Controllers • System Units with Socket 370
Display units developed for Provit 2000 series IPCs cannot be used together with a
Provit 5000 series IPC.
8.13.3 Use of an External Graphic Card
It is possible to operate an external graphic card in a PCI slot on the mainboard. If such a card
is inserted, it is automatically recognized during the start-up procedure and the onboard VGA
controller automatically switches itself off. It is not possible to manually switch the VGA controller
on and off.
An external graphic card cannot be operated in an ISA slot.
By deactivating the onboard VGA controller, it is not possible to operate a display or
monitor to the IPC's FPD and CRT interfaces using an external graphic card, as these
are switched off.
8.13.4 Relationship between Resolution, Graphic memory and Colors
The following table applies to all graphic controllers and display units. It should be noted that with
high resolutions (XGA, SXGA) the number of colors is very limited.
