More than what will fit here. As to the modern CMOS that's a confusing term when we have to cover dozens of PC designs from the early 8088 to today's EFI model.
All this is on the web but I can't condense it here. Can you slim down your question or tell why this came up?
Hello, everyone. As I understand, the very first instructions CPU performs are startup instructions sent by BIOS, but I don't understand, where those instructions are stored. Also there are a lot of other things like: data for Power-on Self Test, data for activating other BIOS chips on different cards (for example: SCSI) etc. I used to think that all this data's stored in CMOS, but recently I read an article that said that modern CMOS is only responsible for time and date.
I really appreciate your help!
