The principle duties performed by the BIOS during POST (power-on-self-test) are as follows:
It verifies the integrity of the BIOS code itself.
It discovers size and verifies system memory.
It discovers, initializes, and catalogs all system hardware.
It delegates control to other BIOS if it is required.
It provides a user interface for system's configuration.
It identifies, organizes, and selects boot devices.
It executes the bootstrap program.
Answer F is incorrect. The BIOS does not interrupt the execution of all running programs.

Wait, does BIOS really verify its own code? That's wild!

I feel like E might be correct too, since verifying the BIOS code integrity seems important, but I’m not 100% certain.

I practiced a similar question, and I believe A is not part of POST duties since the user interface comes later in the boot process.

I’m not entirely sure, but I think B is also correct because it has to identify boot devices, right?

I remember that the BIOS checks the system memory during POST, so I think D is definitely one of the duties.
