3.7.9  Antennas

If a PC card radio is installed in one of the 8570 PCMCIA slots, the antenna may be 
internal or external. When equipped with an antenna, the 8570 has a dome cover on 
the top left of the computer. The type of dome cover depends on the antenna used: 
plastic cover for an internal antenna, and a metal cover for an external antenna. For a 
description of available antennas, please see page 59.

3.8  Installing Software

Some accessories require that you install software drivers on the system. There are 
four ways to copy/install a software driver to the 8570:

1. Use a PCMCIA disk containing the software driver.

2. Boot the computer from an external USB floppy drive (see page 38).

3. Use an “interlink” cable to another computer containing the software 

driver (this assumes that a communication card with software driver is 
already installed).

4. Use an external CD-ROM player, connected through the PC card slot 

(this assumes that software for the CD-ROM is already installed) (see 
page 37).

3.9  The BIOS Firmware

Normally, the BIOS firmware should not be accessed. All settings, i.e. date and time 
etc., should be programmed though the interface of the operating system, as on any 
non-rugged PC. In exceptional cases the BIOS is available for use. For instance, 
if the 8570 function is abnormal or unstable, you can restore the computer to the 
default CHIPSET settings. Date and time can be changed within the BIOS 
firmware.

1. Attach an external keyboard to the 8570.

2. Power up the 8570.

3. Press the <F2> key on the keyboard while the 8570 is booting, to enter 

the BIOS setup.

4. Use the arrow keys to navigate through the BIOS firmware. 

5. Press <F9> to restore the default CHIPSET values.
