Am I right in believing that due to the proliferation of single-processor motherboards with APICs that it's generally advisable for x86 machines to have either *norealmode= or *nomp= in PLAN9.INI?
No. The E820 scanner uses realmode and works fine even on multiprocessors.
Should the realmode code reject attempts to use it if the kernel has already gone down the APIC path? Are there other things (APM?) which should disable themselves?
Why would it be incompatible with APICs? When we go to real mode we turn off interrupts on the local processor. Russ
