BIOS 3.1 BIOS Introduction The Award BIOS (Basic Input/Output System) installed in your computer system’s. The BIOS provides for a standard device such as disk drives, serial ports and parallel ports. It also adds password protection as well as special support for detailed fine-tuning of the chipset controlling the entire system.
BIOS 3.3 Standard CMOS Features “Standard CMOS Features” allows you to record some basic hardware configurations in your computer system and set the system clock and error handling. card already installed working system, will need select this option. You will need to run the Standard CMOS option, however, if you change your system hardware configurations, such as onboard battery fails, or the configuration stored in the CMOS memory was lost or damaged.

BIOS Halt On This field determines whether or not the system will halt if an error is detected during power up. All errors (default) Whenever the BIOS detects a non-fatal error, the system will stop and you will be prompted. No errors The system boot will not be halted for any error that may be detected.
BIOS 3.4 Advanced BIOS Features Quick Power On Self Test When enabled, this field speeds up the Power On Self Test (POST) after the system is turned on. If it is set to Enabled, BIOS will skip some items. Setting: Enabled (Default), Disabled. First/ Second Boot Device These fields determine the drive that the system searches first for an operating system.

BIOS IDE Primary Master/Slave PIO It allows your system HDD controller to run faster. Rather than having the BIOS issue with a series of commands that transferring to or from the disk drive, PIO (Programmed Input/Output) allows the BIOS to communicate with the controller and CPU directly. When Auto is selected, the BIOS will select the best available mode.
