0.7 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 comp onents. Although areas with humid climates are much less prone to static build-up, it is always best to safeguar d against acci dents 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.

2.2 SYSTEM SETTINGS
Jumper pins allow you to set specific system parameters. Set them by changing the pin loc ation of the jumper blocks. (A jumper block is a small plastic-encased conductor that slips over the pins.) To change a jumper setting, remove the jumper from its current location with your fingers or small needl e-nosed pliers. Place the jumper over the two pins designated for the desired setting. Press the jumper evenly onto the pins. Be careful not to bend the pins.
We will show the locations of the AR-B1690 jumper pins, and the factory-default settings.
CAUTION: Do not touch any electronic components unless you are safely grounded. Wear a grounded wrist strap or touch an exposed metal part of the system unit chassis. The static discharges from your fingers can permanently damage electronic components.

2.2.7 USB Connector (USB1 & USB2)
The Universal Serial Bus (USB) controller is USB V1.1 and Universal H CI V1.1 compliant. The Universal Serial Bus (USB) standard is a low-to-medium speed interface for the connection of PC peripherals, which gives complete Plug & Play, and hot attach/detach for up to 127 external devices. USB is a leading edge technology that allows the user to quickly and easily add a wide range of peripheral devices from printers to keyboards and telephony devices to fax/modems. Universal Host Controller Interface (UHCI) and future support for the Open Host Controller Interface (OHCI) ensure USB compatibility and usability well into the future. The CPU board supports four Universal Serial Bus ports. An optional external port bracket attaches to the onboard connector via an attached cable. With the optional port bracket installed you can attach USB devices to the external ports. If the USB ports are installed, the USB Controller line in the Integrated Peripherals section of the CMOS Setup utility must be set to “Enabled”. USB ports may also require Operating System support for USB devices.

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 watchdo g 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 f ails to trigger the watchdog t imer before times out, it will generate a reset pulse to reset the system or trigger the IRQ 9 signal in order to tell your system that the watchdog time is out.
Please refer to the following table in order to properly program Watchdog function

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

4.2 WATCHDOG TIMER TRIGGER
After you enable the watchdog t imer, your program must write the same factor as triggering to the watchdog timer
at least once during every time-out period. You can change the time-out period by writing another timer factor to the watchdog register at any time, and you must t r igger the watchdog during every new time-out period in next trigger.

z BIOS Setup Overview z Standard CMOS Setup z Advanced CMOS Setup z Advanced Chipset Setup z Power Management z PCI/Plug and Play z Peripheral Setup z Auto-Detect Hard Disks z Password Setting z Load Default Setting z BIOS Exit
5.1 BIOS SETUP OVERVIEW
The BIOS is a program used to initialize and set up t he 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 consol e subsystem contains speci al software, called firmware that interacts directly with the hardware components and facil itates 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 manufact urer. 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.
Setup Main Menu
CAUTION:
1. AR-B1690 BIOS the factory-default setting is used to the <Auto Configuration with Optimal Settings> Acrosser recommends using the BIOS default setting, unless yo u are very familiar with the setting functi on, or you can contact the technical support engineer.
2. If the BIOS settings are lost, the CMOS will detect the <Auto Configuration with Fail Sa fe Settings> to boot the operation system, this option will reduce the performance of the system. Acrosser reco mmends choosing the <Auto Configuration with Optimal Setting> in the main menu. This option gives best-case values that should optimize system performance.
3. The BIOS settings are described in detail in this section.

5.2 STANDARD CMOS SETUP
The <Standard CMOS Setup> option allows you to record some basic system hardware configuration and set the system clock and error handling. If the CPU board is alread y installed in a working system, you will not need to select this option anymore.
Standard CMOS Setup
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 prom pts by creating an AUT OEXEC.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 BI OS supports <Pri Master>, <Pri Slave>, <Sec Mast er> 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.
You can select <AUTO> under the <TYPE> and <MODE> fields. This will enable auto detection of your IDE drives during boot-up. This will allow you to change your hard drives (with the power off) and t hen power on without having to reconfigure your hard drive type. If you use older h ard disk drives, which do not support this feature, then you must configure the hard disk drive in the standar d method as described above by the <USER> option.
Floppy Setup
The <Standard CMOS Setup> 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.
Boot Sector Virus Protection
This option protects the boot sector and partition tabl e of your hard disk against accidental modifications. Any attempt to write to them will cause the system to halt and display a warning message. If this occurs, you can either allow the operation to continue or use a bootable virus-free floppy disk to reboot and investigate your system. The default setting is < Installation of new operating systems requires that you disable this to prevent write errors.
Disabled>. This setting is recommended because it conflicts with new operating s ystems.
