7.2 About the BIOS
The Basic Input/Output System (BIOS) has a setup utility stored in the BIOS flash
memory. The setup utility reports system information and you can use it to configure
the BIOS settings. The configurable data is provided with context-sensitive help and
is stored in the system's battery-backed CMOS RAM. If the configuration stored in
the CMOS RAM is invalid, the BIOS settings return to their default optimal values.
There are eight menus in the BIOS Setup Utility, which appear in this order: Main,
Advanced, PCIPnP, Boot, Security, RC settings, Chipset, and Exit. To navigate the
menus or options listed on the menu, use the keyboard arrow keys. The options or
fields that you can configure on a menu appear in color. For further instructions on
how to navigate and change settings in the BIOS Setup Utility, refer to the online
instructions provided on the menu.
The remaining sections in this chapter provide additional information about the BIOS
operations and menu options available on the server.
7.3 Default BIOS Power-On Self-Test (POST)
Events
At system startup, the BIOS performs a power-on self-test that checks the hardware
on the server to ensure that all components are present and functioning properly.
TABLE 7-1
identifies the events that can occur during BIOS POST, as well as specifies
whether these events can prevent the host from powering-on.
