A.1 Interrupt Request Lines
Please note that Kontron PC/104 devices were designed after the draft of P996 Specification for ISA
systems. Because of this, shareable interrupts are not supported. Some PC/104 add-on board manu-
facturers do not follow the P996 Specification and allow shareable interrupts. If you want to use such
PC/104 boards with Kontron devices, contact the manufacturer of the add-on board and ask about switching
to non-interrupt sharing. Please ensure that the chosen interrupt is not already in use by a PCI device.
