The BIOS is accessed and configured through the BIOS Setup Utility.

The BIOS Setup Utility is, for all reasonable purposes, the BIOS itself.

This could brick the motherboard and render the computer unusable, making it difficult to regain functionality.

One way this is avoided is for BIOS to use what's called a "boot lock" section of its software that gets updated on its own apart from the rest so that if corruption is found, a recovery process can be undergone to prevent damage.

All available options in BIOS are configurable via the BIOS Setup Utility.

BIOS access and configuration on PC systems is independent of any operating system because the BIOS is part of the motherboard hardware.
