Chapter 3: Getting Started
BIOS Configuration Overview
The Performance Technologies Embedded BIOS has many separately configurable features.
These features are selected by running the built-in setup utility. The system configuration
settings are saved in a portion of the battery-backed RAM (CMOS) in the real-time clock device
and are used by the BIOS to initialize the system at boot-up or reset. The configuration is
protected by a checksum word for system integrity.
To access the setup utility, press the F2 key during the POST test and initialization at boot time.
Setup runs once the POST functions complete.
When Setup runs, an interactive configuration screen displays. See Figure 3-5, “Setup Screen
Layout” for an example. Setup parameters are divided into different categories. The available
categories are listed in a menu across the top of the setup screen. The parameters within the
highlighted (current) category are listed in the main (left) portion of the setup screen. Contextsensitive help is displayed in the right portion of the screen for each parameter. A legend of
keys is listed at the bottom of the setup screen.
Use the left and right arrow keys to select a category from the menu. Use the up and down
arrow keys to select a parameter in the main portion of the screen. Use the + or - keys or press
the Enter key to open a list of selections to change the value of a parameter.
Items in the main portion of the screen that have a triangular mark to their left are submenus.
To display a submenu, use the up and down arrow keys to highlight the submenu and then
press the Enter key.
