33 .Nd Device driver for the I/O bus
39 have a 16-bit I/O bus connected to the CPU bus by bi-directional buffers
40 managed by the IOC. The
42 driver provides support for this bus. All
44 kernels need this driver.
46 On Archimedes systems, the only device attached at
48 is the IOC. While MEMC podules are physically
50 devices, they're logically treated as being attached to the IOC. On
51 machines with an IOEB, the Universal Peripheral Controller chip is also
