On a lark, I tried my trusty, rusty ol' Sun 4/150 crate (4100 cpu, 32mb ram, 4xsun669 drives), and it locks up tighter than a drum when something polls the VME bus, about half way into booting. This was booting off a swap miniroot.fs. Has anyone actually gotten a 4100 cpu up, or any vme cpu on NetBSD 1.5.2? Bob
