8580/8590 Vehicle-Mount Computer User Manual 109
8.1 Chipset
The 8580/8590 computer is equipped with a chipset which controls the communication
between all function modules. The chipset converts the signals it receives from the CPU into
memory access, hard drive access and other similar actions. Likewise, it transmits requests
from peripheral devices to the CPU. Input devices such as the mouse or keyboard also com-
municate with the system via this chipset.
Resources
The chipset does not require any resources for its core functions – unlike the internal periph-
eral units, which are also described in this manual.
8.1.1 Installing Chipset Drivers Under Windows XP
The chipset drivers to be used can are stored on the Compact Flash or hard drive under
Util/chipset/<verNR> by default.
In addition, you will find the drivers on the driver CD shipped with your unit.
To install the chipset driver:
1. Open the corresponding folder and run Setup.exe.
1. Tap on Next.
Important: Install the chipset drivers before all other drivers; otherwise the system will
not function properly!
