The LPC Bus LPC Bus-Legacy Lives On With all the advances in
processor and I/O technology, what has become of the venerable
I/O devices that are still so useful for a wide range of
applications? The preservation of the LPC bus offers a low-cost
and straightforward way to continue using these legacy devices.

Legacy buses and I/O appear to be on the chopping block. Large
pin count parallel communications buses are being replaced by
faster serial architectures. Examples include Serial ATA (SATA)
replacing IDE/Parallel ATA (PATA) and PCI Express replacing
parallel PCI. After the ISA bus was phased out of the modern x86
chipsets, the major semiconductor companies realized that users
were critically concerned about how to attach relatively low-
speed serial and parallel devices. Typically these devices would
be a super-I/O device or a boot ROM. Electronics system
manufacturers request the continued availability of simple, low-
cost I/O that would give them
