1. Description

This USB Flash Disk works as a friendly, secure, and lightweight removable mass storage device disk. It plugs thru the USB port so your computer will immediately detect and configure the disk without needing to restart the computer. You read, write, copy and delete files just the same way as you use a disk drive. You can even play MP3 files, run applications or play videos directly from the USB Flash Disk. This USB Flash Disk is so light and compact that you can carry it with you anywhere. It comes in various storage capacities starting at 16MByte up to 512MByte. It is easy to install that you can actually use the USB Flash Disk to replace your floppy diskettes, ZIP drives, and even CD-RW discs. And because it uses durable solid-state storage flash memory, there are no moving parts inside making it shock resistant and longer to use. Unlike most USB Flash disks, this product provides an Mformat tool to help user partitioning the USB Flash Disk. This tool allows you to create two partition drives one standard open drive and one secured (password-controlled) drive. The secured drive requires a password before one can access it. Through this tool, the USB Flash Disk also can be set security feature that allows you to protect the data stored in USB Flash Disk. You can also use the tool to set your USB Flash Disk to be a bootable disk.

1.6 What is AGP? ?

The Accelerated Graphics Port (AGP) is a new port on the Host-To-PCI bridge device that supports an AGP port. The main purpose of the AGP port is to provide fast access to system memory. The AGP port can be used either as fast PCI port (32-bits at 66MHz vs.32-Bits at 33MHz) or as an AGP port which supports 2x data-rate, a read queue, and side band addressing. When the 2x-data rate is used the port can transmit data at 533MB/sec (66.6*2*4). The read-queue can be used to pipeline reads removing the effects of the reads-latency. Side band addressing can be used to transmit the data address on a separate line in order to speed up the transaction.

3.4. DRAM INSTALLATION

The main board can be installed with 8 / 16 / 32 / 64 / 128 / 256 MB 168 pins DIMM module DRAM, and the DRAM speed must be 67~100 MHz for SDRAM when system bus speed is set to 66MHz. When system bus speed is set to 100MHz, 100MHz SDRAM is required. The DRAM memory system on main board consists of bank 0, 1& bank 2. Since 168 pins DIMM module is 64 bits width, therefore 1 piece of DIMM module may match a 64 bits system. The total memory size is 8 MB ~ 768MB SDRAM. The DRAM installation position refer to Figure 3.1, and notice the Pin 1 of DIMM module must match with the Pin 1 of DIMM socket. Insert the DRAM DIMM module into the DIMM socket at Vertical angle. If there is a wrong direction of Pin 1, the DRAM DIMM module could not be inserted into socket completely.

3.5. CPU SPEED SETUP

The system bus speed can be set to 66.6 / 100MHz form the DIP SWITCH (SW1). The user can change the DIP SWITCH (SW2) selection to set up the CPU speed for different processors. The CPU speed must match with the frequency RATIO and Front Side Bus (FSB) speed. It will cause system hanging up if the frequency RATIO and FSB Speed do not match with the CPU.

M The CPU is a sensitive electric component and it can be easily
damaged by static electricity, so users must keep it away from metal surface when the CPU is installed onto main board.

3.6. CMOS RTC & ISA CFG CMOS SRAM
There're RTC & CMOS SRAM on board; they have a power supply from external battery to keep the DATA inviolate & effective. The RTC is a REALTIME CLOCK device, which provides the DATE & TIME to system. The CMOS SRAM is used for keeping the information of system configuration, so the system can automatically boot OS every time. Since the lifetime of internal battery is 5 years, the user can change a new Battery to replace old one after it cannot work. M Danger of explosion if battery is incorrectly replaced. M Replace only with the same or equivalent type recommended by the manufacturer. M Dispose of used batteries according to the manufacturers instructions.
3.7. SPEAKER CONNECTOR INSTALLATION
There is a speaker in AT system for sound purpose. The 4 - Pins connector SPK is used to connect speaker.
3.8. HARDWARE RESET SWITCH CONNECTOR INSTALLATION
The RESET switch on panel provides users with HARDWARE RESET function. The system will do a cold start after the RESET switch is pushed and released by user. The RESET switch is a 2 PIN connector and should be installed to RST on main board.
3.9. POWER LED CONNECTOR INSTALLATION
System has Power LED lamp on the panel of case. The Power LED will light on off or flash to indicate which step on the system. The connector should be connected to PWR of main board in correct direction.
3.10. IDE & ATAPI DEVICE INSTALLATION
There are two-Enhanced PCI IDE ports (IDE1, IDE2) on board, following ATAPI standard SPEC. Any one IDE port can connected ATAPI devices (IDE Hard Disk, CD-ROM & Tape Driver), so total four devices can exist in a system. The HD is the active LED port for devices. which to two ATAPI ATAPI
3.11. PERIPHERAL DEVICE INSTALLATION
After the I/O device installation and jumpers setup, the main board can be mounted into the case and fixed by screw. To complete the main board installation, the peripheral device could be installed now. The basic system needs a display interface card. If the PCI - Bus device is to be installed in the system, any one of four PCI - Bus slots can be used.
3.12. KEYBOARD & PS/2 MOUSE INSTALLATION
The main board supports PS/2 Mouse (J2). The BIOS will auto detect whether the PS/2 Mouse is installed or not & assign IRQ12 for PS/2 Mouse port if it is installed. After installing the peripheral device, the user should check everything again, and prepare to power-on the system.

BIOS Configuration

Award's BIOS ROM has a built-in Setup program that allows users to modify the basic system configuration. This type of information is stored in batterybacked CMOS SRAM so that it retains the Setup information when the power is turned off.

4.1. ENTERING SETUP

Power ON the computer and press <Del> immediately will allow you to enter Setup. If the message disappears before you respond and you still wish to enter Setup, restart the system to try again by turning it OFF then ON or pressing the "RESET" bottom on the system case. You may also restart by simultaneously press <Ctrl>, <Alt>, and <Del> keys.

4.2. CONTROL KEYS
