2.1.8 DiskOnChip Flash Disk (Yellow Jumper Cap) (This function and jumper are optional)

Installation Instructions

1. Make sure the motherboard is powered OFF.

2. Plug the DOC (DiskOnChip) device into its socket. Verify the direction is correct. (pin 1 of the

DiskOnChip is aligned with pin 1 of the socket)

3. Set Base address 1-2 : D0000H(Default Setting) 3-4 : D8000H

4. Power up the system.

5. During power up you may observe a message displayed by the DOC when its drivers are

automatically loaded into system's memory.

6. At this stage the DOC can be accessed as any disk in the system.

7. If the DOC is the only disk in the system, it will appear as the first disk (drive C: in DOS)

8. If there are more disks besides the DOC, the DOC will appear by default as the last drive, unless it

was programmed as first drive. (Please refer to the DOC utilities user manual)

9. If you want the DOC to be bootable:

I. Copy the operating system files into the DOC by using the standard DOS command ( for

example: SYS D: )

II. The DOC should be the only disk in the systems or should be configured as the first disk in

the system ( C: ) using the DUPDATE utility For more information on DiskOnChip, visit M-

Systems Web site at http://www.m-sys.com

where you can find Utilities Manual, Data Sheets and Application Notes. In addition, you can find the latest
DiskOnChip S/W Utilities.

2.2 Installation of CPU

Before installing CPU, make sure the power is off. Locate the white color level bar on the ZIF socket. Push
level bar away from the socket and pull upward 90 degrees. Insert the CPU into the socket. Make sure the
notch of the CPU corresponds with the white dot on the ZIF socket (the corner without pin socket). Do not
push in the CPU. Make sure all pins are aligned with the CPU socket. ON the level bar.

2.3 Installation of Memory

Please start inserting memory module from DIMM 1 (white) socket.

This motherboard has 3x168-pin 64-bit DIMM sockets divided into 3 banks. Make sure you fill up each
bank and use the same brand and same capacity memory in the same bank. This will increase the system
reliability.

Under ACPI (advanced configuration and power interface ) the system can be turned off mechanically ( by
the power button ) or it can undergo a software power off. If the system has been turned off by software, the
system can be resumed by a Alarm wake up signal. This item allows you to define a software power off
using the power button. If the value is set to Instant-Off, the power button will automatically cause a
software power off. If the value is set to Delay 4 Sec. The power button must be held down for a full four
seconds to cause a software power off.

the “Standard CMOS Setup” automatically.

This routine only detects one set of parameters. If your hard disk is formatted using different parameters
than those detected, you have to enter the parameters manually. If the parameters listed do not match the
ones used to format the disk, the information on that disk will not be accessible. If the auto-detected
parameters displayed do not match those that are used for your drive, ignore them. Type N to reject the
values and enter the correct ones manually from the Standard CMOS Setup screen.
