- Just out of curiosity, where is "sysinfo" physically located
- in an Indigo? The reason I ask is that I kind of expected
- a copy protection scheme that uses "sysinfo" to break when
- I swapped out my R3K cpu board with a R4K cpu board (and
- power supplies). Suprisingly it didn't seem to affect the
- copy protection scheme :)
-
- So :
-
- (1) the Vendor's copy protection scheme doesn't work
- (2) SGI loaded the "sysinfo" on the replacement cpu
- with the same 'unique identifier' as the R3K card
- (can two cards have the same *unique* identifier? :)
- (3) The physical location of the "sysinfo" is NOT on the
- cpu card, or the graphics card, or powersupply.
- That only leaves the backplane....
-
- Of course is the location of "sysinfo" is a secret then forget
- I even brought this up :)
