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 U6520222D 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.

Technical Information 1-5

CMOS Memory/Real-Time Clock Battery

The 430TX PCI ISA IDE Xcelerator (PIIX4) 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.

IDE Ports

The system board provides two IDE ports:



a fast IDE port (the primary channel) a standard IDE port (the secondary channel).



Each port supports two devices for a total of four IDE devices. The system board allows the connection of an IDE CD-ROM reader for system configuration flexibility without the addition of a controller.

The fast IDE port features an enhanced IDE interface which supports up to 10 MB per second 32-bit wide data transfers on the high-performance PCI local bus. (Standard IDE supports 2 MB to 3 MB per second on the ISA bus.) The standard hard disk and Zip drive (in some systems) are connected to the fast IDE port (primary channel) for high performance. The CD-ROM reader is attached to the standard IDE port (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 fast 16550 UARTs which support transfer rates up to 19.2 kilobytes (KB) per second. These ports allow the installation of high-speed serial devices for faster data transfer rates.

Technical Information 1-7

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 Yamaha OPL® YMF715 audio chip. It integrates a 16-bit audio codec, OPL3 FM synthesis and DAC, 3D enhanced stereo controller, and an interface for MPU401 and a joystick. The chip also provides the following features.

U.S. ROBOTICS SPORTSTER FAX/MODEM BOARD

The fax/modem board (in some systems) contains fax and modem capabilities. The board provides modem, fax, full-duplex speakerphone, and voicemail capabilities. The board provides 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 pre-installed 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 DISK 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). The standard hard drive is either a 3.2-GB, 4.3-GB, or 7-GB drive.

1-8 Technical Information

CD-ROM READER

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

The reader 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 200-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.

POWER MANAGEMENT

The Advanced Power Management (APM) program, located on the 430TX System Controller (MTXC) chip, reduces system power consumption when there is no activity detected from the keyboard, mouse, diskette drive, CD-ROM reader, or hard disk drive after a pre-defined period of time. As soon as activity is detected, the system resumes where it left off.

There are four levels of reduced power consumption, which may be selected in the CMOS Setup utility. The four levels are Disabled, Minimum Power Savings, Customized, and Maximum Power Savings. Each setting provides a timer in which the system activates the Standby, Suspend, and Fixed Disk power-saving schemes.
