The first thing the BIOS does is check the information stored in a tiny (64 bytes) amount of RAM located on a complementary metal oxide semiconductor (CMOS) chip.

I was wandering Since most of my hardware is new and I am using windows 8 pro with my Asus Z77 MB.

I remember using and old Intel MB awhile back I think it was a G33 chipset and I guess it was not compatible with some of my hardware and software So I Did my first BIOS update ever and then the PC would not boot up anymore.

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

The BIOS Setup Utility is accessed in various ways depending on your computer or motherboard make and model. BIOS contains a number of hardware configuration options that can be changed through the setup utility.

BIOS instructs the computer on how to perform a number of basic functions such as booting and keyboard control.

BIOS is also used to identify and configure the hardware in a computer such as the hard drive, floppy drive, optical drive, CPU, memory, etc.

The BIOS uses this information to modify or supplement its default programming as needed. Interrupt handlers are small pieces of software that act as translators between the hardware components and the operating system.

For example, when you press a key on your keyboard, the signal is sent to the keyboard interrupt handler, which tells the CPU what it is and passes it on to the operating system.

The BIOS software has a number of different roles, but its most important role is to load the operating system.

When you turn on your computer and the microprocessor tries to execute its first instruction, it has to get that instruction from somewhere.

To use a command, open a Command Prompt window — press Windows Key R, type cmd into the Run dialog, and press Enter.
