BIOS in the single board computer is a customized version of the industrial standard
BIOS for IBM PC AT-compatible computers. It supports Intel x86 and compatible CPU
architecture based processors and computers. The BIOS provides critical low-level
support for the system central processing, memory and I/O sub-systems.

The BIOS setup program of the single board computer let the customers modify the basic

configuration setting. The settings are stored in a dedicated battery-backed memory,
NVRAM, retains the information when the power is turned off. If the battery runs out of
the power, then the settings of BIOS will come back to the default setting.

The BIOS section of the manual is subject to change without notice and is provided h ere

simple IN/OUT commands.The following lines show an example how to
do this.

GPIO0…..GPIO7 bit0……bit7

-o 2 E 87 ;enter configuration

-o 2E 87

-o 2E 07

-o 2F 09 ;enale GPIO function

-o 2E 30

-o 2F 02 ;enable GPIO configuration

-o 2E F0

-o 2F xx ;set GPIO as input/output; set ‘1’ for input,’0’for
output

-o 2E F1

-o 2F xx ;if set GPIO’s as output,in this register its value can
be set

Optional :

-o 2E F2

-o 2F xx ; Data inversion register ; ‘1’ inverts the current valus
of the bits ,’0’ leaves them as they are

-o 2E 30

-o 2F 01 ; active GPIO’s
