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® Integrator Toolkit or Intel® Integrator Assistant GUIs. 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. 1.5.2 USB The board provides up to seven USB 2.0 ports, supports UHCI and EHCI, and uses UHCI- and EHCI-compatible drivers: • Four back panel ports • Two ports are implemented with a dual port internal header for front panel cabling • One port is implemented with an internal header (brown-colored) that supports an Intel® Z-U130 USB Solid-State Drive or compatible device 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. 22

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
®
Integrator
Toolkit or Intel
®
Integrator Assistant GUIs.
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.
1.5.2
USB
The board provides up to seven USB 2.0 ports, supports UHCI and EHCI, and uses
UHCI- and EHCI-compatible drivers:
•
Four back panel ports
•
Two ports are implemented with a dual port internal header for front panel cabling
•
One port is implemented with an internal header (brown-colored) that supports an
Intel
®
Z-U130 USB Solid-State Drive or compatible device
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.
