Pre-boot (BIOS) Firmware—EP80579 Integrated Processor

6.0 Pre-boot (BIOS) Firmware

The pre-boot firmware is executed when the system is powered up or reset. It

initializes and configures system memory, devices and buses/interfaces.

The pre-boot firmware is based on the AMI Aptio* 4.5 core and compliant to EFI v1.1.

The firmware is stored in the Firmware Hub (FWH) or SPI (Serial Peripheral Interface)

Flash; the FWH or SPI Flash can be updated using a flash utility tool that is provided by

Intel or by using a floppy drive connected to the floppy header.

The pre-boot firmware setup menu can be used to view and modify the system settings

for the development board. The setup menu is accessed by pressing the <Del> key

during pre-boot firmware boot up (before the operating system boot begins). The setup

menu bar is shown in Table 2.
