Is it possible to enter the bios menu without RAM?

Question

Iron

Without - in the sense that the memory strips are not installed at all.
I tried it on my old laptop - and nothing: the fan turns on, the lights turn on, the screen is black and there are no squeaks.
So it became interesting - is it implemented somehow in new computers? For example, in order to diagnose problems with this very memory.

Answer 1

To diagnose memory problems and everything else, there are POST cards.
Of course, no computer will turn on without memory.

Answer 2

will a person live without a brain in his head?) a similar question

Answer 3

Answer 4

No, you can't, you can only enjoy the squeak of the beeper.
