Some IRQs may not be available to the ISA bus due to operating system limitations.
- IRQ 9 is used by the ACPI SCI (System Control Interrupt) by default, and requires a

- IRQ 10 is used for PCI IRQ routing, and usually requires a custom BIOS for use on
the ISA bus.

Make sure to correctly configure the PCI slot position jumpers on each PC/104- Plus or PCI-104
module appropriately.
The BIOS automatically allocates I/O, memory, and interrupt resources.
