In 2.11BSD the whole kernel is ALWAYS resident, no swapping here. It is
just not all mapped at any given time. The overlay system is pretty much
transparent to the kernel.
No, that was the first thing I looked for.
Actually, a couple of the
overlays were too large, so I moved drivers _into_ the resident kernel.
Good idea from a performance standpoint, but not for the kernel to function
and again all the overlays, BASE, OV1, OV2, etc. are always in memory, just
not always mapped into the processor instruction space by a page register.

Glad you got it working!
