Setup
Many options provided on the Little Board P6d system are controlled by the Setup function. The
parameters are displayed on several screens, selected from a main menu screen. To configure the
board, you modify the fields in these screens and save the results in the on-board configuration
memory.
The configuration memory consists of portions of the CMOS RAM in the battery-backed real-time
clock chip and an Ampro-unique configuration EEPROM. To enhance embedd ed-sy stem reliability ,
the contents of the EEPROM mirror the contents of the CMOS memory. The EEPROM retains your
configuration information even if the clock’s backup battery fails.
The Setup information is retrieved from configuration memory when the board is po were d up or
when it is rebooted with a CTL-ALT-DEL key combination. Changes m ade to the Se tup par amete rs
(with the exception of the real-time clock time and d ate settin gs) d o no t take ef fec t until the system
is rebooted.
The Setup program is located in the ROM BIOS. To access Setup, press DEL while the computer is
in the Power On Self Test (POST), just prior to booting. This is called hot ke y access. The screen
will display a message indicating when entering DEL will access Setup.
Some Setup fields, for example, the amount of DRAM memory installed on the board, are read-only
fields, intended for informational purposes only.
