Refer to Section 2.1.1 on page 34 for information on the total amount of addressable memory. Minimum total system memory: 128 MB Non-ECC DIMMs Serial Presence Detect DDR2 667 MHz or DDR2 533 MHz SDRAM DIMMs
The board has two DIMM sockets and supports the following memory features:
NOTE
To be fully compliant with all applicable DDR SDRAM memory specifications, the board should be populated with DIMMs that support the Serial Presence Detect (SPD) data structure. This allows the BIOS to read the SPD data and program the chipset to accurately configure memory settings for optimum performance. If non-SPD memory is installed, the BIOS will attempt to correctly configure the memory settings, but performance and reliability may be impacted or the DIMMs may not function under the determined frequency. Table 3 lists the supported DIMM configurations. Table 3. Supported Memory Configurations

Memory Configurations
Dual channel (Interleaved) mode. This mode offers the highest throughput for real world applications. Dual channel mode is enabled when the installed memory capacities of both DIMM channels are equal. Technology and device width can vary from one channel to the other but the installed memory capacity for each channel must be equal. If different speed DIMMs are used between channels, the slowest memory timing will be used. Single channel (Asymmetric) mode. This mode is equivalent to single channel bandwidth operation for real world applications. This mode is used when only a single DIMM is installed or the memory capacities are unequal. Technology and device width can vary from one channel to the other. If different speed DIMMs are used between channels, the slowest memory timing will be used.

Dynamic Video Memory Technology (DVMT)
DVMT enables enhanced graphics and memory performance through Direct AGP, and highly efficient memory utilization. DVMT ensures the most efficient use of available system memory for maximum 2-D/3-D graphics performance. Up to 256 MB of system memory can be allocated to DVMT on systems that have 512 MB or more of total system memory installed. Up to 128 MB can be allocated to DVMT on systems that have 256 MB but less than 512 MB of total installed system memory. Up to 64 MB can be allocated to DVMT when less than 256 MB of system memory is installed. DVMT returns system memory back to the operating system when the additional system memory is no longer required by the graphics subsystem.
18
Product Description
DVMT will always use a minimal fixed portion of system physical memory (as set in the BIOS Setup program) for compatibility with legacy applications. An example of this would be when using VGA graphics under DOS. Once loaded, the operating system and graphics drivers allocate additional system memory to the graphics buffer as needed for performing graphics functions.
NOTE
The use of DVMT requires operating system driver support.

Configuration Modes
A list of supported modes for the Intel GMA950 graphics controller is available as a downloadable document.
For information about Supported video modes for the board Refer to Section 1.2, page 15
1.5.2
USB
The board supports up to eight USB 2.0 ports, supports UHCI and EHCI, and uses UHCI- and EHCI-compatible drivers. The ICH7 provides the USB controller for all ports. The port arrangement is as follows: * * Four ports are implemented with dual stacked back panel connectors Four ports are routed to two separate front panel USB headers
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.

IDE Support
One parallel ATA IDE connector that supports two devices Two serial ATA IDE connectors that support one device per connector
The board provides three IDE interface connectors:
19
Intel Desktop Board D945GCPE Technical Product Specification
1.5.3.1
Parallel ATE IDE Interface
The ICH7's Parallel ATA IDE controller has one bus-mastering Parallel ATA IDE interface. The Parallel ATA IDE interface supports the following modes: * * * * * Programmed I/O (PIO): processor controls data transfer. 8237-style DMA: DMA offloads the processor, supporting transfer rates of up to 16 MB/sec. Ultra DMA: DMA protocol on IDE bus supporting host and target throttling and transfer rates of up to 33 MB/sec. ATA-66: DMA protocol on IDE bus supporting host and target throttling and transfer rates of up to 66 MB/sec. ATA-66 protocol is similar to Ultra DMA and is device driver compatible. ATA-100: DMA protocol on IDE bus allows host and target throttling. The ICH7's ATA-100 logic can achieve read transfer rates up to 100 MB/sec and write transfer rates up to 88 MB/sec.
NOTE
ATA-66 and ATA-100 are faster timings and require a specialized cable to reduce reflections, noise, and inductive coupling. The Parallel ATA IDE interface also supports ATAPI devices (such as CD-ROM drives) and ATA devices using the transfer modes. The BIOS supports Logical Block Addressing (LBA) and Extended Cylinder Head Sector (ECHS) translation modes. The drive reports the transfer rate and translation mode to the BIOS.
For information about The location of the Parallel ATA IDE connector Refer to Figure 9, page 38
1.5.3.2
Serial ATA Interfaces
The ICH7's Serial ATA controller offers two independent Serial ATA ports with a theoretical maximum transfer rate of 3 Gbits/sec per port. One device can be installed on each port for a maximum of two Serial ATA devices. A point-to-point interface is used for host to device connections, unlike Parallel ATA IDE which supports a master/slave configuration and two devices per channel. For compatibility, the underlying Serial ATA functionality is transparent to the operating system. The Serial ATA controller can operate in both legacy and native modes. In legacy mode, standard IDE I/O and IRQ resources are assigned (IRQ 14 and 15). In Native mode, standard PCI Conventional bus resource steering is used. Native mode is the preferred mode for configurations using the Windows* XP operating system.
NOTE
Many Serial ATA drives use new low-voltage power connectors and require adaptors or power supplies equipped with low-voltage power connectors. For more information, see: http://www.serialata.org/

System States and Power States
Under ACPI, the operating system directs all system and device power state transitions. The operating system puts devices in and out of low-power states based on user preferences and knowledge of how devices are being used by applications. Devices that are not being used can be turned off. The operating system uses information from applications and user settings to put the system as a whole into a low-power state. Table 6 lists the power states supported by the board along with the associated system power targets. See the ACPI specification for a complete description of the various system and power states.

Wake-up Devices and Events
Table 7 lists the devices or specific events that can wake the computer from specific states. Table 7. Wake-up Devices and Events
These devices/events can wake up the computer... LAN PME# signal Power switch PS/2 devices RTC alarm USB WAKE# signal Note: ...from this state S1, S3, S4, S5 (Note) S1, S3, S4 (LAN only), S5 (LAN only) (Note) S1, S3, S4, S5 S1, S3 S1, S3, S4, S5 S1, S3 S1, S3, S4, S5
For LAN and PME# signal, S5 is disabled by default in the BIOS Setup program. Setting this option to Power On will enable a wake-up event from LAN in the S5 state.
NOTE
The use of these wake-up events from an ACPI state requires an operating system that provides full ACPI support. In addition, software, drivers, and peripherals must fully support ACPI wake events.
1.10.2
Hardware Support
CAUTION
Ensure that the power supply provides adequate +5 V standby current if LAN wake capabilities and Instantly Available PC technology features are used. Failure to do so can damage the power supply. The total amount of standby current required depends on the wake devices supported and manufacturing options. The board provides several power management hardware features, including: * * * * * * * Power connector Fan headers LAN wake capabilities Instantly Available PC technology Wake from USB Wake from PS/2 keyboard PME# signal wake-up support
LAN wake capabilities and Instantly Available PC technology require power from the +5 V standby line.

Intel Desktop Board D945GCPE Technical Product Specification
NOTE
The use of Wake from USB from an ACPI state requires an operating system that provides full ACPI support.
1.10.2.1
Power Connector
ATX12V-compliant power supplies can turn off the system power through system control. When an ACPI-enabled system receives the correct command, the power supply removes all non-standby voltages. When resuming from an AC power failure, the computer returns to the power state it was in before power was interrupted (on or off). The computer's response can be set using the Last Power State feature in the BIOS Setup program's Boot menu.
For information about The location of the main power connector The signal names of the main power connector Refer to Figure 9, page 38 Table 15, page 41

Fan Headers
The function/operation of the fan headers is as follows: The fans are on when the board is in the S0 or S1 state. The fans are off when the board is off or in the S3, S4, or S5 state. Each fan header is wired to a fan tachometer input of the Legacy I/O controller for hardware monitoring and fan control. All fan headers support closed-loop fan control that can adjust the fan speed or switch the fan on or off as needed. All fan headers have a +12 V DC connection.

LAN Wake Capabilities
CAUTION
For LAN wake capabilities, the +5 V standby line for the power supply must be capable of providing adequate +5 V standby current. Failure to provide adequate standby current when implementing LAN wake capabilities can damage the power supply. LAN wake capabilities enable remote wake-up of the computer through a network. The LAN network adapter monitors network traffic at the Media Independent Interface. Upon detecting a Magic Packet* frame, the LAN subsystem asserts a wake-up signal that powers up the computer. Depending on the LAN implementation, the board supports LAN wake capabilities with ACPI in the following ways: * * The PCI Conventional bus PME# signal for PCI 2.3 compliant LAN designs The onboard LAN subsystem
1.10.2.4
Instantly Available PC Technology
CAUTION
For Instantly Available PC technology, the +5 V standby line for the power supply must be capable of providing adequate +5 V standby current. Failure to provide adequate standby current when implementing Instantly Available PC technology can damage the power supply. Instantly Available PC technology enables the board to enter the ACPI S3 (Suspend-toRAM) sleep-state. While in the S3 sleep-state, the computer will appear to be off (the power supply is off, and the front panel LED is amber if dual colored, or off if single colored.) When signaled by a wake-up device or event, the system quickly returns to its last known wake state. Table 7 on page 29 lists the devices and events that can wake the computer from the S3 state. The board supports the PCI Bus Power Management Interface Specification. Add-in boards that also support this specification can participate in power management and can be used to wake the computer. The use of Instantly Available PC technology requires operating system support and PCI 2.3 compliant add-in cards and drivers.

Wake from USB
USB bus activity wakes the computer from ACPI S1 or S3 states.
NOTE
Wake from USB requires the use of a USB peripheral that supports Wake from USB.
1.10.2.6
Wake from PS/2 Devices
PS/2 device activity wakes the computer from an ACPI S1 or S3 state.
1.10.2.7
PME# Signal Wake-up Support

Memory Resources
Addressable Memory
The board utilizes 2 GB of addressable system memory. Typically the address space that is allocated for PCI Conventional bus add-in cards, BIOS (SPI Flash), and chipset overhead resides above the top of DRAM (total system memory). On a system that has 2 GB of system memory installed, it is not possible to use all of the installed memory due to system address space being allocated for other system critical functions. These functions include the following: * * * * * * * BIOS/ SPI Flash (4 MB) Local APIC (19 MB) Digital Media Interface (40 MB) Front side bus interrupts (17 MB) PCI Express configuration space (256 MB) GMCH base address registers and internal graphics ranges Memory-mapped I/O that is dynamically allocated for PCI Conventional add-in cards
34
Technical Reference
The amount of installed memory that can be used will vary based on add-in cards and BIOS settings. Figure 7 shows a schematic of the system memory map. All installed system memory can be used when there is no overlap of system addresses.

Thermal Considerations
CAUTION
A chassis with a maximum internal ambient temperature of 38 oC at the processor fan inlet is a requirement. Use a processor heatsink that provides omni-directional airflow to maintain required airflow across the processor voltage regulator area.
CAUTION
Failure to ensure appropriate airflow may result in reduced performance of both the processor and/or voltage regulator or, in some instances, damage to the board. For a list of chassis that have been tested with Intel desktop boards please refer to the following website: http://developer.intel.com/design/motherbd/cooling.htm All responsibility for determining the adequacy of any thermal or system design remains solely with the reader. Intel makes no warranties or representations that merely following the instructions presented in this document will result in a system with adequate thermal performance.

3.1
Introduction
The boards use an Intel BIOS that is stored in the Serial Peripheral Interface Flash Memory (SPI Flash) and can be updated using a disk-based program. The SPI Flash contains the BIOS Setup program, POST, the PCI auto-configuration utility, and Plug and Play support. The BIOS displays a message during POST identifying the type of BIOS and a revision code. The initial production BIOSs are identified as PE94510M.86A. When the BIOS Setup configuration jumper is set to configure mode and the computer is powered-up, the BIOS compares the processor version and the microcode version in the BIOS and reports if the two match. The BIOS Setup program can be used to view and change the BIOS settings for the computer. The BIOS Setup program is accessed by pressing the key after the Power-On Self-Test (POST) memory test begins and before the operating system boot begins. The menu bar is shown below. Maintenance Main Advanced Security Power Boot Exit
NOTE
The maintenance menu is displayed only when the Desktop Board is in configure mode. Section 2.3 on page 46 shows how to put the Desktop Board in configure mode.

BIOS Flash Memory Organization
The Serial Peripheral Interface Flash Memory (SPI Flash) includes a 4 Mbit (512 KB) flash memory device.
3.3
3.3.1
Resource Configuration
PCI Autoconfiguration
The BIOS can automatically configure PCI devices. PCI devices may be onboard or add-in cards. Autoconfiguration lets a user insert or remove PCI cards without having to configure the system. When a user turns on the system after adding a PCI card, the BIOS automatically configures interrupts, the I/O space, and other system resources. Any interrupts set to Available in Setup are considered to be available for use by the add-in card.
56
Overview of BIOS Features
3.3.2
PCI IDE Support
If you select Auto in the BIOS Setup program, the BIOS automatically sets up the PCI IDE connector with independent I/O channel support. The IDE interface supports hard drives up to ATA-66/100 and recognizes any ATAPI compliant devices, including CD-ROM drives, tape drives, and Ultra DMA drives. The interface also supports second-generation SATA drives. The BIOS determines the capabilities of each drive and configures them to optimize capacity and performance. To take advantage of the high capacities typically available today, hard drives are automatically configured for Logical Block Addressing (LBA) and to PIO Mode 3 or 4, depending on the capability of the drive. You can override the auto-configuration options by specifying manual configuration in the BIOS Setup program. To use ATA-66/100 features the following items are required: * * * An ATA-66/100 peripheral device An ATA-66/100 compatible cable ATA-66/100 operating system device drivers
NOTE
Do not connect an ATA device as a slave on the same IDE cable as an ATAPI master device. For example, do not connect an ATA hard drive as a slave to an ATAPI CD-ROM drive.
3.4
System Management BIOS (SMBIOS)
SMBIOS is a Desktop Management Interface (DMI) compliant method for managing computers in a managed network. The main component of SMBIOS is the Management Information Format (MIF) database, which contains information about the computing system and its components. Using SMBIOS, a system administrator can obtain the system types, capabilities, operational status, and installation dates for system components. The MIF database defines the data and provides the method for accessing this information. The BIOS enables applications such as third-party management software to use SMBIOS. The BIOS stores and reports the following SMBIOS information: * * * * BIOS data, such as the BIOS revision level Fixed-system data, such as peripherals, serial numbers, and asset tags Resource data, such as memory size, cache size, and processor speed Dynamic data, such as event detection and error logging
Non-Plug and Play operating systems require an additional interface for obtaining the SMBIOS information. The BIOS supports an SMBIOS table interface for such operating systems. Using this support, an SMBIOS service-level application running on a non-Plug and Play operating system can obtain the SMBIOS information. Additional board information can be found in the BIOS under the Additional Information header under the Main BIOS page.

BIOS Updates
Intel(R) Express BIOS Update utility, which enables automated updating while in the Windows environment. Using this utility, the BIOS can be updated from a file on a hard disk, a 1.44 MB diskette, or a CD-ROM, or from the file location on the Web. Intel(R) Flash Memory Update Utility, which requires creation of a boot diskette and manual rebooting of the system. Using this utility, the BIOS can be updated from a file on a 1.44 MB diskette (from a legacy diskette drive or an LS-120 diskette drive) or a CD-ROM.
The BIOS can be updated using either of the following utilities, which are available on the Intel World Wide Web site:
*
Both utilities verify that the updated BIOS matches the target system to prevent accidentally installing an incompatible BIOS.
NOTE
Review the instructions distributed with the upgrade utility before attempting a BIOS update.
For information about The Intel World Wide Web site Refer to Section 1.2, page 15
3.5.1
Language Support
The BIOS Setup program and help messages are supported in US English. Additional languages are available in the Integrator's Toolkit utility. Check the Intel website for details.
3.5.2
Custom Splash Screen
During POST, an Intel(R) splash screen is displayed by default. This splash screen can be augmented with a custom splash screen. The Integrator's Toolkit that is available from Intel can be used to create a custom splash screen.
NOTE
If you add a custom splash screen, it will share space with the Intel branded logo.
For information about The Intel World Wide Web site Refer to Section 1.2, page 15

Overview of BIOS Features
3.6
Legacy USB Support
Legacy USB support enables USB devices to be used even when the operating system's USB drivers are not yet available. Legacy USB support is used to access the BIOS Setup program, and to install an operating system that supports USB. Legacy USB support operates as follows: 1. When you apply power to the computer, legacy support is disabled. 2. POST begins. 3. Legacy USB support is enabled by the BIOS allowing you to use a USB keyboard to enter and configure the BIOS Setup program and the maintenance menu. 4. POST completes. 5. The operating system loads. While the operating system is loading, USB keyboards and mice are recognized and may be used to configure the operating system. 6. After the operating system loads the USB drivers, all legacy and non-legacy USB devices are recognized by the operating system, and Legacy USB support from the BIOS is no longer used. To install an operating system that supports USB, follow the operating system's installation instructions.
3.7
Boot Options
In the BIOS Setup program, the user can choose to boot from a diskette drive, hard drives, CD-ROM, or the network. The default setting is for the diskette drive to be the first boot device, the hard drive second, and the ATAPI CD-ROM third. The fourth device is disabled.
3.7.1
CD-ROM Boot
Booting from CD-ROM is supported in compliance to the El Torito bootable CD-ROM format specification. Under the Boot menu in the BIOS Setup program, ATAPI CDROM is listed as a boot device. Boot devices are defined in priority order. Accordingly, if there is not a bootable CD in the CD-ROM drive, the system will attempt to boot from the next defined drive.
3.7.2
Network Boot
The network can be selected as a boot device. This selection allows booting from the onboard LAN or a network add-in card with a remote boot ROM installed. Pressing the key during POST automatically forces booting from the LAN. To use this key during POST, the User Access Level in the BIOS Setup program's Security menu must be set to Full.
59
Intel Desktop Board D945GCPE Technical Product Specification
3.7.3
Booting Without Attached Devices
For use in embedded applications, the BIOS has been designed so that after passing the POST, the operating system loader is invoked even if the following devices are not present: * * * Video adapter Keyboard Mouse
3.7.4
Changing the Default Boot Device During POST
Pressing the key during POST causes a boot device menu to be displayed. This menu displays the list of available boot devices (as set in the BIOS setup program's Boot Device Priority Submenu). Table 28 lists the boot device menu options. Table 28. Boot Device Menu Options

Adjusting Boot Speed
Selecting and configuring peripherals properly Optimized BIOS boot parameters
These factors affect system boot speed:
3.8.1
* * *
Peripheral Selection and Configuration
Choose a hard drive with parameters such as "power-up to data ready" less than eight seconds, that minimize hard drive startup delays. Select a CD-ROM drive with a fast initialization rate. This rate can influence POST execution time. Eliminate unnecessary add-in adapter features, such as logo displays, screen repaints, or mode changes in POST. These features may add time to the boot process. Try different monitors. Some monitors initialize and communicate with the BIOS more quickly, which enables the system to boot more quickly.
The following techniques help improve system boot speed:
*
3.8.2
BIOS Boot Optimizations
Use of the following BIOS Setup program settings reduces the POST execution time. In the Boot Menu: * Set the hard disk drive as the first boot device. As a result, the POST does not first seek a diskette drive, which saves about one second from the POST execution time. Disable Quiet Boot, which eliminates display of the logo splash screen. This could save several seconds of painting complex graphic images and changing video modes.
*
In the Peripheral Configuration submenu, disable the LAN device if it will not be used. This can reduce up to four seconds of option ROM boot time.
NOTE
It is possible to optimize the boot process to the point where the system boots so quickly that the Intel logo screen (or a custom logo splash screen) will not be seen. Monitors and hard disk drives with minimum initialization times can also contribute to a boot time that might be so fast that necessary logo screens and POST messages cannot be seen. This boot time may be so fast that some drives might be not be initialized at all. If this condition should occur, it is possible to introduce a programmable delay ranging from three to 30 seconds (using the Hard Disk Pre-Delay feature of the Advanced Menu in the Drive Configuration Submenu of the BIOS Setup program).
61
Intel Desktop Board D945GCPE Technical Product Specification
3.9
BIOS Security Features
The BIOS includes security features that restrict access to the BIOS Setup program and who can boot the computer. A supervisor password and a user password can be set for the BIOS Setup program and for booting the computer, with the following restrictions: * * * * The supervisor password gives unrestricted access to view and change all the Setup options in the BIOS Setup program. This is the supervisor mode. The user password gives restricted access to view and change Setup options in the BIOS Setup program. This is the user mode. If only the supervisor password is set, pressing the key at the password prompt of the BIOS Setup program allows the user restricted access to Setup. If both the supervisor and user passwords are set, users can enter either the supervisor password or the user password to access Setup. Users have access to Setup respective to which password is entered. Setting the user password restricts who can boot the computer. The password prompt will be displayed before the computer is booted. If only the supervisor password is set, the computer boots without asking for a password. If both passwords are set, the user can enter either password to boot the computer. For enhanced security, use different passwords for the supervisor and user passwords. Valid password characters are A-Z, a-z, and 0-9. Passwords may be up to 16 characters in length.

Port 80h POST Codes
During the POST, the BIOS generates diagnostic progress codes (POST-codes) to I/O port 80h. If the POST fails, execution stops and the last POST code generated is left at port 80h. This code is useful for determining the point where an error occurred. Displaying the POST-codes requires a PCI bus add-in card, often called a POST card. The POST card can decode the port and display the contents on a medium such as a seven-segment display.
NOTE
The POST card must be installed in PCI bus connector 1. The following tables provide information about the POST codes generated by the BIOS: * * * Table 32 lists the Port 80h POST code ranges Table 33 lists the Port 80h POST codes themselves Table 34 lists the Port 80h POST sequence

5.1.3.3
Lead Free Desktop Board
This Desktop Board is a European Union Restriction of Hazardous Substances (EU RoHS Directive 2002/95/EC) compliant product. EU RoHS restricts the use of six materials. One of the six restricted materials is lead. This Desktop Board is lead free although certain discrete components used on the board contain a small amount of lead which is necessary for component performance and/or reliability. This Desktop Board is referred to as "Lead-free second level interconnect." The board substrate and the solder connections from the board to the components (second-level connections) are all lead free. China bans the same substances and has the same limits as EU RoHS; however it requires different product marking and controlled substance information. The required mark shows the Environmental Friendly Usage Period (EFUP). The EFUP is defined as the number of years for which controlled listed substances will not leak or chemically deteriorate while in the product. Table 36 shows the various forms of the "Lead-Free 2nd Level Interconnect" mark as it appears on the board and accompanying collateral. Table 36. Lead-Free Board Markings
Description
Lead-Free 2 Level Interconnect: This symbol is used to identify electrical and electronic assemblies and components in which the lead (Pb) concentration level in the desktop board substrate and the solder connections from the board to the components (second-level interconnect) is not greater than 0.1% by weight (1000 ppm).
