2597.1This should have been in .0BERGEN::ARNEMThe Pan Galactic Gargle Blaster sounds nice, or what ?Wed May 14 1997 15:2217
I've been reading about this pass-x of the ev4 and ev5 chip.

What exactly is this pass, is it a rev of the chip itself?

And how do i find out the pass-x on a module/chip.

Ive got a 2100 with 2 BA2040-BA rev b01
on the chip itself it's printed: 
21-40658-17   rev: K    Datacode: 9614    lot: b-52109-31
21-40658-17   rev: K    Datacode: 9628    lot: b-52582-44


Does this tell anyone what pass numer i've got on these
chips?

Regards
Arne J Moe

    over time the chip evolves and minor features are added.
    
    Usually these are 100% transparent to ordinary users, but are very
    important to hardware groups - for example, later passes of ev56 can
    support slightly faster cache bandwidth in certain circumstances than
    can earlier passes.
    
    The differences among the passes tend to be poorly documented outside
    of the groups with an immediate need to know this level of detail.
2597.3Yes, but?BERGEN::ARNEMThe Pan Galactic Gargle Blaster sounds nice, or what ?Tue May 20 1997 10:217
    Thanx for the answer,
    
    but still. How do I find what pass i've got in my 2 cpu's.
