[comp.sys.intel] 80286 / 80386 LOADALL instruction

I've heard a rumor that the 80286 and 80386 have an undocumented
'LOADALL' instruction which can be used to access extended memory.
I'm interested in any info on this subject.

I've also heard that the chip reset is not the only way to xfer
between real and protected modes. Ditto on th info.

Thanks
