Intel Desktop Board D845PESV Product Guide Processor CAUTION Failure to use an ATX12V power supply, or not connecting the additional power supply lead to Desktop Board D845PESV may result in damage to the desktop board and/or power supply. Desktop Board D845PESV supports a single Intel Pentium 4 processor or Intel Celeron processor. Processors are not included with the desktop board and must be purchased separately. The processor connects to the Intel desktop board through the mPGA478-pin socket.
Desktop Board Features Main Memory ✏ NOTE To be fully compliant with all applicable Intel® SDRAM memory specifications, the board should be populated with DIMMs that support the Serial Presence Detect (SPD) data structure. If your memory modules do not support SPD, you will see a notification to this effect on the screen at power up. The BIOS will attempt to configure the memory controller for normal operation.
Intel Desktop Board D845PESV Product Guide Intel® 845PE Chipset The Intel 845PE chipset consists of the following devices: • • • Intel 82845PE Memory Controller Hub (MCH) with AHA bus Intel 82801DB I/O Controller Hub (ICH4) with AHA bus Firmware Hub (FWH) Intel® 82845PE Memory Controller Hub (MCH) The MCH provides the processor, system memory, AGP, and hub interfaces in the Intel 845PE chipset platform.
Desktop Board Features Input/Output (I/O) Controller The SMSC LPC47M172 or National Semiconductor PC87372 super I/O controllers feature the following: • • • • • • • • • Low pin count (LPC) interface Two serial ports (one via a board connector) One parallel port with Extended Capabilities Port (ECP) and Enhanced Parallel Port (EPP) support Serial IRQ interface compatible with serialized IRQ support for PCI systems PS/2-style mouse and keyboard interfaces Interface for one 1.2 MB, 1.44 MB, or 2.
Intel Desktop Board D845PESV Product Guide RJ-45 LAN Connector LEDs Two LEDs are built into the RJ-45 LAN connector. Table 3 describes the LED states when the board is powered up and the LAN subsystem is operating. Table 3. RJ-45 LAN Connector LEDs LED Color LED State Indicates Green Off 10 Mbit/sec data rate is selected. On 100 Mbit/sec data rate is selected. Yellow Off LAN link is not established. On (steady state) LAN link is established.
Desktop Board Features Expansion Slots Desktop Board D845PESV has the following add-in card connectors: • • Six PCI bus add-in card connectors (SMBus routed to PCI bus connector 2) One AGP connector Accelerated Graphics Port (AGP) ✏ NOTE Desktop Board D845PESV is only compatible with 1.5 V AGP cards. AGP is a high-performance interface for graphics-intensive applications, such as 3D graphics. AGP is independent of the PCI bus and is intended for exclusive use with graphical display devices.
Intel Desktop Board D845PESV Product Guide Security Passwords The BIOS includes security features that restrict whether the BIOS Setup program can be accessed and who can boot the computer. A supervisor password and a user password can be set for the Setup and for booting the computer, with the following restrictions: • • • The supervisor password gives unrestricted access to view and change all Setup options.
Desktop Board Features CR8H1 OM14704 Figure 2. Location of Standby Power Indicator CAUTION Power supplies used with this board must be able to provide enough standby current to support the standard Instantly Available (ACPI S3 sleep state) configuration. If the standby current necessary to support multiple wake events from the PCI and/or USB buses exceeds power supply capacity, the Intel desktop board may lose register settings stored in memory.
Intel Desktop Board D845PESV Product Guide Fan Connectors Desktop Board D845PESV has two chassis fan connectors and one processor fan connector. See Figure 11 on page 33 for the location of the fan connectors. Fan Speed Control (Intel® Precision Cooling) Intel Precision Cooling automatically adjusts the chassis fan speeds depending on the system’s temperature.
Desktop Board Features Battery A battery on the Intel desktop board keeps the values in CMOS RAM and the clock current when the computer is turned off. See Chapter 2 starting on page 21 for instructions on how to replace the battery. Real-Time Clock Desktop Board D845PESV has a time-of-day clock and 100-year calendar.

Disconnect the computer’s power cord from the AC power source (wall outlet or power adapter). 3. Remove the computer cover. 4.
Intel Desktop Board D845PESV Product Guide Replacing the Battery A coin-cell battery (CR2032) powers the real-time clock and CMOS memory. When the computer is not plugged into a wall socket, the battery has an estimated life of three years. When the computer is plugged in, the standby current from the power supply extends the life of the battery. The clock is accurate to ± 13 minutes/year at 25 ºC with 3.3 VSB applied.
Installing and Replacing Desktop Board Components VORSICHT Bei falschem Einsetzen einer neuen Batterie besteht Explosionsgefahr. Die Batterie darf nur durch denselben oder einen entsprechenden, vom Hersteller empfohlenen Batterietyp ersetzt werden. Entsorgen Sie verbrauchte Batterien den Anweisungen des Herstellers entsprechend. (German) AVVERTIMENTO Esiste il pericolo di un esplosione se la pila non viene sostituita in modo corretto.
Intel Desktop Board D845PESV Product Guide To replace the battery, follow these steps: 1. Observe the precautions in “Before You Begin” (see page 21). 2. Turn off all peripheral devices connected to the computer. Disconnect the computer’s power cord from the AC power source (wall outlet or power adapter). 3. Remove the computer cover. 4. Locate the battery on the board (see Figure 13). 5. With a medium flat-bladed screwdriver, gently pry the battery free from its connector.
3 Updating the BIOS This chapter tells you how to update the BIOS by either using the Intel® Express BIOS Update utility or the Intel® Flash Memory Update Utility, and how to recover the BIOS if an update fails. Updating the BIOS with the Intel® Express BIOS Update Utility With the Intel Express BIOS Update utility you can update the system BIOS while in the Windows environment.
Intel Desktop Board D845PESV Product Guide Updating the BIOS with the Intel® Flash Memory Update Utility With the Intel Flash Memory Update Utility you can update the system BIOS from a floppy disk or other bootable media. The utility available from the Web provides a simple method for creating a bootable flash memory update floppy that will automatically update your BIOS. Obtaining the BIOS Update File You can update to a new version of the BIOS by using the BIOS update file.
Updating the BIOS Recovering the BIOS It is unlikely that anything will interrupt the BIOS update; however, if an interruption occurs, the BIOS could be damaged. The following steps explain how to recover the BIOS if an update fails. The following procedure uses recovery mode for the Setup program. See page 34 for more information on Setup modes. ✏ NOTE Because of the small amount of code available in the boot block area, there is no video support.
