Taking Over Where ISA Leaves Off
Intel introduced the LPC specification in 1998. The LPC bus standard provides a local bus on a platform with no device sockets, resulting in savings for both manufacturer and customer. Intel's standard consists of a minimum of seven signals and a clock speed of 33 MHz. You do not need any software modifications to enable migration to the LPC bus from the ISA bus. This is a big and unusual advantage, since most hardware changes require software modification. Legacy I/O peripherals that used the ISA bus, such as the mouse, keyboard, floppy disk drive, infrared, and parallel ports, are supported by a companion Super I/O circuit. This circuit has also migrated from the ISA bus to the LPC bus, improving system integration. Intel has also developed a new BIOS chip, called a Firmware Hub (FWH) that supports the LPC bus to replace the traditional BIOS chip that uses the ISA bus.

Tnx, but what about the joystick? is it connected to any bus?
