Appendix3：GPIO Instruction
MITX-6891 provides a five way input and a five way output programable interface. Input
and output of the interfaces are independent. In the GPIO interface, there are 12 Pin which are
link to 10 digital bits. This interface is generated by the onboard chip on PCI bus, and the bus
number is 0, device number is 18 and function number is 0. This interface is using the 3rd basic
address register.
According to PCI standard, the basic address are allocated by the BIOS
dynamically, and it is a MUST normally to obtain the basic address before program this
interface(if there are no other PCI expansion device, the basic address is: CC00H).
GPIO's interface debugging program is attached in the CD of the packinglist. Running the
GPIO executable file will start the GPIO debug program.

allow OS to control most power of computer and its extended devices. Windows 98/98SE,
Windows 2000 and Windows ME are all support ACPI, it provide users a flexible system power
management.
ATX
AT extended, a motherboard layout according with modern standard replaced BabyAT. It
changes disposal of many components, and do some new high efficiency design, so it is widely
used now.
BIOS
Basic in/out system.It’s a kind of software including all in/out control code interface in PC.
It will do hardware testing while system booting, then system runs, it provides an interface
between OS and hardware. BIOS is stored in a ROM chip.
BUS
In a computer system, it’s the channels among different parts for exchanging data; it’s
also a group of hardware line. BUS here means part lines inside CPU and main components of
memory.
Chipset
Integrated chips for executing one or more function.Here “Chipset” means system level
chipset structured by Southbridge & Northbridge; it decides motherboard’s structure and main
functions.
CMOS
Complementary Metal-Oxide Semiconductor, a widely used semiconductor with the
characteristic of high speed but low power. CMOS we mention here means part of obligate
