Configuring the Video BIOS and EFI

The final page of the Intel® EMGD Configuration allows you to configure your video BIOS (if you are creating a configuration that includes the Video BIOS) and EFI. You can configure the Video BIOS by clicking Next after you configure each port. When you do, the following Video BIOS and EFI Configuration Page appears.

Video BIOS Configuration Page

 

From this page, you can customize POST (Power On Self Test) messages and default display modes as well as matching port devices to System BIOS ports.

The table below describes each field on this page.

Video BIOS Settings

Description

Primary Display Mode

This section allows you to specify a standard or a customized display mode for the primary display. You can select a standard mode from any of the standard modes listed in the drop-down list. If you want to use a customized mode for the primary display, check the Custom check box and enter the mode number in the box. For a complete list of customized VGA and VESA modes, refer to Table 24. Supported VGA Video Display Modes and Table 25. VESA Modes Supported by Video BIOS.

Secondary Display Mode

This section allows you to specify a standard or a customized display mode for the secondary display. You can select a standard mode from any of the standard modes listed in the drop-down list. If you want to use a customized mode for the secondary display, check the Custom check box and enter the mode number in the box. For a complete list of customized VGA and VESA modes, refer to Table 24. Supported VGA Video Display Modes and Table 25. VESA Modes Supported by Video BIOS.

5F Functions

These settings allow you to enable or disable the five System BIOS 15h interrupt hooks. (Please see Intel® 5F Extended Interface Functions for more information on 5F functions.)

All five functions are enabled by default.

Common to Port

The Common to Port section lets you match port devices with common System BIOS ports. This allows the Video BIOS to retrieve information about the port from the System BIOS. It allows you to associate standard display names used in most system BIOSs to specific ports that are recognized by Intel® EMGD (for example, LVDS, sDVO). The VBIOS makes this association when the VBIOS calls the System BIOS Intel® 5F interrupt functions.

 

This setting consists of six numbers, where each number is associated with one of the System BIOS displays:

 

1 : CRT - Standard analog CRT

2 : TV1 - TV Output 1

3 : EFP1 - DVI Flat Panel 1

4 : LFP - Local Flat Panel (Internal LVDS display)

5 : TV2 - TV Output 2

6 : EFP2 - DVI Flat Panel 2

 

The values above are an example of the typical displays and corresponding order used by a system BIOS. However, this may vary depending on how your system BIOS has implemented the displays and the Intel 5F interrupt functions.

 

The value in each position in the setting should be the associated port device. Using the typical settings above, if you want to associate CRT in the system BIOS with the internal CRT (port 1) and LFP in the system BIOS with internal LVDS (port 4) in the VBIOS, select CRT from the VBIOS Port Devices list and click the left arrow button next to the CRT row in the Matches column, and then select LFP from the VBIOS Port Devices list and click the left arrow button next to the LFP row in the Matches column.

 

Notes: This feature must be compatible with the System BIOS. If the System BIOS does not properly implement the Intel 5F functions, then using the Common to Port feature could cause unpredictable results with the displays. If you are unsure, leave the Matches column blank for all ports to disable this feature.

The Display Detect field on the Chipset Configuration page must be set to Enable in order for the Common to Port values to be used.

Enable POST messages to display

To enable Power On Self Test (POST) messages to display during the power on sequence, check this box. If left unchecked (i.e., cleared), the POST messages do not display.

OEM String

Enter a string of up to 100 characters. This string appears on the display when the Video BIOS starts up. The default is a blank string.

OEM Vendor Name

Enter a string of up to 80 characters that identifies the OEM Vendor. This string appears on the display when the Video BIOS starts up. The default is a blank string.

OEM Product Name

Enter a string of up to 80 characters that identifies the OEM Product Revision. This string appears on the display when the Video BIOS starts up. The default is a blank string.

OEM Product Revision

Enter a string of up to 80 characters that identifies the OEM Product Revision. This string appears on the display when the Video BIOS starts up. The default is a blank string.

Number of Seconds to Display

Enter the number of seconds to display the above information. The default is 1.
