Introduction

The SBC104 is a PC-compatible 386SX/486SXLC processor board supporting a 16-bit PC/104

interface which combined with a PC/104 VGA CRT/Flat Panel display module can form the complete

DOS compatible PC for embedded applications. The board is fitted with 2 or 4 Mbytes of DRAM, 1 or

2 Mbytes of FlashFilememory and optionally 128 Kbyte of battery backed SRAM. Systems BIOS

and extensions are contained in a 128 Kbyte EPROM. Onboard peripheral ports include COM1 and

COM2, a floppy disk controller, hard disk (IDE) controller, a parallel port (LPT1) and keyboard

interface.

Getting Started with the SBC104

How the SBC104 works

The SBC104 is a PC-compatible processor board. There are connections on the SBC104 for a

keyboard, floppy drive, a hard drive, two serial communication ports and a centronics parallel port.

There is also a PC/104 connector that will allow you to connect a PC/104 VGA board to form a

complete PC system environment.

The SBC104 board is supplied with Arcom Flash Filling System (AFFS) and ROM-DOS 6.22 pre-

loaded. ROM-DOS is a flexible, small and fast compatible DOS. More information on the differences

between ROM-DOS and the DOS standard can be found on the utilities disk under

A:\DOC\ROMDOS.DOC.

Using AFFS the on-board Flash memory appears exactly as a normal hard drive interface. All the

application software can be loaded onto the Flash and run exactly as if it were a standard hard drive.

There is no need to configure the on-board Flash memory in the BIOS set-up utility as the AFFS will

automatically configure the Flash as the C:\ drive. Any additional drives connected to the IDE

connector will be allocated as the next drive up (i.e. the D:\ drive). The on-board Flash can be

disabled for applications which are intended to have an external IDE drive as the C:\ drive (see

appendix on disabling the on-board Flash).

The SBC104 can be used either with or without a VGA/Keyboard interface. The SBC104 is factory

loaded with a simple AUTOEXEC.BAT file and a small program FINDVGA.EXE that detects the

presence of VGA card. If there is a VGA card fitted then the SBC104 can be used as exactly as any

PC. If there is no VGA card fitted then the SBC104 will re-direct output to the serial port COM1 which

should be connected to a PC terminal emulator or a PC with a windows terminal emulator. This kind

of operation is referred to as Remote Mode.

Before Powering up the board

Connect a +5v power supply to the power header PL5. The SBC104 does nnoottrequire ±12v to operate

so if any of the PC/104 boards connected to the SBC104 require a +12v or -12v power supply (such

as the AIM104-SER4) then connect these to PL5. Refer to the labelling on the board and the

appendix for the correct connections.

Battery back-up is necessary to maintain the CMOS BIOS settings. If a battery back-up voltage is not

present then the SBC104 will revert to its default settings. The battery link LK3 is isolated on the

SBC104 during shipment. Move LK3 to position A to enable the battery backup facility. If battery

backup is to be supplied from an external source instead of the on-board battery then connect

positive voltage from the backup supply (which must be +3.7) to +VBB and the ground to GND on

PL5. In this case LK3 should be removed completely.

Switching On

As the battery link has been removed during shipment the CMOS RAM may be corrupted and the

board will either need to be reconfigured or it will reset to its default CMOS settings These default

settings configure the SBC104 for a single floppy drive. To reconfigure the board to accept another

floppy or a hard drive then it is necessary to connect a PC/104 VGA board and a keyboard in order

to alter the parameters within the SET-UP utility (see appendix on configuring drives.).

Note: Even in this default configuration the SBC104 will boot successfully without a keyboard, floppy

or hard drive connected. There will, however, be an error message on boot-up that will indicate that

drive a:\ is not configured correctly.

EMC Chassis Point

The SBC104 has a clearly labelled EMC chassis point near the keyboard connector. This point serves

as a mounting hole for the PC/104 stack through modules. It should be connected to the earth point

of the enclosure.
