Bios consists of a sequence of instructions from the instruction set of the machine on which it is written?

Answer 1

Yes, when the processor is turned on, it reads the contents of the BIOS into memory and starts executing it, that is, the contents of the BIOS must consist of instructions that this processor understands. Well, no one canceled the von Neumann architecture, that is, the BIOS also contains non-executable data, such as an interface description and a certain number of text messages.
It is also worth considering that the BIOS is part of the world of IBM PC compatible computers, for machines of a different architecture, the board with the hardware initialization program (and the program itself) usually have a different name and may have a slightly different structure, for example, do not provide an API to the equipment.

where you get what you smoke. I want this too!
And in the case:
1) the BIOS does not execute the process
2) BIOS and CPU are different! Blanket and padushki this different after all!
3) The processor receives machine instructions as input, decodes, executes and interacts with other computing parts of the system and gives them the result
4) The BIOS contains the program code that the processor executes.

Answer 3

Any program is a set of a sequence of processor commands.
The BIOS is not only a microprogram, but also a microcircuit that contains it.
In general, open Wikipedia and read. It's well described there.
