identifies the drive bays. Use this illustration to locate interior features and
components discussed later in this guide.
Figure 7-3. Inside the System
The system board holds the system's control circuitry and other electronic
components. Several hardware options such as the microprocessor and memory are
installed directly on the system board.
The expansion card riser board accommodates one full-length peripheral component
interconnect (PCI) expansion card and one low-profile PCI card (occupied by the video
controller).
The peripheral bays provide space for an integrated 3.5-inch diskette drive and
CD-ROM drive, and two 1-inch hard-disk drives. For more information, see Chapter 9,
“
Installing Drives”.
The power cables leading from the power supply distribute power to the system
board and all installed drives.
For drives such as the diskette drive and the CD-ROM drive, an interface connector
connects each drive to the system board.
