0.6 STATIC ELECTRICITY PRECAUTIONS

Before removing the board from its anti-static bag, read this section about static electricity precautions. Static
electricity is a constant danger to computer systems. The charge that can build up in your body may be more than
sufficient to damage integrated circuits on any PC board. It is, therefore, important to observe basic precautions
whenever you use or handle computer components. Although areas with humid climates are much less prone to
static build-up, it is always best to safeguard against accidents that may result in expensive repairs. The following
measures should be sufficient to protect your equipment from static discharge:
Touch a grounded metal object to discharge the static electricity in your body (or ideally, wear a grounded wrist
strap).
When unpacking and handling the board or other system components, place all materials on an anti-static surface.
Be careful not to touch the components on the board, especially the “golden finger” connectors on the bottom of the
board.

4. WATCHDOG TIMER

This section describes the use of Watchdog Timer. AR-B1665 is equip ped with a programmable time-out period
watchdog timer that enable user to reset the system after a time out occur. Users can use simple program to enable
the watchdog timer, and program the timer in range of seconds or minutes, with maximum 255 seconds/minutes.
Once you enable the watchdog timer, the program will start the count down and when counting down to zero the
system will generate a reset signal to reset the system.

4.1 WATCHDOG TIMER SETTING

The watchdog timer is a circuit that maybe be used from your program software to detect crash or hang up.

The Watchdog timer is automatically disabled after reset. Once you enabled the watchdog timer, your program
should trigger the watchdog timer every time before it times out. After you trigger the watchdog timer, the timer will
be set to zero and start to count again. If your program fails to trigger the watchdog timer before times out, it will
generate a reset pulse to reset the system .

Please refer to the following table in order to properly program Watchdog function

Users could test watchdog function under ‘Debug’ program as follows:

5. BIOS CONSOLE

This chapter describes the AR-B1665 BIOS menu displays and explains how to perform common tasks needed to
get up and running, and presents detailed explanations of the eleme nts found in each of the BIOS menus. The
following topics are covered:

 Main
 Advanced
 Peripherals
 Boot
 PC Health
 Exit

5.1 MAIN

The BIOS is a program used to initialize and set up the I/O system of the computer, which includes the ISA 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.
The BIOS default values ensure that the system will function at its normal capability. In the worst situation the user
may have corrupted the original settings set by the manufacturer.
After the computer is turned on, the BIOS will perform diagnostics on the system and display the size of the
memory that is being tested. Press the [Del] key to enter the BIOS Setup program, and then the main menu will
show on the screen.
The BIOS Setup main menu includes some options. Use the [Up/Down] arrow key to highlight the option that you
wish to modify, and then press the [Enter] key to select the option and configure the functions.

Main Menu

The <Main> option allows you to record some basic system hard ware configuration and s et 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.

Date & Time Setup

Highlight the <Date> field and then press the [Page Up] /[Page Down] or [+]/[-] keys to set the current date. Follow
the month, day and year format.
Highlight the <Time> field and then press the [Page Up] /[Page Down] or [+]/[-] keys to set the current date. Follow
the hour, minute and second format.
The user can bypass the date and time prompts by creating an AUTOEXEC.BAT file. For information on how to
create this file, please refer to the MS-DOS manual.

Hard Disk Setup

The BIOS supports various types for user settings, The BIOS supports <Pri Master>, <Pri Slave>, <Sec Master>
and <Sec Slave> so the user can install up to two hard disks. For the master and slave jumpers, please refer to
the hard disk’s installation descriptions and the hard disk jumper settings in section three of this manual.

Floppy Setup

The <Main> option records the types of floppy disk drives installed in the system.
To enter the configuration value for a particular drive, highlight its corresponding field and then select the drive type
using the left-or right-arrow key.

5.2 ADV ANCED

The <Advanced > 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.

Advanced

Quick Post

This category speeds up Power On Self Test (POST) after you power on the computer. If it is set to Enabled,
BIOS will shorten or skip some check items during POST.

These options determine where the system looks first for an operating system.

20

AR-B1665 User’s Guide

PS/2 Mouse Function

The setting of Enabled allows the system to detect a PS/2 mouse on boot up. If detected, IRQ12 will be used for
the PS/2 mouse. IRQ 12 will be reserved for expansion cards if a PS/2 mouse is not detected. Disabled will
reserve IRQ12 for expansion cards and therefore the PS/2 mouse will not function.

Onboard FDC Controller

Select Enabled if your system has a floppy disk controller (FDC) installed on the system board and you wish to use it.
If you install add-on FDC or the system has no floppy drive, select Disabled in this field.
The settings are: Enabled and Disabled.
