Chapter 4 AMI BIOS Setup Getting Start This manual discusses AMI's Setup program built into the ROM BIOS. The Setup program allows users to modify the basic system configuration. This special information is then stored in battery-backed RAM so that it retains the Setup information when the power is turned off.
Using Setup In general, you use the arrow keys to highlight items, press <Enter> to select, use the PageUp and PageDown keys to change entries, press <F1> for help and press <Esc> to quit.The following table provides more detail about how to navigate in the Setup program using the keyboard.
Getting Help Press F1 to pop up a small help window that describes the appropriate keys to use and the possible selections for the highlighted item. To exit the Help Window press <Esc> or the F1 key again. If, after making and saving system changes with Setup, you discover that your computer no longer is able to boot, the AMI BIOS supports an override to the CMOS settings which resets your system to its defaults.
Main Menu Once you enter the AMIBIOS™ CMOS Setup Utility, the Main Menu will appear on the screen. The Main Menu allows you to select from several setup functions and two exit choices. Use the arrow keys to select among the items and press <Enter>...
When Disabled, SMI will not be initialized, and complete power management functionality is removed until this option is set to Enabled. PCI / Plug and Play Setup This entry appears if your system supports PnP / PCI. Peripheral Setup Use this menu to specify your settings for integrated peripherals.

This chapter discusses the Setup program built into the BIOS. which allows users to configure the system. This configuration is then stored in battery-backed CMOS RAM so that Setup information is retained whilst the power is off.
Appendix A. Watchdog Timer The Watchdog Timer is a device to ensure that standalone systems can always recover from abnormal conditions that cause the system to crash. These conditions may result from an external EMI or a software bug. When the system stops working, hardware on the board will perform hardware reset (cold boot) to bring the system back to a known state.

Appendix C. How to use Wake-Up Function PCISA-6755 provides two kinds of Wake-up function. This page describes how to use Modem Wake-Up and LAN Wake-Up functions. Wake-Up function only works with ATX power supply. Wake-Up On Modem(Ring): You must set the option Wake-Up On LAN/Ring of CMOS SETUP to be enabled.
Appendix D. Digital I/O One characteristic of digital circuit is its fast response to high or low signal. This kind of response is highly needed for harsh and critical industrial operating environment. That’s why we design 4-bit digital inputs and 4-bit digital outputs on the PCISA-6755. There are two kinds of signals (Input and Output) used by the Digital I/O function.
