Yes, but it still recompiles w/o going into the debugger.

It's a dual processor i486 + i860 board. One can split the installed
memory btw. the two processors. The i486 mem starts at address 0
growing upwards, and the i860 mem starts at 0xffffffff growing
downwards.

I want to map the i860 memory to be able to load i860 programs and run
them there.

I think so (what should have mapped it?). But how can I see the
mappings which exist?
