Drivers
The riser card is fully transparent for all operating systems – i.e. drivers are not required.
Some plug-in cards that are inserted into riser cards may require additional drivers. These
drivers must be supplied by the respective card manufacturers.
8.6 Cardbus Interface
The optional Cardbus slot is located beneath the antenna dome at the top of the 8580/8590.
It can be used for both PC Card (16 bit) and Cardbus (32 bit) cards.
The Cardbus slot has two options:
• Card Extender and Radio Dome
This option is designed to accommodate longer radio cards with integrated antenna (e.g.
WWAN cards).
• Cover
This option is designed to accommodate short cards.
8.7 Touchscreen
An optional resistive touchscreen is available for the 8580/8590. The touchscreen can be op-
erated with or without a keyboard and is compatible with a mouse.
Explanation of Functions
A touchscreen controller for resistive touchscreens is integrated into the motherboard to
analyze the sensor line state changes caused by touching. The touchscreen controller calcu-
lates and formats this data and then sends it to the touchscreen software driver via the COM4
port or optionally the mouse-PS/2 port (interrupt-controlled). The driver converts the data
into pointer commands.
The analog touchscreen controller used for analysis provides a resolution of 4096 x 4096
pixels (12-bit horizontal and vertical).
Important: If the touch controller is configured as PS/2 touch (via jumpers), a mouse
cannot be connected to the external PS/2 mouse.
Note: Of course it is always possible to use a serial or a USB mouse at the same time as the
touchscreen.
