That sounds abslutely great - can't wait to check it out

Is there already a (complete?) documentation for the new CPU options in .bochsrc? Wait, I think I just found what I was looking for

Great work, keep those Bochs updates coming . I always liked the fact that you post updates/releases on OSDev so we may offer suggestions and/or report possible bugs and such.

When will SMP be enabled in the official releases?

When will SMP be enabled in the official releases?

It IS enabled, for official releases we have supply SMP-enabled binary.

I see Volker didn't put it in release folder (also debugger-enabled build) - will add it to release folder soon.

If you ask about when SMP is going to be enabled by default - probably never.
Just compiling SMP in already reduces emulation speed by half so I don't think it is good idea to compile releases with SMP enabled.
