Low Pin Count - This refers to standardized port designed and/or termed by Intel allowing for legacy free computers to have legacy devices; Another way of putting this is a computer with only USB ports can have a PS2, Serial, Parallel, Game port, etc ports attached through some circuitry into the LPC port. The LPC port can also be used to connect an IR port, Smart Card Reader, or External BIOS. The last one is the most important use for this document since these points are used in a 3rd generation chip install to connect mode of the modchip with fewer wires. This port header in the XBOX has 2 columns and 8 rows of pins (except one is not used.) The v1.0 XBOX has the holes filled with solder which can be carefully removed. This requires a little more work than usual, but is worth it because it is a very clean installation.
Low Pin Count. An Intel standard which is used, among other things, for non ISA-based Super I/O chips, designed with relatively few pins.
