*The onboard hardware monitor uses the address 290H-297H so legacy ISA cards must not use this address otherwise conflicts will occur.

†PCI slots 4&5 share the same interrupt number (INT#) so PCI cards on these two slots must be able to share an INT# or make sure that one of these PCI cards does not use an INT#.
