2. Primary/Secondary IDE connectors (40-1 pin IDE1/IDE2) This connector supports the provided UltraDMA/100/66 IDE hard disk ribbon cable. Connect the cables blue connector to the primary (recommended) or secondary IDE connector, then connect the gray connector to the UltraDMA/100/66 slave device (hard disk drive) and the black connector to the UltraDMA/100/66 master device. It is recommended that you connect non-UltraDMA/100/66 devices to the secondary IDE connector. If you install two hard disks, you must configure the second drive as a slave device by setting its jumper accordingly. Refer to the hard disk documentation for the jumper settings. BIOS supports specific device bootup. If you have more than two UltraDMA/100/66 devices, purchase another UltraDMA/100/66 cable. You may configure two hard disks to be both master devices with two ribbon cables one for the primary IDE connector and another for the secondary IDE connector.
1. Pin 20 on each IDE connector is removed to match the covered hole on the UltraDMA cable connector. This prevents incorrect orientation when you connect the cables. 2. The hole near the blue connector on the UltraDMA/100/66 cable is intentional.

Glossary

This part lists the technical terms that you may encounter when reading this document.
This glossary also includes some terms that are not found in this document but might be of help to you when operating, upgrading, or reconfiguring your computer.
AC97 (Audio Codec '97). AC '97 is the next step in enabling PCs with audio quality comparable to consumer electronics devices. The specification defines new cost-effective options to help integrate the components necessary to support next-generation auto-intensive PC applications such as DVD, 3-D multiplayer gaming and interactive music. The specification also defines new extensions supporting modem and docking to help both desktop and mobile manufacturers adopt these new technologies more quickly and cost-effectively. This specification uses software emulation to compete with the PCI SoundBlaster specification. ACPI (Advanced Configuration and Power Interface). The ACPI specification defines a cross-platform interface designed to support many operating systems. ACPI defines a flexible and abstract hardware interface that provides a standard way to integrate power management features in a PC system, including hardware, operating system and application software. This enables the system to automatically turn ON and OFF peripherals such as CD-ROMs, network cards, hard disk drives, and printers, as well as consumer devices connected to the PC such as VCRs, TVs, phones, and stereos. With this technology, peripherals are also able to activate the PC. For example, inserting a tape into a VCR can turn on the PC, which could then activate a large-screen TV and high-fidelity sound system. AGP (Accelerated Graphics Port). An interface specification that enables high-performance 3D graphics on mainstream PCs. AGP was designed to offer the necessary bandwidth and latency to perform texture mapping directly from system memory.

Bus PCI AGP 1X AGP 2X AGP 4X Bus Frequency 33MHz 66MHz 66MHz 66MHz Bandwidth 33MHz 66MHz 133MHz 266MHz Data Transfer Rate 133MByte/sec 266MByte/sec 512MByte/sec 1024MByte/sec
Backup. A copy of a file, directory, or volume on a separate storage device from the original. This copy is for the purpose of data retrieval in case the original is accidentally erased, damaged, or destroyed.
BIOS (Basic Input/Output System). BIOS is a set of routines that control how the computer transfers data between computer components, such as memory, disks, and the display adapter. The BIOS instructions are built into the computers read-only memory. BIOS parameters are configurable through the BIOS Setup program. You can update the BIOS using the AFLASH utility by copying a new BIOS file into the EEPROM. Bit (Binary Digit). Represents the smallest unit of data used by the computer. A bit can have one of two values: 0 or 1. Boot. Boot means to start the computer operating system by loading it into system memory. When the manual instructs you to boot your system (or computer), it means to turn ON your computer. Reboot means to restart your computer. When using Windows 95 or later, selecting Restart from Start | Shut Down. will reboot your computer. Bus Master IDE. PIO (Programmable I/O) IDE requires that the CPU be involved in IDE access and waiting for mechanical events. Bus master IDE transfers data to/from the memory without interrupting the CPU. Bus master IDE driver and bus master IDE hard disk drives are required to support bus master IDE mode. Byte (Binary Term). One byte is a group of eight contiguous bits. A byte is used to represent a single alphanumeric character, punctuation mark, or other symbol. Cache Memory. A type of RAM that allows a faster from the CPU than a regular RAM. The cache memory eliminates the CPU wait state. When the CPU reads data from the main memory, a copy of this data is stored in the cache memory. The next time the same address, the data is transferred from the cache memory instead of from the main memory. CODEC (Compressor/Decompressor). A software component that translates video or audio between its uncompressed form and the compressed form in which it is stored. COM Port. A connector with the accompanying circuitry that supports serial devices such as printers, mice, modems, and infrared modules. Each COM port is configured to use a different IRQ and address assignment. COM port is short for communication port, and is also called a serial port. CPU (Central Processing Unit). The CPU, also called Processor, actually functions as the brain of the computer. It interprets and executes program commands and processes data stored in the system memory.

Appendix C: Glossary

Device Driver. A software routine that links a peripheral device to the operating system. It acts as a translator between the device and the applications that use it. Each device has its own set of specialized commands known only to its driver while the applications access devices using high-level generic commands. The driver translates these commands into the commands required by the devices. DOS (Disk Operating System). A software that organizes how a computer reads, writes, and communicate to the disks and various input/ output devices (such as keyboards, screens, serial and parallel ports, printers, modems, etc.) connected to it.
