I/O Ports

The IDE ports feature an enhanced IDE interface which supports up to 16.7 MB per second 32-bit wide data tr ansfers on t he high-performance PCI local bus. The standard hard drive and Zip® drive (in some systems) are connected to t he primary channel. The CD-ROM drive is att ached t o t he seco ndar y channel.

The system board features an enhanced para llel port , one buffered high-speed serial port, 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 one buffered high-speed serial port uses a fast 16C550 UART which supports transfer rates up to 115.2 kilobits (Kb) per second. This port allows the installation of high-speed serial devices for faster dat a transfer r ates.

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 ser ia l ports, and USB ports ensure optimum performance for future peripheral devices and operating systems.

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 secondar y IDE/PCI port on the syste m board.

Zip Drive

Some systems come with the Iome ga® 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, d iskette 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 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 drive after a predefined period of time. As soon as activity is detected, the system resumes where it left off.

In the CMOS Setup utility, a n inactivity timer is ava ilabl e for s e tting the length of time before the system enters a low-power mode.
