Intel

EP80579 Software Drivers for Embedded Applications on FreeBSD*

GSG September 2009

30 Order Number: 320152-005US

6.1.1 Serial Console Redirection

The pre-boot firmware supports redirection of both video and keyboard via a serial

port. When console redirection is enabled, the remote console terminal sends

keystrokes to the Intel

EP80579 Development Board pre-boot firmware and the pre-

boot firmware redirects the video to the console terminal.

As an option, the Intel

EP80579 Development Board can be operated without

keyboard or video and can run entirely via the remote serial console. This includes

accessing the pre-boot firmware setup menu.

Console redirection ends when operating system boot up begins. After boot up begins,

the operating system is responsible for continuing the redirection.

Note: pre-boot firmware console redirection is text only. Graphical data, such as logos, are

not redirected.

Table 4 shows the default settings of the serial console redirection.

6.1.2 Changing the Boot Device

Use the following procedure to change the boot device:

1. Press the <Del> key during POST to enter the pre-boot firmware setup menu.

2. Use the arrow keys to navigate to the <BOOT> menu.

3. Move the cursor to <Boot Device Priority>.

4. Select the desired booting sequence list.

Note: Follow the instructions on the right side of the pre-boot firmware screen to navigate

and change pre-boot firmware settings.

6.1.3 Maximum Memory Speed Setup

The maximum memory speed supported on the development board can be selected

using the Maximum Memory Speed Setup option available in the BIOS Setup Menu on

the Chipset tab.

Enter the BIOS Setup Menu and select the Chipset tab. Select North bridge, and

navigate down to the bottom option, titled Max Memory Speed Support. Select this

option using the Enter button. A selection box appears providing the following options:

•400 MHz
