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.
System information contains the following 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: TBD
- Maximum Read Request: TBD
- ASPM Support: TBD
- Extended Synch: TBD
- Link Training Retry: TBD
- Link Training Timeout (uS): TBD
- Restore PCIE Registers: TBD
Power Settings
- 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.
