BIOS Setup
Introduction
T he purpose of this manual is to describe the settings in the AMI BIOS Setup program on this motherboard. The Setup program allows users to modify the basic system configuration and save these settings to CMOS RAM. T he power of CMOS RAM is supplied by a battery so that it retains the Setup information when the power is turned off. Basic Input-Output System (BIOS) determines what a computer can do without accessing programs from a disk. [. . . ] Options: Auto (Default) / Floppy / Forced FDD / Hard Disk / CDROM

3 PCIPnP Menu
T his section describes con figuring the PCI bus system. PCI, or Personal Computer Interconn ect, is a system which allows I/O devices to operate at speeds nearing the speed o f the CPU itself uses when communicating with its own special components.
Notice
Beware of that setting inappropriate values in items of this menu may cause system to malfunction.
