Interrupt Map
Hardware Interrupts (IRQs) are supported for both PC/104 (ISA) and PCIe devices. The user must reserve IRQs in the
BIOS CMOS configuration for use by legacy devices. The PCIe/PnP BIOS will use unreserved IRQs when allocating
resources during the boot process. The table below lists IRQ resources as used by the PCM-VDX-2-512.
IRQ0 18.2 Hz heartbeat
IRQ1 Keyboard
IRQ2 Chained to Slave controller (IRQ9)
IRQ3 COM2 *
IRQ4 COM1 *
IRQ5 USB/On-board Ethernet
IRQ6 USB
IRQ7 LPT *
IRQ8 Real-Time Clock
IRQ9 COM3 *
IRQ10 Available
IRQ11 COM4 *
IRQ12 Mouse
IRQ13 Floating point processor
IRQ14 IDE
IRQ15 Available
*
These IRQ references are default settings that can be changed by the user in the CMOS Settings
utility. Reference the PCI Configurations section under Advanced Settings.
**
IRQ9 is commonly used by ACPI when enabled and may be unavailable (depending on operating
system) for other uses.
*** IRQ15 is currently unavailable under the Windows operating systems.
Some IRQs can be freed for other uses if the hardware features they are assigned to are not being
used. To free an interrupt, use the CMOS setup screens to disable any unused board features or their
IRQ assignments.
