Re: NetBSD 5.0.2 can't handle 7455 CPU @ 1 GHz?

[Donald Lee <MacPPC2%caution.icompute.com@localhost>]

I have not yet set up to build 5.0 kernels, and was hoping not to get
(back) in that business.  I *could* put a different video card in the
machine, but I don't have any non-ATI spares.  I have one from a G3
that's much older that I could try, but that may not prove anything.

I could also put the original CPU back in the machine to see if it's
the graphics or the 7455.  I'm reluctant to do that because the
CPU swap process is touchy, and a little dust or clumsy move can
make for broken HW.

I could run the machine headless for a while as an easy experiment.
It would be easy enough to pull the graphics card, once I'm sure it will
boot.........

Thanks,
