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

SD/SDIO configuration parameters:
- SDIO Access Mode: Set SD device access mode:
- Auto - Access SD device in DMA mode if controller support it, otherwise in PIO mode.
- DMA - Access SD device in DMA mode.
- PIO - Access SD device in PIO (programmed input/output) mode.
- Mass Storage Device Emulation Type: TBD
