClassicX Value Classic Value
71202004 ff 00
71202005 12 00
71202006 08 00
71202007 36 00
Notes:
* Classic X requires all locations to be set to above values. If they are
not, the system takes on the Classic personality.
* Bootprom for Classic X cannot be Version 2.9. This version will ignore
the above NVRAM changes. Classic X requires earlier versions, such as
2.12.
