Page 15

Technical Information 1-3

PCI Local Bus

The 32-bit industry-standard PCI bus is a highly-integrated input/output (I/O) interface that offers the highest performance local bus available for the Pentium II processor. The PCI bus supports burst modes that send large chunks of data across the bus, allowing fast displays of high-resolution images.

The high-bandwidth PCI local bus eliminates data bottlenecks found in traditional systems, maintains maximum performance at high clock speeds, and provides a clear upgrade path to future technologies.

The PCI bus contains two embedded PCI devices: the PCI local bus IDE interface and the PCI video/graphics controller. The PCI bus also contains a connector for attaching the bus expansion board.

Expansion Bus

The expansion bus contains one ISA slot, three PCI slots, one PCI/ISA slot, and one AGP video slot. The PCI ISA IDE Xccelerator chip (PIIX4E) provides the logic that enables the ISA bus functions. With 24-bit memory addressing, a 16-bit data path, and an eight MHz

clock, the ISA bus is designed to support all peripherals compatible with the IBM AT standard. For PCI functions, the Xcelerator chip provides 32-bit memory addressing, 32-bit data path, and a 33-MHz clock speed.



BIOS

The BIOS (Basic Input Output System) is stored in the Intel 28F002 Flash EPROM. The Flash EPROM is reprogrammable and allows fast, economical BIOS upgrades.

1-4 Technical Information

Plug and Play Support

The system comes with Plug and Play BIOS technology. Plug and Play eliminates complicated setup procedures for installing Plug and Play expansion boards.

To add a Plug and Play expansion board, simply power off the system, install the board, and power on the system. There are no jumpers to set and no system resource conflicts to resolve. Plug and Play automatically configures the board for the system. The system also supports non-Plug and Play boards.

Plug and Play is controlled by the Plug and Play BIOS and the system’s operating system. The Plug and Play BIOS is stored in the Intel 28F002 Flash EPROM on the system board.

The Plug and Play BIOS adds several steps to the POST process. During POST, the Plug and Play evaluates the configuration of installed boards and assigns available system resources to the devices. On completion of Plug and Play POST, the operating system checks to see if there are any additional resources required, then assigns available resources to the devices.

CMOS Memory/Real-Time Clock Battery

The 82371EB PCI ISA IDE Xcelerator (PIIX4E) on the system board stores system information in non-volatile CMOS memory. The chip also contains the system’s real-time clock. Both are maintained by a 3-volt coin cell lithium battery on the system board. The battery is replaceable.

DMA/IRQ Settings

The system automatically configures interrupts requests (IRQ), direct memory access (DMA) channels, and other parameters when adding PCI boards with minimal user intervention.

Table 1-3 and Table 1-4 list system IRQ and DMA default settings.

1-6 Technical Information

IDE Ports

The system board provides two fast IDE ports: primary channel and secondary channels. Each port supports two devices for a total of four IDE devices. The system board allows

the connection of an IDE CD-ROM drive for system configuration flexibility without the addition of a controller.

The IDE ports feature an enhanced IDE interface which supports up to 10 MB per second 32-bit wide data transfers on the high-performance PCI local bus. The standard hard disk and Zip drive (in some systems) are connected to the primary channel. The CD-ROM drive is attached to the secondary channel.

I/O Ports

The system board features an enhanced parallel port, two buffered high-speed serial ports, and two Universal Serial Bus (USB) ports.

The enhanced parallel port supports Enhanced Capabilities Port (ECP) and Enhanced Parallel Port (EPP) modes for devices that require ECP or EPP protocols. These protocols allow high-speed bi-directional transfer over a parallel port and increase parallel port functionality by supporting more devices.

The two buffered high-speed serial ports use a fast 16C550 UART which supports transfer rates up to 115.2 kilobits (Kb) per second. These ports allow the installation of high-speed serial devices for faster data transfer rates.

The two USB ports allow additional new plug and play serial devices without removing the system cover. Simply plug the USB device into the port. The speed varies between 12 megabits per second (Mbps) for printers and 1.5 Mbps for mice and keyboards. Up to 127 USB devices can be connected to the computer.

The combination of the enhanced parallel port, buffered serial ports, and USB ports ensure optimum performance for future peripheral devices and operating systems.

Sound System

The system board features the Crystal Semiconductor CS4236B audio codec and CS4611 PCI audio accelerator. The CS4236B integrates an internal FM music synthesizer and joystick logic. The chip also provides the following features.



Advanced power management



Symmetrical mixer



Support for DirectSound

™



Full-duplex audio



Sound Blaster®, Sound Blaster Pro, and Windows Sound System™ compatibility

Page 19

Technical Information 1-7

Each board provides receive transfer rates of 56 Kbps (kilobytes per second) for data and 14.4 Kbps for fax.

DISKETTE DRIVE

The system comes standard with a 1.44-MB high-density diskette drive preinstalled in the 3 1/2-inch accessible device slot (drive A). The drive is connected to the system board via a two-connector cable.

HARD DRIVE

The system supports up to three IDE hard drives, the standard hard drive, and two optional hard drives (if a Zip drive does not come standard with the system).

CD-ROM/DVD DRIVE

The drive can be used to load programs from a CD or it can be used to play audio CDs. The drive operates at different speeds depending on whether the CD contains music or data. The drive is fully compatible with Kodak Multisession Photo CDs™ and standard CDs.

The drive is connected to the secondary IDE/PCI port on the system board.

ZIP DRIVE

Some systems come with the Iomega® Zip 100 ATA drive. The Zip drive provides removable 100-MB data disks and has a data transfer rate up to 1.4 MB per second.

POWER SUPPLY

The 235-watt power supply is mounted inside the system unit. It supplies power to the system board, option boards, diskette drives, hard drives, keyboard, and mouse. A fan inside the power supply provides system ventilation. The power supply has several cables for attaching to the various devices requiring power.

Page 20

1-8 Technical Information

POWER MANAGEMENT

The Advanced Power Management (APM) program, located on the 82371EB PCI ISA IDE Xcelerator (PIIX4E) chip, reduces system power consumption when there is no activity detected from the keyboard, mouse, diskette drive, CD-ROM/DVD drive, or hard disk drive after a predefined period of time. As soon as activity is detected, the system resumes where it left off.
