 | What kind of power supply do I need for the Intel® Desktop Board D865GVHZ?
The Desktop Board D865GVHZ requires a power supply that complies with the ATX/ATX12V Power Supply Design Guide Version 1.2.
This design guide is available from http://www.formfactors.org
The ATX12V power supply required for the Desktop Board D865GVHZ has the standard 20-pin ATX Main Power Connector, and a 4-pin +12V Aux. Power Connector. The 4-pin +12V power connector has been added to enable the delivery of more +12VDC current to the desktop board. This connector is used by the board to power the processor's voltage regulator module (VRM).
CAUTION: The system will not boot if there is a failure to use an ATX12V power supply, or by not connecting additional power supply leads to the D865GVHZ board.

| Do I need a special power supply to support Instantly Available PC (Suspend-to-RAM)? How much +5V standby current does the power supply need to support it?
A special power supply is not needed to support “Instantly Available PC“. However, the power supply must provide enough standby current to support the needs of all wake-capable devices in the system. The more wake-capable devices in the system, the greater the standby current required from the power supply. Intel recommends starting with a power supply capable of providing a minimum of 1.5 Amps (2.0 Amps recommended) of +5V standby current. To be sure, total the amount of standby current required by the various components that can wake the system from the STR state. In your calculations, include the components on the Desktop Board D865GVHZ and on the add-in cards. Make sure the power supply provides at least that amount of standby current.

| What is the Intel® Extreme Graphics 2 controller?
Intel® Extreme Graphics 2 controller is the integrated graphics controller within the Intel® 82865GV Graphics and Memory Controller Hub (GMCH).
| |
| Can I change the size of my integrated video frame buffer?
The D865GVHZ BIOS can be set to 1 MB, 8 MB, or 16 MB video frame buffer. This memory is dedicated exclusively to the 865GV chipset video frame buffer. In addition to any memory dedicated for the video frame buffer, the 865GV chipset may dynamically allocate up to 48 MB of system memory for video, as needed, if less than 256 MB of system memory is installed. On systems with at least 256 MB of installed system memory up to 64 MB of system memory may be allocated for video.

| Does the Desktop Board D865GVHZ support Ultra ATA/100 hard drives?
Yes. The Desktop Board D865GVHZ supports Ultra ATA transfer rates up to 100 MB/sec (ATA/100) by way of the Intel® 82801EB I/O Controller Hub (ICH5) with two independent bus-mastering IDE interfaces. An Ultra ATA/100 supported hard drive and an 80 conductor IDE cable are required to take advantage of the increased bandwidth available on the IDE channel.
One of the features of the Intel Desktop Board D865GVHZ is its ability to support larger ATA/100 capable hard drives with 48-bit Logical Block Addressing (LBA) within the BIOS along with all Ultra ATA transfer rates (i.e., 33 MB/sec, 66 MB/sec and 100 MB/sec). To realize a true throughput performance difference, a hard drive may need to implement higher spindle speeds, such as 7200 RPM, and a large onboard buffer size to take advantage of the increased bandwidth available on the IDE channel.
| |
| Why is my USB 2.0 device operating at USB 1.1 speeds?
Each USB port is treated as an independent USB path, and the performance of each USB port is dependent upon the detected USB device(s) within that USB port (point-to-point) device connection. Its performance will be limited to the least capable performance element within that port's connection. For example, if you connect a USB 2.0 high-speed device to a USB 1.1 Hub, which is then connected to a USB port on the motherboard, the USB 2.0 high-speed device will be limited to the performance through that USB 1.1 Hub.
Refer to the device manufacturer of your USB device for specifications and installation requirements. Additional USB design specifications reference information can be found within the Intel Desktop Board D865GVHZ Technical Product Specification (TPS).
| |
| Does the Desktop Board D865GVHZ support additional USB 2.0 connectors?
Yes. The Desktop Board D865GVHZ has two USB headers that allow additional USB ports. Refer to the Front Panel USB Header Pin-out to ensure proper connection. Refer to the Desktop Board D865GVHZ Technical Product Specification (TPS) for more details.
| |
| Why does my Desktop Board D865GVHZ system fail to boot?
The Desktop Board D865GVHZ has specific requirements for the power sequencing and limits. A momentary switch should be used for the power on/off switch. The power supply chosen must have the additional 4-pin +12 volt connector and meet the ATX12V specification. If the power supply 2x2 connector is not plugged into the board connector located near the processor socket, the system will not boot.
| |
| How do I disable the onboard LAN?
Onboard LAN can be disabled through the desktop board BIOS Setup program. The setting is located in the Advanced screen. Refer to the D865GVHZ Technical Product Specification (TPS) for more details.
| |
| Why are the drivers on Intel's public Web site previous revisions of those available on some vendor public Web sites?
Intel performs internal testing on all drivers before posting them on the Intel developer desktop board Web site. In many cases, it is not practical to test all drivers on all desktop boards. For this reason, application vendors may release drivers that have not been tested by Intel. These drivers may be available on the vendor public site, but not on the Intel public site. This does not mean the drivers do not work; it simply indicates that Intel has not validated the drivers.
| |
| How many serial ports does the Desktop Board D865GVHZ contain?
The Desktop Board D865GVHZ has one serial port connector, located on the back panel.

| What is Intel® Active Monitor and how does it work?
Intel® Active Monitor is a system monitoring tool that alerts you when any monitored sensors on your Intel motherboard have gone outside of their recommended range. If an alert occurs, Intel Active Monitor can provide you with several different alert notifications. The standard notification is the Intel Active Monitor icon in the system tray, which turns red and flashes in the event of an alert. Additionally, you can choose to receive audio alerts and pop-up window alert messages. Intel Active Monitor is bundled on some versions of the Desktop Board D865GVHZ and is available for download. For further information about how Intel Active Monitor works, or to download the utility, please refer to: http://developer.intel.com/design/motherbd/active.htm

Memory:
|
| Does Intel qualify memory for use on Intel desktop boards?
No. OEMs and system integrators are solely responsible for qualifying the memory they include in their systems. Intel performs only limited testing of selected memory modules to verify functionality of the desktop board's design. Intel offers a program in which an independent test labs test system memory and report passing results to Intel for inclusion on our Internet based tested memory list.

Instantly Available PC and Power Supplies:
|
| What is Instantly Available PC?
Instantly Available PC, also known as Suspend-to-RAM (STR), is a technology closely associated with the S3 state of the ACPI specification. STR allows a properly configured system to go into a low-power mode, saving open applications, active files and information about the system's configuration to main memory. In this low-power state, memory remains powered to retain the system information, while most other components turn off to conserve energy. Fans are turned off to provide silent operation so the system appears “off.“ The PC can be left in STR state and awakened periodically to perform such preprogrammed events as downloading e-mail or searching and filtering Web content. An incoming phone call can also wake the PC and trigger a desired response, similar to a telephone answering machine. When an incoming request arrives via a “wake device“ or the user wishes to resume operation, the PC comes alive within a few seconds by reconfiguring itself based on the information previously saved to memory. No boot is required.
| |
| What is a wake device?
A wake device is a mechanism that awakens the system from the STR state. Typically, this mechanism is a network card or a fax/modem that is compliant with the PCI 2.2 specification. When the system goes into the STR state, these wake devices receive standby current from the power supply. Although these devices are in a low-power state they have sufficient current to remain awake to recognize incoming activity, such as a network request or a phone call.
