That's pretty much where I'm at - my understanding of most of this hasn't moved since CP/M. CPU boots, PC sets to zero, starts reading instructions from ROM, optionally paging out the ROM if we really need to recover that memory window. I get that x86 is a bit messier because you have optional bioses that get run, and then you read and run the first page of the storage device, but .. man have they made life difficult since I last paid attention. |
