Mentions 2.14.3 .. might that be what you have? I'm not sure if the PROM
banner is showing the entire version number, or truncating it. The MBus
FAQ says I need 2.10.3 to run SM51s, and here I am running, if my PROM
banner were to be believed, 2.10, without issues with that module.

It appears from that chart that the only higher release from 2.14 is
2.14(H), which enables some of the 180MHz HyperSPARC modules. Since I
don't plan on spending that kind of cash on MBus modules anytime soon, it
doesn't matter to me.

I wonder though -- how backwards-compatible are these PROM revisions? I
would hope that I wouldn't lose the ability to run SuperSPARC CPUs (eg
SM51) with this later version. I assume that they DTRT and made it
backwards-compatible, but ... don't know if I should be making that
assumption.
