Overview

  • See what is BIOS
  • fitlet BIOS is based on American Megatrends Inc. (AMI) BIOS.
  • BIOS can be accessed by pressing Del during power up cycle.

BIOS Menu

Main

The screen provides date, time and boot features settings, as well as basic system information:

  • BIOS Vendor: American Megatrends
  • Core Version: 4.6.5.4
  • Compliancy: UEFI 2.3.1; PI 1.2
  • BIOS Version: SBCFLT_0.08.02_7
  • Build Date and Time: MM/DD/YYYY HH:MM:SS
  • System Date: HH:MM:SS
  • System Time: Weekday MM/DD/YYYY
  • Access Level: Administrator

Advanced

The section provides advanced system features and functionality settings.
Warning: Setting items in this section to incorrect values may cause system to malfunction.

PCI Settings

PCI, PCI-X and PCI Express settings:

  • PCI Latency Timer: Value to be programmed into PCI latency timer register.
  • VGA Palette Snoop: Enables or Disables VGA palette registers snooping.
  • PERR# Generation: Enables or Disables PCI device to generate PERR#.
  • SERR# Generation: Enables or Disables PCI device to generate SERR#.
  • Relaxed Ordering: Enables or Disables PCI Express device relaxed ordering.
  • Extended Tag: If enabled allows device to use 8-bit tag field as a requester.
  • No Snoop: Enables or Disables PCI Express device no snoop option.
  • Maximum Payload: Set maximum payload of PCI Express device or allow system BIOS to select the value automatically.
  • Maximum Read Request: Set maximum read request size of PCI Express device or allow system BIOS to select the value automatically.
  • ASPM Support: Set the ASPM (Active State Power Management) level:
    • Force L0s - force all links to L0s state
    • Auto - BIOS auto configure
    • Disable - disables ASPM
  • Extended Synch: If enabled allows generation of extended synchronization patterns.
  • Link Training Retry: Defines number of retry attempts SW will take to retrain the link if previous attempt was unsuccessful.
  • Link Training Timeout (uS): Defines number of microseconds SW will wait before polling "Link Training" bit in link status register. Value range 10-10000 us.
  • Restore PCIE Registers: On non-PCI Express aware OS's (Pre Windows Vista) some devices may not be correctly reinitialized after S3 (sleep state). Enabling this restores PCI Express device configurations on S3 resume. Warning: Enabling this may cause issues with other HW after S3 resume.

Power Settings

System ACPI and power management policy parameters:

  • ACPI Auto Configuration: Enables or Disables BIOS ACPI (power management policy) auto configuration.
  • Hibernation State: Enables or Disables system ability to Hibernate (S4). This option may be not effective with some OS.
  • Sleep State: Select ACPI sleep state the system will enter when Suspend/Power button is pressed.
  • Lock Legacy Resources: Enables or Disables lock of legacy resources.
  • Restore on AC Power Loss: Set the way fitlet is turned-on after power failure/interruption occurred or the moment power cable is plugged. The available options are:
    • Power On - system powers on automatically
    • Power Off - system remains off
    • Last State - based on system state before the failure it will be either On or Off
    • Disable - the feature is disabled
  • APU TDP: Set processor maximum power consumption (thermal design power). Enter values between 1-25000 [mW], when default value is 4500 [mW]. Higher value means better performance, and hence higher temperature.

TPM Settings

Trusted platform module settings:

  • Security Device Support: Enables or Disables BIOS support for security device. OS will not show security device. TCG EFI protocol and INT1A interface will not be available.

CPU Settings

CPU configuration parameters:

  • PSS Support: Enable or Disable the generation of ACPI _PPC, _PPS and _PCT objects.
  • PSTATE Adjustment: Provide to adjust start-up P-state level.
  • NX Mode: Enable or Disable non-execute page protection function.
  • SVM Mode: Enable or Disable CPU virtualization.
  • C6 Mode: Enable or Disable C6 state.
  • CPB Mode: Auto or Disable core performance boost.
  • Core Leveling Mode: Change the number of Cores in the system.

Video Settings

  • Integrated Graphics: Enable or Disable integrated graphics controller.
  • UMA Frame Buffer Size: Set frame buffer size (32MB-2GB).
  • Remote Display Feature: Enable or Disable remote display feature support.
  • HDMI Audio: Enable or Disable Gnb HD audio support.
  • IOMMU: Enable or Disable IOMMU support.
  • PSPP Policy: Configure PCI Express speed power policy:
    • Disabled
    • Performance
    • Balanced-High
    • Balanced-Low
    • Power saving

  • SDIO Access Mode: Set SD device access mode:
    • Auto - Access SD device in DMA mode if controller support it, otherwise in PIO mode.
