9.5.2 Boot Settings Configuration
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
AddOn 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
Specifies 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
1. The term 'AC power loss' stands for the state when the module looses the standby
voltage on the 5V_SB pins. On congatec 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.
2. Inexpensive ATX power supplies often have problems with short AC power sags.
When using these ATX power supplies it is possible that the system turns off but
does not switch back on, even when the PS_ON# 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.
3. Unlike other module designs available in the embedded market, a CMOS battery is
not required by congatec modules to support the 'Power Loss Control' feature.
