DESCRIPTION The system includes a machine-independent PCI bus subsystem and several machine-independent PCI device drivers. Note that interrupt mappings on the i386 may require that you conﬁgure your BIOS to reserve sufﬁcient in- terrupts as PCI/ISAPnP so that there are sufﬁcient interrupts remaining to conﬁgure the discovered PCI de- vices. For more information, see pcibios(4). OpenBSD provides support for the following devices. Note that not all architectures support all devices.
