• Intel 82865G Graphics and Memory Controller Hub (GMCH) with Accelerated Hub Architecture (AHA) bus
• Intel 82801EB I/O Controller Hub (ICH5) with AHA bus
• Firmware Hub (FWH) The GMCH is a centralized controller for the system bus, the memory bus, and the Accelerated Hub Architecture interface. The ICH5 is a centralized controller for the board’s I/O paths. The FWH provides the nonvolatile storage of the BIOS. For information about Refer to The Intel 865G chipset http://developer.intel.com/ Resources used by the chipset Chapter 2

1.5.1 Intel 865G Graphics Subsystem

The Intel 865G chipset uses the Intel Extreme Graphics 2 controller (contained within the 82865G GMCH).

1.5.1.1 Intel® Extreme Graphics 2 Controller

The Intel Extreme Graphics 2 controller features the following:

• Integrated graphics controller ⎯ 32 bpp (Bits Per Pixel) graphics engine ⎯ 266 MHz core frequency ⎯ 256-bit 2-D engine ⎯ 32-bit 3-D engine ⎯ Motion video acceleration
• High performance 3-D setup and render engine
• High quality/performance texture engine
• Display ⎯ Integrated 24-bit 350 MHz RAMDAC ⎯ DDC2B compliant interface
• Hardware motion compensation for software MPEG2 decode
• Dynamic Video Memory Technology (DVMT) support up to 64 MB For information about Refer to DVMT Section 1.5.1.3, page 27 Obtaining graphics software and utilities Section 1.2, page 15

1.5.1.3 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 64 MB of system memory can be allocated to DVMT on systems that have 256 MB or more of total system memory installed. Up to 32 MB can be allocated to DVMT on systems that have 128 MB but less than 256 MB of total installed system memory. Up to 8 MB can be allocated to DVMT when less than 128 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. 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.

1.5.1.4 Zone Rendering Technology (ZRT)

The Intel Extreme Graphics 2 Controller supports Zone Rendering Technology (ZRT). ZRT is a process by which the screen is divided into several zones. Each zone is completely cached and rendered on chip before being written to the frame buffer. The benefits of ZRT include the following:

• Increased memory efficiency via better localization of data
• Increased on-chip processing speed due to decreased wait time for data
• Increased effective pixel fill rates
• Increased headroom for larger resolution and color depth
• Reduced power as a result of decreased memory bandwidth
• Reduction in depth and color bandwidth associated with conventional rendering

1.5.1.5 Rapid Pixel and Text Rendering (RPTR)

The Rapid Pixel and Text Rendering Engine (RPTR) architecture utilizes special pipelines that allow 2D and 3D operations to overlap. By providing 8X compression, the RPTR engine reduces the memory bandwidth required to read texture memory, and reduces the amount of memory required for texture storage. A dedicated, non-blocking, multi-tier cache is provided for textures, colors, Z and vertex rendering. With single-pass, quad texture support, the drivers can submit up to four textures that pass to the graphics engine concurrently. The graphics core can switch between 2D and 3D operations without having to complete all operations of the same mode, which minimizes the overhead time required in switching between modes.

Intel Desktop Board D865GSA Technical Product Specification A 2D Block Level Transfer (BLT) in the RPTR engine is extended to 256-bit, which supports fast blitter fill rate. This enables the blitter sequence of the same addresses to access the cache and offloads the memory bandwidth required to support blitter fill rate. Then the cache is emptied automatically when the sequence of operations are complete.

1.5.1.6 Intelligent Memory Management (IMM)

Intelligent Memory Management (IMM) technology is Intel’s unique UMA memory manager architecture, consisting of these key elements:

• Tiled memory addressing capability
• Deep display buffer implementation
• Dynamic data management scheme The memory addressing allows address remapping in the hardware for all graphics surfaces including textures, frame buffer, Z buffer, and video surfaces. Deep display buffers and dedicated screen refreshes improve visual performance, while the dynamic data management scheme manages burst size and page closing policies for memory accesses. IMM reduces the aggregate processor latency and allows longer in-page bursts for higher system performance. IMM also increases page coherency and improves memory efficiency in texture loads, 2D blitters, color/Z, MPEG2 motion compression, and other operations.

1.5.1.7 Video Mixing Renderer (VMR)

The Intel Extreme Graphics 2 controller features VMR technology. VMR is a process where various data types can be blended together before being displayed. VMR allows applications to bend and twist images such as 3D textures so that special effects such as wipes, spins, and fades can be achieved.

1.5.1.8 PC/VCR Time Shifted Viewing

PC/VCR requires a TV-tuner add-in card and a third party application. PC/VCR time shifted viewing allows the user to view and digitally record video pictures on their PC. Users can view stored images while recording and by using time-shifted viewing they can pause, resume, replay, and catch up to real time. The Intel Pentium 4 processor in combination with the Intel 82865G GMCH optimizes performance so that the video output is smooth without leaving any visual artifacts. Video tearing and corruption is prevented by the use of multiple buffers within the Intel Extreme Graphics 2 controller.

1.5.1.9 Bi-cubic Filtering

Bi-cubic filtering is a new 4X4 filter that allows images to be generated more smoothly in the 3D pipeline. The bi-cubic filter can be used to improve image quality for all 3D texture engine components.

1.5.1.10 AGP Digital Display (ADD) Card Support

The GMCH routes two 12-bit multiplexed DVO ports that are each capable of driving a 165 MHz pixel clock to the AGP connector. The DVO ports can be paired for dual channel mode. In dual channel mode, the GMCH is capable of driving a 24-bit 330 MHz pixel clock. When an AGP add-in card is used, the Intel Extreme Graphics 2 controller is disabled and the AGP connector operates in AGP mode. When an ADD card is detected, the Intel Extreme Graphics 2 controller is enabled and the AGP connector is configured for DVO mode. DVO mode enables the DVO ports to be accessed by an ADD card. ADD cards can support up to two display devices with the following configurations:

• TV-Out
• Transition Minimized Differential Signaling (TMDS)
• Low Voltage Differential Signaling (LVDS)
• Single device operating in dual channel mode # INTEGRATOR’S NOTES
• Synchronous display is not supported when one of the display devices is a TV.
• Synchronous display with two digital displays is not supported.
• Digital Visual Interface (DVI) support is present only when an ADD card is installed. The AGP connector supports the following:
• 4x, 8x AGP 3.0 add-in cards with 0.8 V I/O
• 1x, 4x AGP 2.0 add-in cards with 1.5 V I/O
• AGP Digital Display (ADD) cards AGP is a high-performance interface for graphics-intensive applications, such as 3D applications. While based on the PCI Local Bus Specification, Rev. 2.2, AGP is independent of the PCI bus and is intended for exclusive use with graphical display devices. AGP overcomes certain limitations of the PCI bus related to handling large amounts of graphics data with the following features:
• Pipelined memory read and write operations that hide memory access latency
• Demultiplexing of address and data on the bus for nearly 100 percent efficiency # INTEGRATOR’S NOTES
• AGP 2x operation is not supported.
• Install memory in the DIMM sockets prior to installing the AGP video card to avoid interference with the memory retention mechanism.
• The AGP connector is keyed for Universal 0.8 V AGP 3.0 cards or 1.5 V AGP 2.0 cards only. Do not attempt to install a legacy 3.3 V AGP card. The AGP connector is not mechanically compatible with legacy 3.3 V AGP cards. For information about Refer to The location of the AGP connector on the D865GSA board Figure 11, page 54

Intel Desktop Board D865GSA Technical Product Specification

1.5.3 USB

The board supports up to eight USB 2.0 ports, supports UHCI and EHCI, and uses UHCI- and EHCI-compatible drivers. The ICH5 provides the USB controller for all ports. The port arrangement is as follows:

• Four ports are implemented with stacked back panel connectors, adjacent to the audio connectors
• Four ports are routed to two separate front panel USB connectors 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. For information about Refer to The location of the USB connectors on the back panel Figure 10, page 53 The location of the front panel USB connectors Figure 11, page 54

1.5.4 IDE Support

The board provides four IDE interface connectors:

• Two Parallel ATA IDE connectors, which support a total of four devices (two per connector)
• Two Serial ATA IDE connectors, which support one device per connector

1.5.4.1 Parallel ATA IDE Interfaces

The ICH5’s Parallel ATA IDE controller has two independent bus-mastering Parallel ATA IDE interfaces that can be independently enabled. The Parallel ATA IDE interfaces support 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 ICH5’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 interfaces also support ATAPI devices (such as CD-ROM drives) and ATA devices. 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 Refer to The location of the Parallel ATA IDE connectors Figure 11, page 54

1.5.4.2 Serial ATA Interfaces

The ICH5’s Serial ATA controller offers two independent Serial ATA ports with a theoretical maximum transfer rate of 150 MB/s 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 resource steering is used. Native mode is the preferred mode for configurations using the Windows* XP and Windows 2000 operating systems. NOTE Many Serial ATA drives use new low-voltage power connectors and require adaptors or power supplies equipped with low-voltage power connectors.

1.10.2 Hardware Support

on the wake devices supported and manufacturing options.

• Power connector
• Fan connectors
• LAN wake capabilities
• Instantly Available PC technology
• Resume on Ring
• 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. The sections discussing these features describe the incremental standby power requirements for each.

Intel Desktop Board D865GSA Technical Product Specification Resume on Ring enables telephony devices to access the computer when it is in a power-managed state. The method used depends on the type of telephony device (external or internal). NOTE The use of Resume on Ring and Wake from USB technologies 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 Refer to The location of the power connector Figure 11, page 54 The signal names of the power connector Table 29, page 57

1.10.2.2 Fan Connectors

The function/operation of the fan connectors 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 connector is wired to a fan tachometer input of the hardware monitoring and fan control ASIC.
• All fan connectors support closed-loop fan control that can adjust the fan speed or switch the fan on or off as needed.
• All fan connectors have a +12 V DC connection. For information about Refer to The location of the fan connectors Figure 11, page 54 The signal names of the processor fan connector Table 23, page 56 The signal names of the chassis fan connectors Table 22, page 56

1.10.2.3 LAN Wake Capabilities

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 subsystem PCI bus 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 bus PME# signal for PCI 2.3 compliant LAN designs
• The onboard LAN subsystem

1.10.2.4 Instantly Available PC Technology

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-to- RAM) 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 14 on page 43 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.

1.10.2.5 Resume on Ring

The operation of Resume on Ring can be summarized as follows:

• Resumes operation from ACPI S1 or S3 states
• Detects incoming call similarly for external and internal modems
• Requires modem interrupt be unmasked for correct operation

1.10.2.6 Wake from USB

USB bus activity wakes the computer from ACPI S1 or S3 states.

Wake from USB requires the use of a USB peripheral that supports Wake from USB.

1.10.2.7 Wake from PS/2 Devices

PS/2 device activity wakes the computer from an ACPI S1 or S3 state.

2.6 PCI Interrupt Routing Map

• 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 ICH5 has eight Programmable Interrupt Request (PIRQ) input signals. All PCI interrupt sources either onboard or from a PCI add-in card connect to one of these PIRQ signals. Some PCI interrupt sources are electrically tied together on the board and therefore share the same interrupt. Table 20 shows an example of how the PIRQ signals are routed. For example, using Table 20 as a reference, assume an add-in card using INTA is plugged into PCI bus connector 3. In PCI bus connector 3, INTA is connected to PIRQB, which is already connected to the ICH5 audio controller. The add-in card in PCI bus connector 3 now shares an interrupt with the onboard interrupt source.

2.7.2.2 Add-in Card Connectors

The board has the following add-in card connectors:

• One Universal 0.8 V / 1.5 V AGP 3.0 connector supporting 1x, 4x, and 8x AGP cards
• Three PCI Conventional (rev 2.3 compliant) bus add-in card connectors. 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 board. Note the following considerations for the PCI Conventional bus connectors:
• 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 boards. 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.

What This Chapter Contains

3.1 Introduction

The board uses an Intel/AMI BIOS that is stored in the Firmware Hub (FWH) and can be updated using a disk-based program. The FWH 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 SA86510A.86A. When the BIOS Setup configuration jumper is set to configure mode and the computer is powered-up, the BIOS compares the CPU 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 <F2> 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 board is in configure mode. Section 2.8 on page 61 shows how to put the board in configure mode.

3.2 BIOS Flash Memory Organization

The Firmware Hub (FWH) includes a 4 Mbit (512 KB) symmetrical flash memory device.

3.3 Resource Configuration

3.3.1 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.

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 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, 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.

Intel Desktop Board D865GSA Technical Product Specification

3.5 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. By default, Legacy USB support is set to Enabled. 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. (Keyboards and mice are not recognized during this period if Legacy USB support was set to Disabled in the BIOS Setup program.) 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, verify that Legacy USB support in the BIOS Setup program is set to Enabled and follow the operating system’s installation instructions.

3.6 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 (from a legacy diskette drive or an LS-120 diskette drive) or a CD-ROM. 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 Refer to The Intel World Wide Web site Section 1.2, page 15

3.6.1 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.

3.6.2 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 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 Refer to The Intel World Wide Web site Section 1.2, page 15

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 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.

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 <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.

3.7.3 Booting Without Attached Devices

• Video adapter
• Keyboard
• Mouse

Boot Device Priority Submenu). Table 44 lists the boot device menu options. Table 44. Boot Device Menu Options

3.8 Fast Booting Systems with Intel® Rapid BIOS

• Selecting and configuring peripherals properly
• Using an optimized BIOS, such as the Intel® Rapid BIOS

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.

3.8.2 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. 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).

3.9 BIOS Security Features

• 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.

Table 45. Supervisor and User Password Functions Note: If no password is set, any user can change all Setup options.

4.2 Port 80h POST Codes

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 must be installed in PCI bus connector 1. The tables below offer descriptions of the POST codes generated by the BIOS.
