Moxa Technologies CP-104UL user manual Each board must occupy one unique IRQ and four 8-byte I/O

Note!	Each board must occupy one unique IRQ and four 8-byte I/O
	addresses, which are assigned automatically by the PCI BIOS.
	However, you can select a free IRQ number manually via the PC’s
	BIOS setup for the PCI slot, but normally this method is not
	available for the I/O address. The possible IRQ numbers are 2, 3, 4,
	5, 7, 10, 11, 12, and 15. The possible I/O addresses are from
	0x0000 to 0xFFFF.
