Installing PC Cards
Note the following when installing these cards:
Note
Depending on the configuration of the Box PC, there may not be any free interrupts
available for operating PC Cards. You have to reserve the necessary PC card inter-
rupts in the BIOPS setup menu as follows:
Set the necessary interrupt via Advanced > PCI-Configuration >
PCI/PNP ISA IRQ Resource Exclusion to “reserved” (default: available).

Caution
Risk of damage to PC cards and the Box PC!
Always insert PC cards with the front face turned toward the rear of the Box PC.
The front face generally bears the company and product designation and is la-
beled ”This side up”, or words to that effect.
You might damage the Box PC and the PC card if you attempt to insert the PC
card the wrong way round.
Before inserting the connecting cables, the electrostatic charge in your body, the
device and the connecting cables must be brought to the same potential. Briefly
touch the sheet metal case to do this.
Notice
In order to use a PC card the BIOS-SETUP Main > Hardware Option
“Cardbus/PCMCIA Slot” has to be set to “Enabled”.
