    Hardware Installation Pentium II 500 MHz Pentium II 550 MHz Pentium II 600 MHz Pentium II 650 MHz The CPU is a sensitive electric component and it can be easily damaged by static electricity, so users must keep it away from metal surface when the CPU is installed onto mainboard.
  • Page 23: Ide & Atapi Device Installation

    6BMM 3.10. IDE & ATAPI DEVICE INSTALLATION There are two-Enhanced PCI IDE ports (IDE1, IDE2) on board, which following ATAPI standard SPEC. Any one IDE port can connected to two ATAPI devices (IDE Hard Disk, CD-ROM & Tape Driver), so total four ATAPI devices can exist in a system.
  • Page 24: Entering Setup

    BIOS Configuration 4.BIOS CONFIGURATION Award's BIOS ROM has a built-in Setup program that allows users to modify the basic system configuration. This type of information is stored in battery-backed CMOS SRAM so that it retains the Setup information when the power is turned off.
