BIOS CONFIGURATION
The system BIOS is based on the Phoenix
extensions. BIOS features include:
• ACPI 2.0 wake up from S3, S4, and S5
• High-resolution, GUI-based, customizable splash screen
• COM port console redirection
• Pre-boot Execution Environment (PXE) boot
• CMOS saving and restoration of nonvolatile CMOS parameters via BIOS setup utility
Using the BIOS setup utility, you can display and modify the system configuration via an
attached monitor and keyboard. The BIOS configuration information is stored in the
nonvolatile CMOS RAM, and the BIOS uses it to initialize the system.
The system BIOS performs a Power On Self Test (POST) upon power on or reset, which
attempts to determine whether further operation is possible:
• If a warning occurs, a message is displayed on the primary display device but the boot
process does not stop.
• If an error is detected, the boot process is halted.
Failures during POST can be indicated by POST checkpoint codes on the BIOS setup screen
or POST card that is installed on the carrier board I/O connector. For detailed information,
see POST checkpoint codes on page
After POST completes, the system BIOS will search for boot devices in the order
configured by the BIOS setup utility and load an operating system from the first boot
device found. Control is then passed to the operating system and the system BIOS plays no
further part in the boot process except to provide run-time services.
To enter the BIOS setup utility, press F2 during POST. The system BIOS setup screens and
menu options are the standard Phoenix TrustedCore BIOS screens including CE915GM
extensions. Use the up, down, left, and right arrow keys on your keyboard to navigate to
appropriate menu options. Online help is provided in the BIOS setup to explain options.
After you have completed the BIOS settings, press F10 or use the commands on the Exit
menu to save changes. Press Esc to go immediately to the Exit menu.
