4.1 Introduction
There are some SECOMX-945/N270 parameters that are important to set after a first board
optimisation, until a new change of hardware configuration.
It is possible to get this one using a user-friendly set-up that stores all parameters in an EEPROM:
these data are retained also after the board power off.
The access to Setup can be obtained before the bootstrap by pressing
CTRL+ALT+ESC
or
DEL
keys. Following this operation, it will appear the menu below:
To select, there are various possibilities, shown in the image above, while to execute them user
must press Enter. The same effect of selecting the last item can be obtained by pressing
ESC
.
First five items allow modifying setup parameters. They will be discussed more exhaustively in the
following paragraphs.
Sixth item shows hardware monitor values, so that onboard measured values of supply voltages
and CPU temperature will be displayed.
Seventh item is used to change the password required to enter into the setup menu (factory default
is a blank password, and it can be changed by the final user, in order to prevent unauthorised
accesses to this part of the system).
Eighth item restores CMOS situation to last known good values before any parameter modification.
Ninth item resets CMOS parameters to standard values (factory default) that can be adjusted to
most probable configuration in order to facilitate the system start in the case of unknown optimised
parameters.
The last two items allow exiting from setup respectively updating or not updating the C-MOS RAM.
It is important to remember that setup data are stored not only in a C-MOS, but also in an
EEPROM.
In the following it will be examined more in detail the four setup windows that can be accessed
selecting the first four menu items.
