Chapter 3 BIOS Setup This chapter describes the different settings available in the Award BIOS that comes with the M3 CPU card. The topics covered in this chapter are as follows: BIOS Introduction....................................................... 35 Main Menu ................................................................... 38 Standard CMOS Setup ............................................... 40 Advanced BIOS Features........................................... 45 Advanced Chipset Features .........
BIOS Introduction This Chapter discusses Award™ Setup program built into the M3 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. The AwardBIOS™ installed in M3 SBC is a custom version of an industry standard BIOS. This means that it supports Intel PentiumIV in a standard IBM-AT compatible input/output system.
do not press the keys at the correct time and the system does not boot, an error message will be displayed and you will again be asked to... PRESS F1 TO CONTINUE, DEL TO ENTER SETUP Using Setup In general, you use the arrow keys to highlight items, press to select, use the PageUp and PageDown keys to change entries, press for help and press 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 or the F1 key again. In Case of Problems If, after making and saving system changes with Setup, you discover that your computer no longer is able to boot, the AwardBIOS™ supports an override to the CMOS settings which resets your system to its defaults. The best advice is to only alter settings that you thoroughly understand.
Main Menu Once you enter the AwardBIOS™ 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 to accept and enter the sub-menu.
Advanced Chipset Features Use this menu to change the values in the chipset registers and optimize your system's performance. Integrated Peripherals Use this menu to specify your settings for integrated peripherals. Power Management Setup Use this menu to specify your settings for power management. PnP / PCI Configuration Use this menu to set up the PnP/PCI configuration. PC Health Status Use this menu to display the CPU temperature, FAN speed and voltages.
Standard CMOS Setup The items in Standard CMOS Setup Menu are divided into 10 categories. Each category includes no, one or more than one setup items. Use the arrow keys to highlight the item and then use the or keys to select the value you want in each item.

In effect, the system remains alert for anything which occurs to a device which is configured as Enabled, even when the system is in a Suspend down mode.
PnP/PCI Configuration Setup This section describes configuring the PCI bus system. PCI, or Personal Computer Interconnect, is a system which allows I/O devices to operate at speeds nearing the speed the CPU itself uses when communicating with its own special components. This section covers some very technical items and it is strongly recommended that only experienced users should make any changes to the default settings.
Resources controlled by BIOS can automatically configure all the boot and Plug and Play compatible devices. If you choose Auto, you cannot select IRQ DMA and memory base address fields, since BIOS automatically assigns them. The choice: Auto (ESCD), Manual. IRQ Resources When resources are controlled manually, assign each system interrupt a type, depending on the type of device using the interrupt. This item allows you to determine the IRQ assigned to the ISA bus and is not available to any PCI slot.
PC Health Status This section helps you to get more information about your system including CPU temperature, FAN speed and voltages. It is recommended that you contact with your motherboard supplier to get proper value about your setting of the CPU temperature.
CPU FAN Speed Shows CPU FAN speed. System FAN Speed Shows System FAN speed. Vcore/1.5V/3.3V/5V/12V/-12V/-5V/VBAT/5VSB Voltages Shows Power rails voltage. CPU FAN The choice: Disabled, Enabled. SYSTEM FAN The choice: Disabled, Enabled.

Load Fail-Safe Defaults When you press on this item you get a confirmation dialog box with a message similar to: Load Fail-Safe Defaults (Y/N) ? N Pressing ‘Y’ loads the BIOS default values for the most stable, minimal-performance system operations.
Supervisor/User Password Setting You can set either supervisor or user password, or both of then. The differences between are: supervisor password : can enter and change the options of the setup menus. user password : just can only enter but do not have the right to change the options of the setup menus. When you select this function, the following message will appear at the center of the screen to assist you in creating a password.
Exit Selecting Save & Exit Setup Pressing on this item asks for confirmation: Save to CMOS and EXIT (Y/N)? Y Pressing “Y” stores the selections made in the menus in CMOS – a special section of memory that stays on after you turn your system off. The next time you boot your computer, the BIOS configures your system according to the Setup selections stored in CMOS. After saving the values the system is restarted again.
CHAPTER 4 Appendix I/O Port Address Map ................................................. 72 Interrupt Request Lines(IRQ)..................................... 73 POST Beep ..................................................................
A. I/O Port Address Map Each peripheral device in the system is assigned a set of I/O port addresses which also becomes the identity of the device. There are a total of 1K port address space available. The following table lists the I/O port addresses used on the Industrial CPU Card.
B. Interrupt Request Lines (IRQ) There are a total of 15 IRQ lines available on the Industrial CPU Card. Peripheral devices use interrupt request lines to notify CPU for the service required. The following table shows the IRQ used by the devices on the Industrial CPU Card.
C. POST Beep Currently there are two kinds of beep codes in BIOS. This code indicates that a video error has occurred and the BIOS cannot initialize the video screen to display any additional information. This beep code consists of a single long beep followed by two short beeps. The other code indicates that your DRAM error has occurred. This beep code consists of a single long beep repeatedly.
