Usb - Intel D2500CC Specification

Intel Desktop Board D2500CC Technical Product Specification
In addition, BIOS setup provides the following configuration parameters for internal
flat panel displays:
• Screen Brightness: allows the end user to set the screen brightness for the display
effective through the Power-On Self Test stage (such as while showing the splash
screen image and BIOS setup). Windows 7 will ignore this setting in favor of the
native "screen brightness" control provided by the operating system.
• Brightness Steps: allows the system integrator to configure the brightness steps for
the operating system's "screen brightness" control (such as the "Screen brightness"
adjustment slider under the Windows 7 "Power Options" control panel).
Flat Panel Configuration Changes Lock: allows the system integrator to "lock"
•
critical settings of the LVDS configuration to avoid end users potentially rendering
the display unusable.
Color Depth: allows the system integrator to select whether the panel is 24 bpp or
•
18 bpp.
Inverter Frequency and Polarity: allows the system integrator to set the operating
•
frequency and polarity of the panel inverter board.
Maximum and Minimum Inverter Current Limit (%): allows the system integrator to
•
set maximum PWM%, as appropriate, according to the power requirements of the
internal flat panel display and the selected inverter board.
Panel Power Sequencing: allows the system integrator to adjust panel sequencing
•
parameters, if necessary.
NOTE
Support for flat panel display configuration complies with the following:
1. Internal flat panel display settings are not exposed through Intel
Toolkit or Intel
2. Internal flat panel display settings will not be overwritten by loading BIOS setup
defaults.
3. Internal flat panel display settings will be preserved across BIOS updates.

NOTE
Computer systems that have an unshielded cable attached to a USB port may not meet
FCC Class B requirements, even if no device is attached to the cable. Use shielded
cable that meets the requirements for full-speed devices.
