Operating condition:
Due to this feature is addressing from ISA bus!
So, the ISA Bridge (IT8888G) must present on system for this feature support.
H/W jumper:

Pin 1-2 *
+3.3V
Pin 3-4
+5V
S/W Port Address
: Output (0x300), Input (0x301).
Sample code
(using TurboC/C++ 3.0):
#define WRITE_OUT 0x300
//8bit I/O output
#define READ_IN 0x301
//8bit I/O input
unsigned
char
val=0;
val=inportb(READ_IN);
//Read 8 bits data from DIO port
outportb(WRITE_OUT,val);
//Write 8 bits data to DIO port
