5.1.1.2 Programming Guide
To program the Super I/O chip F81866A configuration registers, the following configuration
procedures must be followed in sequence:
(1) Enter the Extended Function Mode
(2) Configure the configuration registers
(3) Exit the Extended Function Mode
The configuration register is used to control the behavior of the corresponding devices. To
configure the register, use the index port to select the index and then write data port to alter
the parameters. The default index port and data port are 0x4E and 0x4F, respectively.
To
enable configuration, the entry key 0x87 must be written to the index port. To disable
configuration, write exit entry key 0xAA to the index port.
Following is an example to
enable configuration and to disable configuration by using debug.
