Interrupt Requests and I/O Assignments

Caution

Each hardware resource in the system must be assigned a unique interrupt request (IRQ) number and an I/O address range. If these settings overlap, the system will not function properly.

Below is a list of the factory-set IRQs and addresses used in the system, and whether they are available for add-in cards. Problems can be avoided if add-on devices use the IRQs and address ranges labeled "Available". If necessary, the touch screen and network card settings can be changed to accommodate new hardware that will only work at the settings used by these devices. The directions for changing the touch screen settings are provided in this document. Utilities for changing network card settings are in the C:NWCARD directory.
