Introduction

WAFER-6820 is designed for limited space applications with only the
size of a 3½" hard drive. It supports the full functions of an AT-compatible
industrial computer on a single board. The WAFER-6820 is equipped with a
low-power consumption and high performance Transmeta TM3200
processor on board. It also contains an SDRAM SODIMM socket that can
support up to 128MB memory.

The WAFER-6820 provides an Ethernet interface, audio interface,
Compact Flash Type II, EIDE interface, one parallel port, one serial port
RS-232, one serial port RS-232/422/485 with auto-direction, and a mini-DIN
PS/2 keyboard/mouse interface. The built-in SVGA/LCD display controller
supports both the CRT and LCD display simultaneously. It offers the
resolutions of LCD screen up to 1024 x 768 and CRT resolutions up to 1280
x 1024 @ 16 colors. The display type is configured by software utility. The
Flash ROM contains both the system BIOS and the VGA BIOS.
Reprogramming the Flash ROM could do the modification, in case of
necessary.

The RS485 has an outstanding characteristic of intelligent directing
control, which eliminates the extra control signal like RTS. With this feature
you can develop your program as you are using a normal RS232 without
special control routine. This is especially important in WINDOWS
programming which do not allow the program to catch the control pin at

1

your wish.

Finally, one PC/104 connector is included for the future application you

will need.

Notes:

The Transmeta Crusoe™ TM3200 will occupy 16MB memory space to
save its CMS code temporally. So we must indicate the memory type for
Tramsmeta Crusoe™ TM3200. Because this point, we will attaché one
128MB SDRAM module that we approved in the package.

2.3 Unpacking

Your WAFER-6820 Single Board Computer contains sensitive
electronic components that can be easily damaged by static
electricity.

In this section, we describe the precautions you should take while
unpacking, as well as during installation. It is very important that the
instructions be followed correctly, to avoid static damage, and to
successfully install the board.

The system board should be done on a grounded anti-static mat.
The operator should be wearing an anti-static wristband, grounded
at the same point as the anti-static mat.

Inspect the cardboard carton for obvious damage. Shipping and
handling may cause damage to your board. Be sure there are no
shipping and handing damages on the board before processing.

After opening the cardboard carton, exact the system board and
place it only on a grounded anti-static surface component side up.

Again inspect the board for damage. Press down on all the
docketed IC's to make sure that they are properly seated.
Do this only with the board place on a firm flat surface.

Note: DO NOT APPLY POWER TO THE BOARD IF IT HAS BEEN

DAMAGED.

You are now ready to install your WAFER-6820 Single Board
Computer.

AWARD BIOS Setup

The WAFER-6820 uses the AWARD PCI/ISA BIOS for system
configuration. The AWARD BIOS setup program is designed to provide
maximum flexibility in configuring the system by offering various options,
which may be selected for end-user requirements. This chapter is written to
assist you in the proper usage of these features.

4.1 Introduction

This chapter discusses the Setup program built into the BIOS. The Setup
program allows users to configure the system. This configuration is then
stored in battery-backed CMOS RAM so that it retains the Setup
information while the power is off.

4.2 Starting Setup

The BIOS is immediately active when you turn on the computer. While the
BIOS is in control, the Setup program can be activated in one of two ways:

1. By pressing <Del> immediately after switching the system on, or

2. By pressing the <Del> key when the following message appears briefly
at the bottom of the screen during the POST (Power On Self-Test).

Press DEL to enter SETUP.

25

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" button on the system case. You may also restart by
simultaneously pressing <Ctrl>, <Alt>, and <Delete> keys. If you do not
press the keys at the correct time and the system does not boot, an error
message will be displayed and you will again be asked to...

PRESS F1 TO CONTINUE, DEL TO ENTER SETUP

4.3 Using Setup

In general, you can use the arrow keys to highlight items, press <Enter> to
select, use the PageUp and PageDown keys to change entries, press <F1>
for help and press <Esc> to quit. The following table provides more details
about how to navigate in the Setup program using the keyboard.

4.4 Main Menu

Once you enter the AwardBIOS™ CMOS Setup Utility, the Main Menu will
appear on the screen. The Main Menu allows you to select from several
setup functions and two exit choices. Use the arrow keys to select among
the items and press <Enter> to accept and enter the sub-menu.

PASSWORD DISABLED.
When a password has been enabled, you will be prompted to enter it every

time you try to enter Setup. This prevents an unauthorized person from
changing any part of your system configuration.

Additionally, when a password is enabled, you can also require the BIOS to
request a password every time your system is rebooted. This would
prevent unauthorized use of your computer.

You determine when the password is required within the BIOS Features
Setup Menu and its Security option (see Section 3). If the Security option is
set to password will be required both at boot and at entry to Setup. If set to
“Setup”, prompting only occurs when trying to enter Setup.

4.13 Exit Selecting

Save & Exit Setup

Pressing <Enter> on this item asks for confirmation:
Save to CMOS and EXIT (Y/N)? Y
Pressing “Y” stores the selections made in the menus in CMOS – a

special section of memory that stays on after you turn your system
off. The next time you boot your computer, the BIOS configures
your system according to the Setup selections stored in CMOS.
After saving the values the system is restarted again.

Exit Without Saving

Pressing <Enter> on this item asks for confirmation:
Quit without saving (Y/N)? Y
This allows you to exit Setup without storing in CMOS any change.

The previous selections remain in effect. This exits the Setup utility
and restarts your computer.

Appendix A. Watch-Dog Timer

The Watchdog Timer is a device to ensure that standalone systems can
always recover from abnormal conditions that cause the system to crash.
These conditions may result from an external EMI or a software bug. When
the system stops working, hardware on the board will perform hardware
reset (cold boot) to bring the system back to a known state.

Three I/O ports control the operation of Watchdog Timer.

443 (hex) Write Set Watchdog Time period
443 (hex) Read Enable the refresh the Watchdog Timer.

043/843 (hex) Read Disable the Watchdog Timer.
Prior to enable the Watchdog Timer, user has to set the time-out period.
The resolution of the timer is 1 second and the range of the timer is from 1
sec to 255 sec. You need to send the time-out value to the I/O port – 443H,
and then enable it by reading data from the same I/O port – 443H. This will
activate the timer that will eventually time out and reset the CPU board. To
ensure that this reset condition won’t occur, the Watchdog Timer must be
periodically refreshed by reading the same I/O port 443H. This must be
done within the time-out period that is set by the software, please refer to
the example program. Finally, we have to disable the Watchdog timer by
reading the I/O port -- 843H or 043H. Otherwise the system could reset
unconditionally.

A tolerance of at least 5% must be maintained to avoid unknown routines in the
operating system (DOS), such as disk I/O that can be very time-consuming.
Therefore if the time-out period has been set to 10 seconds, the I/O port 443H
must be read within 7 seconds.

Example assembly program:

TIMER_PORT = 443H
TIMER_START = 443H
TIMER_STOP = 843H
