18.1 Interrupt Request (IRQ) 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

manufacturers 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.
