LPC bus (Low Pin Count)

What's LPC ? (from LPC bus in Plug-and-Play-HOWTO)

* a type of slow bus, used for slow "legacy" devices such as serial ports, floppy devices, etc.

* replace old ISA bus: LPC needs fewer pins, and uses a faster clock speed

* its bus for data/address and control is only 4 bits wide (so "low pin count")

* all LPC devices are on-board; there are no LPC slots

* a major chip on the LPC bus is the superio chip
