Chapter 1 General Information 1
Introduction
The SBC-770 is an all-in-one Pentium II processor based single
board computer (SBC) with a PCI Flat Panel controller, a PCI
100Base-Tx Ethernet interface. When using an Intel Pentium II
processor, the SBC-770 achieves outstanding performance that
surpasses any other SBC in its class. In addition, the onboard SSD
interface supports M-systems DiskOnChip 2000 series, memory
capacity from 2 MB to 144 MB.
Onboard features include two serial ports (one RS-232, one RS-232/
422/485), one multi-mode parallel (ECP/EPP/SPP) port, connector for
two USB (Universal Serial Bus) ports, a floppy drive controller, and
a keyboard/PS/2 mouse interface. The built-in high speed PCI IDE
controller supports Ultra DMA/33 mode. Up to four IDE devices
can be connected, including large hard disks, CD-ROM drives, and
tape backup drives, etc.
The SBC-770 also features power management to minimize power
consumption. It complies with the ACPI standard and supports
three types of power saving features: Doze mode, Standby mode,
and Suspend mode. In addition, the board's watchdog timer can
automatically reset the system or generate an interrupt in case the
system stops due to a program bug or EMI.
Highly integrated SBC
The SBC-770 is a highly integrated SBC that combines video and
network functions on a single computer board. It provides up to
1024 x 768 resolution @ 64K colors with on-chip 2MB SDRAM
display memory. Major onboard devices adopt PCI technology to
achieve outstanding computing performance when used with Intel
Pentium II level processors, making the SBC-770 one of the world's
best and most powerful all-in-one Single Board Computers.

This chapter describes how to set up the
main board hardware, including instructions on setting jumpers and connecting
peripherals, switches, and indicators. Be
sure to read all the safety precautions
before you begin the installation procedure.

Jumpers and connectors
Connectors on the board link it to external devices such as hard
disk drives, a keyboard, or floppy drives. In addition, the board
has a number of jumpers that allow you to configure your system
to suit your application.

Setting jumpers
You can configure your card to match the needs of your application
by setting jumpers. A jumper is the simplest kind of electric switch.
It consists of two metal pins and a small metal clip (often protected
by a plastic cover) that slides over the pins to connect them. To
“close” a jumper you connect the pins with the clip. T o “open” a
jumper you remove the clip. Sometimes a jumper will have three
pins, labeled 1, 2, and 3. In this case you would connect either pins
1 and 2 or 2 and 3.

A pair of needle-nose pliers may be helpful when working with
jumpers.

your application, contact your local distributor or sales representative before you make any changes.

CPU installing and upgrading
Y ou can upgrade to a more powerful Pentium II CPU at any time.
Simply remove the old CPU, install the new one, and set the
jumpers for the new CPU speed.
Warning! Always disconnect the power cord from your
chassis when you are working on it. Do not
make connections while the power is on as
sensitive electronic components can be damaged by the sudden rush of power. Only experienced electronics personnel should open the
system chassis.
Caution! Always ground yourself to remove any static
charge before touching the system board.
Modern electronic devices are very sensitive to
static electric charges. Use a grounding wrist
strap at all times. Place all electronic components
on a static-dissipative surface or in a staticshielded bag when they are not in the chassis.
When you install a new CPU, be sure to adjust the board settings,
such as CPU frequency ratio. Improper settings may damage
the CPU.
Chapter 2 Installation 15
Mounting the CPU and cooling
Modules
The Pentium II is a module-type CPU which runs at high speeds,
for example 233 ~ 450 MHz, so the cooling mechanism becomes
critifal for system reliability . These are two types of cooling
methods: one with a cooling fan attached to the heat sink of the
Pentium II module, the other with a huge heat sink without any
cooling fan attached.
Both cooling methods for the Pentium II require a "retention
module" to firmly fix the Pentium II CPU to Slot 1. The following figures illustrate the steps involved in mounting the retention
module and installing the CPU and cooling modules.

Chapter 2 Installation 17
Installing DRAM (DIMMs)
System Memory
The left edge of the SBC-770 contains three sockets for 168-pin
dual inline memory module (DIMM). The socket uses 3.3 V
unbuffered synchronous DRAM (SDRAM). DIMM is available in
capacities of 16, 32, 64, or 128 MB. The socket can be filled in the
DIMM of any size, giving your SBC-770 single board computer
between 16 and 128 MB of memory.
Supplementary information about DIMM
Y our SBC-770 can accept both regular and PC-100 SDRAM DIMM
Module(with or without parity). However, if the Pentium II 350MHz
or up CPU is used, The SBC-770 can only accept PC-100 SDRAM
DIMM Module.
Single-sided modules are typically 16 or 64 MB; double-sided
modules are usually 32 or 128 MB.
Memory Installation Procedures
T o install DIMM, first make sure the two handles of the DIMM
socket are in the "open" position. i.e. The handles remain outward.
Slowly slide the DIMM module along the plastic guides on both
ends of the socket. Then press the DIMM module right down into
the socket, until you hear a click. This is when the two handles
have automatically locked the memory module into the correct
position of the DIMM socket. (See Figure below) T o take away the
memory module, just push both handles outward, and the memory
module will be ejected by the mechanism in the socket.
18 SBC-770 User Manual
Cache memory
Since the second level cache has been embedded into the Pentium® II CPU, you do not have to take care of either SRAM chips
or SRAM modules. The built-in second level cache in the Pentium
II yields much higher performance than the external cache memories. The cache size in the Pentium II CPU is either 256 KB or 512
KB. Normally, for workstation and server application, the 256 KB
version is enough. However, if your system is for heavy duty
applications, the 512 KB version will help a lot. Specifically for our
Pentium II based SBC, the Pentium II has another version that
provides much better data security if combined with the DRAM
ECC. Check with your vendor for various Pentium II models.
