3-3-1. Watchdog Timers Setting The watchdog timer is a circuit that may be used from your program software to detect system crashes or hang-ups. Whenever the watchdog timer is enabled, the LED will blink to indicate that the timer is counting. The watchdog timer is automatically disabled after reset. Once you have enabled the watchdog timer, your program must trigger the watchdog timer every time before it times out.
3-3-3. Watchdog Timer Trigger After you enable the watchdog timer, your program must write the same factor as enabling to the watchdog register at least once every time-out period to its previous setting. You can change the time-out period by writing another timer factor to the watchdog register at any time, and you must trigger the watchdog before the new time-out period in the next trigger. Below is a Turbo C++ program that demonstrates how to trigger the watchdog timer: #include “studio.

4-1. BIOS SETUP OVERVIEW The BIOS is a program used to initialize and set up the I/O system of the computer, which includes the PCI bus and connected devices such as the video display, diskette drive, and the keyboard. The BIOS provides a menu-based interface to the console subsystem. The console subsystem contains special software, called firmware that interacts directly with the hardware components and facilitates interaction between the system hardware and the operating system.
4-2. STANDARD CMOS SETUP The option allows you to record some basic system hardware configurations and set the system clock and error handling. If the CPU board is already installed in a working system, you will not need to select this option anymore. AMIBIOS SETUP - STANDARD CMOS SETUP (C) 1999 American Megatrends, Inc. All Rights Reserved Date (mm/dd/yyyy): Tue Jun 02,1998 Time (hh/mm/ss): 13:39:30 Floppy Drive A: Floppy Drive B: 640KB 63MB 1.
Installation of new operating systems requires that you disable this to prevent write errors. 4-3. ADVANCED CMOS SETUP The option consists of configuration entries that allow you to improve your system performance, or let you set up some system features according to your preference. Some entries here are required by the CPU board’s design to remain in their default settings. AMBIOS SETUP – ADVANCED CMOS SETUP (C) 1999 American Mega trends, Inc.
Floppy Access Control This option determines the floppy access method, which can be either read only or normal (read/write). When set to read only, the data in the floppy is allowed to read instead of being written.” Normal” allows the floppy to be read or written. HDD Access Control This option determines the hard disk access method, which can be either read only or normal (read/write). When set to read only, the data in the hard disk is allowed to read instead of being written.
Wait for ‘F1’ If Error AMIBIOS POST error messages are followed by: Press to continue If this option is set to Disabled, the AMIBIOS does not wait for you to press the key after an error message. Hit ‘DEL’ Message Display Set this option to Disabled to prevent the following message: Hit ‘DEL’ if you want to run setup It will prevent the message from appearing on the first BIOS screen when the computer boots.
Shadow These options control the location of the contents of the 16KB of ROM beginning at the specified memory location. If no adapter ROM is using the named ROM area, this area is made available to the local bus. The settings are: SETTING Disabled Enabled Cached ~ Page 32 ~ DESCRIPTION The video ROM is not mapped to RAM. The contents of the video ROM cannot be read from or written to cache memory.
4-4. ADVANCED CHIPSET SETUP This option controls the configuration of the board’s chipset. Control keys for this screen are the same as for the previous screen. AMBIOS SETUP – ADVANCED CHIPSET SETUP (C) 1999 American Mega trends, Inc.
The item is to set up CPU to demand ISA Bus 8 bit how much it takes to recovery. 16 bit I/O Recovery Time: The item is to set up CPU to demand ISA Bus 16 bit how much it takes to recovery. Memory Hole at 15-16 MB This option specifies the range 15MB to 16MB in memory that cannot be addressed on the ISA bus. USB Function This option can enable or disable USB function USB Keyboard/Mouse Legacy Support These options are used to the USB function and it’s only useful in the DOS mode.
4-5. POWER MANAGEMENT This section is used to configure the power management features. This option allows you to reduce power consumption. This feature turns off the video display and shuts down the hard disk after a period of inactivity. AMBIOS SETUP – POWER MANAGEMNT SETUP (C) 1999 American Mega trends, Inc.
Suspend Time Out (minute) These options specify the length of the period of system inactivity when the computer is already in Standby mode before the computer is placed on Suspend mode. In Suspend mode, nearly all power use is curtailed. Throttle Slow Clock Ratio This item is to set up the Operating Frequency of system clock in power saving mode, to set a suitable clock frequency ratio which between standard CPU clock and CPU clock in power saving mode when the system is in suspend mode.
4-6. PCI/PLUG AND PLAY This section is used to configure PCI / Plug and Play features. The option configures the PCI bus slots. All PCI bus slots on the system use INTA#, thus all installed PCI cards must be set to this value. AMBIOS SETUP – PCI/PLUG AND PLAY SETUP (C) 1999 American Mega trends, Inc.
On board PCI LAN Controller This option is to activate the PNP (Plug & Play) function of LAN. PCI Latency Timer (PCI Clocks) This option sets latency of all PCI devices on the PCI bus. The settings are in units equal to PCI clocks. Primary Graphic Adapter This option is set to use PCI bus or AGP. The AGP mode will get system a faster processing speed. PCI VGA Palette Snoop This item is for BIOS to snoop the appearance of VGA palette, and modify it when necessary.
4-7. PERIPHERAL SETUP This section is used to configure the peripheral features. AMBIOS SETUP – PERIPHERAL SETUP (C) 1999 American Mega trends, Inc.
4-8. AUTO-DETECT HARD DISKS This option detects the parameters of an IDE hard disk drive, and automatically enters them into the Standard CMOS Setup screen. 4-9. PASSWORD SETTING This BIOS Setup has an optional password feature. The system can be configured so that all users must enter a password every time the system boots or when BIOS Setup is executed. The user can set either a Supervisor password or a User password. 4-10.
4-12-2. Auto Configurations with Fail Safe Setting The user can load the Fail-Safe BIOS Setup option settings by selecting the Fail-Safe item from the Default section of the BIOS Setup main menu. The Fail-Safe settings provide far from optimal system performance, but are the most stable settings. Use this option as a diagnostic aid if the system is behaving erratically. Load failsafe settings (Y/N)? 4-13. BIOS EXIT This section is used to exit the BIOS main menu.
4-14. BIOS UPDATE The BIOS program instructions are contained within computer chips called FLASH ROMs that are located on your system board. The chips can be electronically reprogrammed, allowing you to upgrade your BIOS firmware without removing and installing chips. The AR-B1682 provides the FLASH BIOS update function for you to easily to update to a newer BIOS version. Please follow these operating steps to update to new BIOS: Step 1: Turn on your system and don’t detect the CONFIG.SYS and AUTOEXEC.

APPENDIX C TROUBLE SHOOTING TROUBLE SHOOTING FOR ERROR MESSAGES The following information will present the resolution of trouble encountered as well as the error messages. Adjust the system following the messages below and make sure all the components & connectors are in proper position and firmly attached. If the error still remains, contact with your distributor for maintenance. POST BEEP: There are two kinds of beep codes in BIOS.
MEMORY ADDRESS ERROR: While the memory address error revealed, trace the error location with the memory map in system and replace the bad memory chips. MEMORY SIZE HAS CHANGED: Memory has been added or removed since the last boot. In EISA mode, re-configure the memory configuration by using Configuration Utility. While in ISA mode, enter Setup and enter the new memory size in the memory fields. MEMORY VERIFYING ERROR: It indicates an error verifying value has been written to memory.
