Advanced Chipset Features
From this setup page you can configure
the size of the video controller’s on-chip frame buffer, set up the
controller’s DVMT (Dynamic Video Memory Technology) mode and memory size, and specify what type of display
will be used as
the system’s boot-up console output device.
DVMT is an advanced video controller function that dynamically allocates system memory to be used as video
memory in order to efficiently use of available resources to maximize graphics performance. The DVMT-related
BIOS settings configure the behavior of the DVMT function, including how much system memory is made
available for video memory purposes.
The default display setting allows selection among CRT, LCD, CRT plus LCD (default), LVDS, TV out, or CRT
plus LVDS devices. Other settings specify the resolution of devices connected to the LCD or TV output ports. The
resolutions supported in each mode are listed below.

Power Management Setup
Here, you can specify a host of options that regulate how the board’s power management features behave.
Included are options for enabling/disabling the board’s ACPI (Advanced Configuration and Power Interface)
capabilities, and specifying the degree and behavior of power management relative to the system’s mass storage
devices and display.
Additionally, this section of Setup provides several options for automatically powering up the system or resuming
from a suspended state. These include:
Power-up automatically following unexpected power loss
Resume operation based on modem or LAN connection
Resume operation based on RTC alarm
Resume operation following one of several time intervals
