Processor and Secondary Cache
The system uses an Intel Celeron, Pentium II, or Pentium III processor with an internal clock speed of 300 MHz, 333 MHz, 350 MHz, 366 MHz, 400 MHz, 433 MHz, 450 MHz, or 500 MHz (depending on type of processor and model). The processor is an advanced pipelined 32-bit addressing, 64-bit data processor designed to optimize multitasking operating systems. The 64-bit registers and data paths support 64-bit addresses and data types. To use the processors power, the system features an optimized 64-bit memory interface and 512 KB (128 KB for Celeron) of secondary write-back cache on the processor. The processor is compatible with 8-, 16-, and 32-bit software written for the Intel386, Intel486, Pentium, and Pentium Pro processors. The processor is mounted in S.E.C. cartridge with an attaching heatsink that installs as a unit in Slot 1 on the system board.

System BIOS

The ISA- and PCI-compatible BIOS is contained in a flash memory device on the system board. The BIOS provides the Power-On Self-Test (POST), the system Setup program, a PCI and IDE auto-configuration utility, and BIOS recovery code. The system BIOS is always shadowed. Shadowing allows any BIOS routine to be executed from fast 32-bit DRAM on the system board, instead of from the slower 8-bit flash device. The Flash ROM allows fast, economical BIOS upgrades. The Flash ROM is a reprogrammable EPROM containing both the system and video BIOS. Using the Flash ROM to change the ROM BIOS provides the following advantages:
T the BIOS upgrade is performed quickly and easily T the expense of replacing ROM BIOS chips is eliminated, so system
maintenance costs are reduced
T there is less chance of inadvertently damaging the system board than
when physically replacing ROMs
T new technology can be incorporated while maintaining corporate

standards

T network administrators can exercise company-wide control of BIOS
revisions. The BIOS programs execute the Power-On Self-Test, initialize processor controllers, and interact with the display, diskette drive, hard drives, communication devices, and peripherals. The system BIOS also contains the Setup utility. The POST copies the ROM BIOS into RAM (shadowing) for maximum performance.

4-12 System Board

The Flash ROM allows the system and video BIOS to be upgraded with the BIOS Update utility, without having to physically remove the ROM (see Section 2 for further information on the BIOS Update utility). The Flash ROM supports the reprogramming of the system BIOS and the video BIOS.

I/O Addresses

The processor communicates with I/O devices by I/O mapping. The hexadecimal (hex) addresses of I/O devices are listed in the following table.
Note: In Plug and Play systems, these addresses are typical but may vary by configuration. I/O Address Map
Address (Hex) 0000-000F 0020-0021 002E-002F 0040-0043 0048-004B 0064 I/O Device Name PIIX4 - DMA controller 1 (channel 0-3) PIIX4 - interrupt controller 1 Super I/O controller configuration registers PIIX4 - counter/timer 1 PIIX4 - counter/timer 2 Keyboard controller byte - reset IRQ PIIX4 - NMI, speaker control Keyboard controller, command/status byte

Glossary

access time
The time period between the supply of an access signal and the output or acceptance of the data by the addressed system. Examples are the access times for DRAMs, SRAMs, hard drives, and CD-ROM drives. Hard drive access time is the time it takes for a computer to get data from the drive. A hard drive with an 11 ms access time is fast. A CD-ROM drive with a 280-ms access time is fast.
Advanced Configuration and Power Interface. A power management specification developed by Intel, Microsoft, and Toshiba. When installed on the system, ACPI enables the operating system to control the amount of power given to each device attached to the computer. With ACPI, the operating system can turn off peripheral devices (such as CD-ROM drives) when they are not in use. As another example, ACPI enables manufacturers to produce computers that automatically power up as soon as you touch the keyboard.

Accelerated Graphics Port. A high-speed, high-performance video standard supported by a dedicated connector on the system board. The connector allows the connection of an AGP board to the system boards AGP bus. AGP boards feature 64- or 128-bit graphics acceleration with an integrated digital video engine and accelerated 3-D graphics, texture mapping, and shading functions. Fast refresh rates, high resolution, and color depth allow for incredible graphics suitable for multimedia and graphic intensive applications.

Extended Capabilities Port. A parallel-port standard for PCs that supports bidirectional communication between the PC and attached devices (such as a printer). ECP is about 10 times faster than the older Centronics standard. Another modern parallel port for PCs that offers similar performance is the EPP (Enhanced Parallel Port).

EDO memory

Extended Data Out memory. A faster type of asynchronous computer memory that holds its last-requested data in a cache after releasing it. EDO memory is designed for use with the Intel Pentium processors.
