Chapter 3 System BIOS

BIOS OPERATION Sections 3 through 8 of this manual describe the operation of the American Megatrends AMIBIOS and the AMIBIOS Setup Utility. Refer to Running AMIBIOS Setup later in this chapter for standard Setup screens, options and defaults. The available Setup screens, options and defaults may vary if you have a custom BIOS.

When the system is powered on, AMIBIOS performs the Power-On Self Test (POST) routines. These routines are divided into two phases:

1)System Test and Initialization. Test and initialize system boards for normal operations.

2)System Configuration Verification. Compare defined configuration with hardware actually installed.

If an error is encountered during the diagnostic tests, the error is reported in one of two different ways. If the error occurs before the display device is initialized, a series of beeps is transmitted. If the error occurs after the display device is initialized, the error message is displayed on the screen. See BIOS Errors later in this section for more infor- mation on error handling.

The following are some of the Power-On Self Tests (POSTs) which are performed when the system is powered on:

CMOS Checksum Calculation

Keyboard Controller Test

CMOS Shutdown Register Test

8254 Timer Test

Memory Refresh Test

Display Memory Read/Write Test

Display Type Verification

Entering Protected Mode

Memory Size Calculation

Conventional and Extended Memory Test

DMA Controller Tests

Keyboard Test

System Configuration Verification and Setup

NOTE: When you perform a warm boot by pressing <Ctrl> + <Alt> + <Del>, all memory tests are bypassed.

AMIBIOS checks system and cache memory and reports them on both the initial AMIBIOS screen and the AMIBIOS System Configuration screen which appears after POST is completed. AMIBIOS attempts to initialize the peripheral devices by verifying
