PhoenixBIOS features and setup
Issue G 77
Field Explanation
IGD – Device 2,
Function 1
Choose whether to enable or disable IGD - Device 2,
Function 1. This is the second graphics controller on the
855GME chipset. This chipset has two graphics controllers
integrated within one device, thus enabling two independent
displays showing different images. You can turn off the second
graphics controller here, for example if you want to support
other video cards.
IGD – Memory Size
Choose how much Main Memory the Internal Graphics Device
is to use. You can choose 1, 8, 16 or 32MB.
IGD – Boot Type
Choose the video device to be activated during the POST
routine. The options you can choose from are listed in the Item
Specific Help panel.
IGD – LCD Panel Type
Choose the LCD panel to be used by the Internal Graphics
Device.
IGD – Panel Scaling
Choose the LCD panel scaling option to be used by the
Internal Graphics Device. You can choose:
•
Auto to use the Intel video BIOS setting.
•
Force Scaling to scale a lower resolution image so that
it fits a higher resolution display.
•
Off to use the designated resolution. This may result in a
border around the image when it is displayed on screen.
For these settings to work correctly, the attached
display must support EDID (Extended Display
Identification Data). This gives the video BIOS an
indication of the native resolution of the display.
IGD – TV Standard
Choose the TV signal transmission standard used by the
Internal Graphics Device. The options available are listed in
the Item Specific Help panel on the right-hand side.
IGD - Portrait Mode
Specify whether portrait mode in the Internal Graphics Device
is Enabled or Disabled.
Alternatively select Auto, in which case the setting is based on
setup tables in the BIOS and on the EDID readback from the
display.
SSC Chip Spread
Spectrum
Choose whether to use the spread spectrum feature of the
Spread Spectrum Clock chip, by selecting either Enabled or
Disabled.
SSC value
Choose the % spread to be used.
