Follow the messages hereinafter to protect your systems from damage on all occasions.

Touch a grounded metal object to discharge the static electricity in your body (or ideally, wear a grounded

wrist strap)

Stay safe from the electric shock. Don‘t touch any components of this card when the card is on. Always

switch off power when the system is not in use.

Disconnect power when changing any hardware devices. For instance, when you connect a jumper or install

any cards, a surge of power may damage the electronic components or the whole system.

AR-B1682 Connector, Jumper and Component Locations

2-3. HOW TO SET JUMPERS

A jumper consists of two or three metal pins with a plastic base mounted on the card, and a small plastic cap

(with a metal contact inside) to connect the pins, so you can set up your hardware configuration by "open" or

close the pins. The jumper can be combined into sets which called jumper blocks. When the jumpers are all

in the block, you have to put them together to set up the hardware configuration. The figure below shows how

it looks.

2 PIN 3 PIN

CAP

JUMPERS AND CAP

If a jumper has three pins, for example, labelled PIN1, PIN2, and PIN3, you can either connect PIN1 & PIN2 to

create one setting and shorting or connect PIN2 & PIN3 to create another setting. The jumper setting rules are

applied throughout this manual.

(1) DOC Memory Mapping Selection (JP6, JP7)

A 32-pin DOC socket supports a DOC (Disk-on-Chip) up to 72Mb. This PnP Flash ROM DOC can

be installed as one of the user’s hard disk drive. And if set as Drive C, it can be used to boot up

the computer with MS-DOS installed. It offers much faster access than a floppy or hard disk and

greatly increases reliability under harsh environment.

The DOC Memory Mapping is as follows:
