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).

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.

POWER MANAGEMENT

The Advanced Power Management (APM) program, located on the 82371AB PCI ISA
IDE Xcelerator (PIIX4) chip, reduces system power consumption when there is no activity
detected from the keyboard, mouse, diskette drive, CD-ROM drive, or hard disk 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, an inactivity timer is available for setting the length of time
before the sytem enter a low-power mode.
