System BIOS
5.1 BIOS SETUP
When the power of the Server is turned on, POST is executed to display a full screen logo (default
BIOS SETUP settings). If an error is detected during the execution of POST, the test execution
screen appears instead to indicate the error.
The screen switching can be modified by the ESC key or the setting of BIOS SETUP.
To change the setting, press the <F2> key during the execution of POST to boot BIOS SETUP and
select the menu item to be changed in the menu by using arrow keys appropriately. Refer to the
User's Guide of the Server for details of BIOS SETUP.
For POST error messages and the consequent actions to take, see Chapter 8.
5.2 Duplication of System BIOS
The system BIOS of the Server is duplicated to allow two BIOSs to be operated, which are called
primary BIOS and secondary BIOS.
In the normal operation, the primary BIOS is booted to operate the system. At the occurrence of a
data error in the primary BIOS or a fault of the device in which the system BIOS is stored, the
secondary BIOS is booted as soon as possible to operate the system. This operation can avoid
system shutdown caused by a malfunction of the system BIOS.
Both the primary and secondary BIOSs installed in the Server at the shipment are the system BIOS
of the latest version. Each system BIOS update makes the secondary BIOS updated to be the
primary BIOS.
Then the switched primary BIOS is booted to operate the system.
For the actions taken at the occurrence of a data error in the primary BIOS or a fault of the device
in which the system BIOS is stored, see Chapter 8.
