Boot Settings Conguration9.5.2
Feature Options Description
Quick Boot Disabled
Enabled
If Enabled, some POST tasks will be skipped to speed-up the BIOS boot process.
Quiet Boot Disabled
Enabled
Disabled displays normal POST diagnostic messages. Enabled displays OEM logo instead of POST messages.
Note: The default OEM logo is a dark screen.
Boot Display Clear
Maintain
Controls the end of POST boot display handling, if Quiet Boot is enabled. If set to Maintain the BIOS will maintain the current
display contents and graphics video mode used for POST display. If set to Clear the BIOS will clear the screen and switch to
VGA text mode at end of POST.
Automatic Boot List Retry Disabled
Enabled
Add-On ROM Display Mode Force BIOS
Keep current
Set display mode for Option ROM.
Halt On Error Disabled
Enabled
Determines whether the BIOS halts and displays an error message if an error occurs. If set to Enabled the BIOS waits for user
input.
Hit ‘DEL’ Message Display Disabled
Enabled
Allows/Prevents the BIOS to display the ‘Hit Del to enter Setup’ message.
Interrupt 19 Capture Disabled
Enabled
Allows/Prevents the option ROMs (such as network controllers) from trapping the boot strap interrupt 19.
PXE Boot to LAN Disabled
Enabled
Disable/Enable PXE boot to LAN
Note: When set to ‘Enabled’, the system has to be rebooted in order for the Intel Boot Agent device to be available in the Boot
Device Menu.
Power Loss Control (see
note below)
Remain Off
Turn On
Last State
Species the mode of operation if an AC power loss occurs.
Remain Off keeps the power off until the power button is pressed.
Turn On restores power to the computer.
Last State restores the previous power state before power loss occurred.
Note: Only works with an ATX type power supply.
Note
The term ‘AC power loss’ stands for the state when the module looses the standby voltage on the ‘VCC_5V_SBY’ pins. On congatec 1.
modules, the standby voltage is continuously monitored after the system is turned off. If after 30 seconds the standby voltage is no longer
detected, then this is considered an AC power loss condition. If the standby voltage remains stable for 30 seconds, then it is assumed that
the system was switched off properly.
Inexpensive ATX power supplies often have problems with short AC power sags. When using these ATX power supplies it is possible that 2.
the system turns off but does not switch back on, even when the PS_ON# (or SUS_S3) signal is asserted correctly by the module. In this
case, the internal circuitry of the ATX power supply has become confused. Usually another AC power off/on cycle is necessary to recover
from this situation.
Unlike other module designs available in the embedded market, a CMOS battery is not required by congatec modules to support the 3.
‘Power Loss Control’ feature.
