What did you do Howard? Checking my work to get OS 9 not the freeze on 2nd CPU access I think I gave it the wrong interrupt-parent I give it Mac-io>interrupt-controller and it should have been uni-north as that controls interrupts first. I think making this change to Openbios for the CPU properties will fix OS 9! > On Dec 19, 2025, at 9:05 AM, Howard Spoelstra <hsp.cat7(a)gmail.com> wrote: > > Hello all, > > Long time no write.
