Information:
The following diagrams, BIOS menu items and their descriptions refer to BIOS version 1.00. It is there-
fore possible that these diagrams and BIOS descriptions do not correspond with the installed BIOS
version.
1.1 General information
BIOS stands for "Basic Input Output System". It is the most basic standardized communication between the user
and the system (hardware). The BIOS system used in this B&R industrial PC is produced by Insyde.
The BIOS Setup Utility lets you modify basic system configuration settings. These settings are stored in CMOS
and in EEPROM (as a backup).
The CMOS data is buffered by a battery (if present), and remains in the B&R industrial PC even when the power
is turned off (no 24 VDC supply).
1.2 BIOS setup and boot procedure
BIOS is immediately activated when switching on the power supply of the B&R industrial PC or pressing the power
button. The system checks if the setup data from the EEPROM is "OK". If the data is "OK", then it is transferred to
the CMOS. If the data is "not OK", then the CMOS data is checked for validity. An error message is output if the
CMOS data contains errors and the boot procedure can be continued by pressing the <F1> key. To prevent the error
message from appearing at each restart, open the BIOS setup by pressing the <Del> key and re-save the settings.
BIOS reads the system configuration information in CMOS RAM, checks the system, and configures it using the
Power On Self Test (POST).
When these "preliminaries" are finished, BIOS seeks an operating system in the data storage devices available
(hard drive, floppy drive, etc.). BIOS launches the operating system and hands over control of system operations
to it.
To enter BIOS Setup, the <F2> key must be pressed after the USB controller has been initialized as soon as the
following message appears on the monitor (during POST): "Press F2 to go to Setup Utility"
Information:
The POST screen is only displayed for a fraction of a second due to optimized boot procedures. It is
however, still possible to enter BIOS.
