Antennas
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.
