CAUTIONS
The procedures in this chapter assume familiarity with the general terminology associated with personal computers and with the safety practices and regulatory compliance required for using and modifying electronic equipment. Disconnect the computer from its power source and from any telecommunications links, networks, or modems before performing any of the procedures described in this chapter. Failure to disconnect power, telecommunications links, networks, or modems before you open the computer or perform any procedures can result in personal injury or equipment damage. Some circuitry on the board can continue to operate even though the front panel power button is off. Follow these guidelines before you begin: Always follow the steps in each procedure in the correct order. Set up a log to record information about your computer, such as model, serial numbers, installed options, and configuration information. Electrostatic discharge (ESD) can damage components. Perform the procedures described in this chapter only at an ESD workstation using an antistatic wrist strap and a conductive foam pad. If such a station is not available, you can provide some ESD protection by wearing an antistatic wrist strap and attaching it to a metal part of the computer chassis.

Figure 26. Auxiliary Power Output Connector
The D955XBK board includes a male 1x4 power connector that can be used to provide power for internal chassis lighting or additional fans using less that 1.5 A. The 1x4 connector is off by default. You can turn on/off the connector from within the BIOS Setup program under Advanced Peripheral Configuration Auxiliary Power.
Use of this connector requires an ATX12V power supply with a 24-pin (2x12) main power cable. If a power supply with a 20-pin (2x10) main power cable is used, the auxiliary power output connector may not function. The connector circuitry includes overcurrent protection components that limit the current draw to a maximum of 1.5 A.
Do not use a Y-adapter, power splitter, or SATA power adapter to attach storage devices (such as hard disk drives or CD/DVD drives) to this connector. This connector will NOT provide adequate power for storage devices.

Connecting Power Cables

Failure to use the appropriate power supply and/or not connecting the 12 V (2x4) power connector to the desktop board may result in damage to the board or the system may not function properly. See Table 3 on page 13 for power supply requirements. The 2x12 main power connector on the desktop board is backwards compatible with ATX12V power supplies with 2x10 power connections. Use of the 1x4 power connection is recommended with ATX12V power supplies with 2x10 connections when using PCI Express video cards that can consume up to 75 W.

2.6 PCI Conventional Interrupt Routing Map
This section describes interrupt sharing and how the interrupt signals are connected between the PCI Conventional bus connectors and onboard PCI Conventional devices. The PCI Conventional specification describes how interrupts can be shared between devices attached to the PCI Conventional bus. In most cases, the small amount of latency added by interrupt sharing does not affect the operation or throughput of the devices. In some special cases where maximum performance is needed from a device, a PCI Conventional device should not share an interrupt with other PCI Conventional devices. Use the following information to avoid sharing an interrupt with a PCI Conventional add-in card. PCI Conventional devices are categorized as follows to specify their interrupt grouping: INTA: By default, all add-in cards that require only one interrupt are in this category. For almost all cards that require more than one interrupt, the first interrupt on the card is also classified as INTA. INTB: Generally, the second interrupt on add-in cards that require two or more interrupts is classified as INTB. (This is not an absolute requirement.) INTC and INTD: Generally, a third interrupt on add-in cards is classified as INTC and a fourth interrupt is classified as INTD.

The ICH7-R has eight Programmable Interrupt Request (PIRQ) input signals. All PCI Conventional interrupt sources either onboard or from a PCI Conventional add-in card connect to one of these PIRQ signals. Some PCI Conventional interrupt sources are electrically tied together on the board and therefore share the same interrupt. Table 14 shows an example of how the PIRQ signals are routed. For example, using Table 14 as a reference, assume an add-in card using INTA is plugged into PCI Conventional bus connector 3. In PCI bus connector 3, INTA is connected to PIRQB, which is already connected to the ICH7-R audio controller. The add-in card in PCI Conventional bus connector 3 now shares an interrupt with the onboard interrupt source.

Table 14.

ICH7-R PIRQ Signal Name PIRQA PIRQB INTA INTD INTC INTD INTC INTA INTB INTA INTB INTB INTA INTC INTD PIRQC PIRQD PIRQE PIRQF PIRQG PIRQH
PCI Interrupt Source IEEE-1394a/b controller PCI bus connector 1 PCI bus connector 2 PCI bus connector 3
In PIC mode, the ICH7-R can connect each PIRQ line internally to one of the IRQ signals (3, 4, 5, 6, 7, 9, 10, 11, 12, 14, and 15). Typically, a device that does not share a PIRQ line will have a unique interrupt. However, in certain interrupt-constrained situations, it is possible for two or more of the PIRQ lines to be connected to the same IRQ signal. Refer to Table 13 for the allocation of PIRQ lines to IRQ signals in APIC mode. PCI interrupt assignments to the USB ports, Serial ATA ports, and PCI Express ports are dynamic.

2.7 Connectors

Only the following connectors have overcurrent protection: back panel USB, front panel USB, and PS/2. The other internal connectors are not overcurrent protected and should connect only to devices inside the computers chassis, such as fans and internal peripherals. Do not use these connectors to power devices external to the computers chassis. A fault in the load presented by the external devices could cause damage to the computer, the power cable, and the external devices themselves. This section describes the boards connectors. The connectors can be divided into these groups: Back panel I/O connectors Component-side I/O connectors (see page 56)

The SMBus is routed to PCI Conventional bus connector 2 only (ATX expansion slot 6). PCI Conventional bus add-in cards with SMBus support can access sensor data and other information residing on the Desktop Board. All of the PCI Conventional bus connectors are bus master capable. SMBus signals are routed to PCI Conventional bus connector 2. This enables PCI Conventional bus add-in boards with SMBus support to access sensor data on the Desktop Board. The specific SMBus signals are as follows: The SMBus clock line is connected to pin A40. The SMBus data line is connected to pin A41.
The board has the following add-in card connectors:

2.8 Jumper Block

Do not move the jumper with the power on. Always turn off the power and unplug the power cord from the computer before changing a jumper setting. Otherwise, the board could be damaged. Figure 23 shows the location of the jumper block. The 3-pin jumper block determines the BIOS Setup programs mode. Table 34 describes the jumper settings for the three modes: normal, configure, and recovery. When the jumper is set to configure mode and the computer is poweredup, the BIOS compares the processor version and the microcode version in the BIOS and reports if the two match.

Use a processor heatsink that provides omni-directional airflow (similar to the type shown in Figure 27) to maintain required airflow across the processor voltage regulator area.

OM16996

Figure 27. Example of a Processor Heatsink for Omni-directional Airflow
When using BIOS Setup program options to increase processor voltage and frequency above the supported ranges, the temperature in the processor voltage regulator area will rise. This area of the board (item A in Figure 28) will require increased airflow. Direct airflow over the processor voltage regulator is crucial to preventing throttling and keeping the processor voltage regulator area cool. This is particularly important when using liquid cooling. 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. Figure 28 shows the locations of the localized high temperature zones.

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.
Overview of BIOS Features
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
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.
3.3 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 clock frequency Dynamic data, such as event detection and error logging
Non-Plug and Play operating systems, such as Windows NT*, 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.

3.4 Legacy USB Support

Legacy USB support enables USB devices to be used even when the operating systems 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 systems installation instructions.

3.5 BIOS Updates

The BIOS can be updated using either of the following utilities, which are available on the Intel World Wide Web site: Intel 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 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 or a CD-ROM.
Both utilities verify that the updated BIOS matches the target system to prevent accidentally installing an incompatible BIOS.
Review the instructions distributed with the upgrade utility before attempting a BIOS update.
For information about Refer to
The Intel World Wide Web site

Section 1.2, page 15

Language Support
The BIOS Setup program and help messages are supported in US English. Additional languages are available in the Integrators Toolkit utility. Check the Intel website for details.

Custom Splash Screen

During POST, an Intel splash screen is displayed by default. This splash screen can be augmented with a custom splash screen. The Integrators Toolkit that is available from Intel can be used to create a custom splash screen.
If you add a custom splash screen, it will share space with the Intel branded logo.

3.6 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.

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 CD-ROM 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.

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 <F12> 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.

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
Changing the Default Boot Device During POST
Pressing the <F10> 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 programs Boot Device Priority Submenu). Table 44 lists the boot device menu options.

3.7 Fast Booting Systems with Intel Rapid BIOS Boot
These factors affect the amount of time for a system to complete boot process: Selecting and configuring peripherals properly Using an optimized BIOS, such as the Intel Rapid BIOS
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 reduce system boot time:

Intel Rapid BIOS Boot

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. Enable Intel Rapid BIOS Boot. This feature bypasses memory count and the search for a diskette drive.

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.
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).
3.8 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 <Enter> 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.
Table 45 shows the effects of setting the supervisor password and user password. This table is for reference only and is not displayed on the screen.
