The factor of the watchdog timer time-out constant is approximately 1 MINUTES. The period for the watchdog timer time-out is between 1 to FF timer factors. If you want to reset your system when watchdog times out, the following table listed the relation of timer factors between time-out period. The formula of Time-Out Period is 30+60x(Time Factor -1). For example, if the time factor is 10. The Time-out period is calculated as 30+60x(10-1)= 570.
3-4-4. Watchdog Timer Disabled To disable the watchdog timer, simply write a 00H to the watchdog register. #include “ stadio.H” #include “WATCHDOG.

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.

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. AMIBIOS SETUP - ADVANCED CMOS SETUP (C) 1999 American Megatrends, Inc.
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 be read instead of being written.” Normal” allows the floppy to be read or written. Available options: Disabled, Enabled S.M.A.R.T for hard Disks S.M.A.R.T is abbreviation of Self-Monitoring Analysis and Reporting Technology .It is reliable and precautious techology.
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. Internal Cache This option specifies the caching algorithm used for the L1 internal cache memory. The settings are: Setting Disabled WriteBack WriteThru Description Neither L1 internal cache memory on the CPU or L2 secondary cache memory is enabled. Use the write-back caching algorithm.
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. AMIBIOS SETUP - ADVANCED CHIPSET SETUP (C) 1999 American Megatrends, Inc.
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. ATX Power Supply Controller If the ATX Power Supply Controller function is , the system will get more functions such as shutting down the power by using software .
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. MIBIOS SETUP - Power Management Setup (C) 1998 American Megatrends, 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. AMIBIOS SETUP - PCI/PLUG AND PLAY SETUP (C) 1998 American Megatrends, Inc.
PCI VGA Palette Snoop This item is for BIOS to snoop the appearance of VGA palette, and modify it when necessary. PCI IDE BusMaster When Enabled this option specifies that the IDE controller on the PCI local bus has bus mastering capability. PCI Slot1/2/3/4 IRQ Priority The parameters of this item will set a interrupt signal to the PCI device fixed in the 1-4 PCI slot by priority. DMA & IRQ These options specify the bus that the named IRQs/DMAs lines are used on.
4-7. PERIPHERAL SETUP This section is used to configure the peripheral features. AMIBIOS SETUP - PCI/PLUG AND PLAY SETUP (C) 1998 American Megatrends, Inc.
OnBoard IDE This option is to set up the operating mode of IDE controller. If the main board offer the enhanced I/O port, the choice should be . Reset, Power, Sleep Button These options are to activate the Reset, Power, and Sleep function in the ATX Keyboard. 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.
these items to quickly set system configuration parameters, you can choose a group of settings that have a better chance of working when the system is havi ng configuration related problems. 4-12-1. Auto Configuration with Optimal Setting The user can load the optimal default settings for the BIOS. The Optimal default settings are best-case values that should optimize system performance. If CMOS RAM is corrupted, the optimal settings are loaded automatically. Load high performance setting (Y/N) ? 4-12-2.
Step 1: Turn on your system and don’t detect the CONFIG.SYS and AUTOEXEC.BAT files. Step 2: Insert the FLASH BIOS diskette into the floppy disk drive. Step 3: In the MS-DOS mode, you can type the FLASH812 program. A:\>FLASH812 Step 4: Press [ALT+F], The box will show the following message, this message will be highlighted.

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.
