Watchdog
This option sets the timeout value for the POST watchdog.
POST Watchdog
Values: Disabled, 30sec, 1min, 2min, 5min, 10min, 30min
The watchdog is only active during the power-on-self-test of the system and provides a method to
prevent errors during boot up by performing a reset.
Stop Watchdog for User Interaction
Values: No, Yes
This option sets whether the POST watchdog should be stopped during setup, the popup of the
boot selection menu, or while waiting for setup password insertion.
Runtime Watchdog
Values: Disabled, One-time Trigger, Single Event, Repeated Event
This setting controls the operating mode of the runtime watchdog. This watchdog will be initialized
just before the operating system starts booting.

If the value is set to ‘One-time Trigger’, the watchdog is disabled after the first trigger.

If the value is set to ‘Single Event’, every stage will be executed only once, and then the
watchdog will be disabled.

If the value is set to ‘Repeated Event’, the last stage will be executed repeatedly until a
reset occurs.
Delay
Values: Disabled, 10sec, 30sec, 1min, 2min, 5min, 10min, 30min
Sets the delay time before the runtime watchdog becomes active. This ensures that an operating
system has enough time to load.
Event 1
Values: ACPI Event, Reset, Power Button
Event options control the event that is generated when timeout 1 is reached.
Event 2
Values: Disabled, ACPI Event, Reset, Power Button
Event options control the event that is generated when timeout 2 is reached.
EPU-3311 BIOS Reference Manual

Advanced Menu
Event 3
Values: Disabled, ACPI Event, Reset, Power Button
Event options control the event that is generated when timeout 3 is reached.
Timeout 1
Values: 1sec, 2sec, 5sec, 10sec, 30sec, 1min, 2min, 5min, 10min, 30min
These options adjust the timeout value a first stage watchdog event.
Timeout 2
Values: 1sec, 2sec, 5sec, 10sec, 30sec, 1min, 2min, 5min, 10min, 30min
These options adjust the timeout value a second stage watchdog event.
Timeout 3
Values: 1sec, 2sec, 5sec, 10sec, 30sec, 1min, 2min, 5min, 10min, 30min
These options adjust the timeout value a third stage watchdog event.
Watchdog ACPI Event
Values: Shutdown, Restart
These options allow an orderly operating system shutdown or restart.
Note: In ACPI mode, it is not possible for a “Watchdog ACPI Event” handler to directly restart or
shutdown the OS. For this reason, the BIOS will do one of the following:

For Shutdown: An over temperature notification is executed. This causes the OS to shut
down in an orderly fashion.

For Restart: An ACPI fatal error is reported to the OS.

Boot Display Device
Values: VBIOs Default
Active LFP
Values: No LVDS, LVDS
Active LFP sets the active local flat panel configuration.
Always Try Auto Panel Detect
Values: No, Yes
‘Yes’ prompts the BIOS to look for an EDID data set in external EEPROM in order to configure the
Local Flat Panel. If no external EDID data set exists, the data set selected under ‘Local Flat Panel
Type’ is the default fallback data set.
Local Flat Panel Type
Values: VGA 640x480 1x18 (002h), VGA 640x480 1x18 (013h), WVGA 800x480 1x24 , 1Bh),
SVGA 800x600 1x18 (01Ah), XGA 1024x768 1x18 (006h), XGA 1024x768 1x24 (008h), WXGA
1280x800 1x18 (01Eh), WXGA 1280x768 1x24 (01Ch), Customized EDID* 1, Customized EDID*
2, Customized EDID* 3
These values set a predefined LFP type. The Auto option allows the BIOS to automatically detect
and configure the attached LVDS panel. Auto detection is performed by reading an EDID data set
via the video I²C bus. The number in brackets specifies the internal number of the respective
panel data set.
Backlight Inverter Type
Values: None, PWM, I2C
These options set the type of backlight inverter used.
PWM = Uses the IGD PWM signal.

I2C = Will use the I C backlight inverter device connected to the video I C bus.
Digital Display Interface 1
Values: Disabled, DisplayPort, HDMI/DVI, Auto
This option controls output of the Digital Display Interface 1.
PWM Inverter Frequency (Hz)
Values: 200 – 4000
The option adjusts the PWM inverter frequency in Hz. It is only visible if 'Backlight Inverter Type' is
'PWM'.

Values: PWM Normal, PWM Inverted
This option sets the PWM inverter polarity. It is only visible if 'Backlight Inverter Type' is 'PWM'.
Backlight Setting
Values: 0%, 10%, 25%, 40%, 50%, 60%, 75%, 90%, 100%
Backlight Setting controls the backlight value in percent of the maximum setting.
Force LVDS Backlight
Values: No, Yes
This will force LVDS Enable and LVDS VDD Signals unconditionally.
Inhibit Backlight
Values: No, Permanent, Until End Of POST
These values control the backlight on signal activation when the panel is activated or inhibited.
Options include no inhibition, inhibition at the end of BIOS POST or permanent inhibition.
LVDS SSC
Values: Disabled, 0.5%, 1.0%, 1.5%, 2.0%, 2.5%
The options adjust the depth LVDS Spread Spectrum Clock modulation.
