Chapter 4 BIOS
BIOS are a program located on a Flash memory chip on a circuit board. It is used to
initialize and set up the I/O peripherals and interface cards of the system, which
includes time, date, hard disk drive, the ISA bus and connected devices such as the
video display, diskette drive, and the keyboard. This program will not be lost when
you turn off the system.
The BIOS provides a menu-driven interface to the console subsystem. The console
subsystem contains special software, called firmware that interacts directly with the
hardware components and facilitates interaction between the system hardware and
the operating system.
The BIOS default values ensure that the system will function at its normal capability.
In the worst situation the user may have corrupted the original settings set by the
manufacturer.
All the changes you make will be saved in the system RAM and will not be lost after
power-off.
