Introduction
Welcome to the SSC-5x86H Super 5x86 Half-sized Single
Board Computer. The SSC-5x86H board is an ISA and
PC/104 form factor board, which comes equipped with high
performance 486DX/DX2/DX4 or the latest Cyrix/AMD 5x86
CPU and advanced high performance multi-mode I/O,
designed for the system manufacturers, integrators, or VARs
that want to provide all the performance, reliability, and
quality at a reasonable price.
An advanced high performance super AT I/O chip UMC
UM8669 is used in the SSC-5x86H board. Both on-chip
UARTs are compatible with the NS16C550. The parallel port
and IDE interface are compatible with IBM PC/AT and XT
architecture's. The UM8669 incorporates sophisticated power
control circuitry(PCC). The PCC supports multiple low power
down modes.
In addition, the SSC-5x86H provides two 72-pin SIMM sockets for
its on-board DRAM. The 72-pin accepts 1MB, 2MB, 4MB, 8MB,
16MB, and 32MB SIMM. So, the total on-board memory can be
configured from 1MB to 64MB.
SSC-5x86H uses the ALI chipset, M1489 and M1487, which
are 100% ISA compatible chipset.
The new Ver.C board have built-in DiskOnChip Flash Disk
Function and ESD +/-15KV protection RS-232 ports. The new
version will only need +5V power supply. It will be more
suitable for embedded application.

Installation
This chapter describes how to install the SSC-5x86H. At first,
the layout of SSC-5x86H is shown, and the unpacking
information that you should be careful is described. The
jumpers and switches setting for the SSC-5x86H's
configuration, such as CPU type selection, system clock
setting, and interrupt IRQ setting for serial ports and parallel
port, are also included.

2.2 Jumper Description
You can change the SSC-5x86H's configuration by setting jumper
switches on the board. The board's jumpers are preset at the factory.
Under normal circumstances, you should not need to change the
jumper settings.
A jumper switch is closed (sometimes referred to as shorted with
the plastic cap inserted over two pins of the jumper). A jumper is
open with the plastic cap inserted over one or no pin(s) of the
jumper. Figure 2.2 below shows different jumper settings which
will be used in this chapter.
