With only 4,096 pages that are 24-bit addressable, I guess we didn't want to dedicate one of them for that purpose. <SNIP> Actually, yes. It is address x'000000' and was called PSA (but is actually absolute page 0). And as I recall, it is always reserved when you have more than 1 possible CPU on a machine.
