== Overview ==Basic Input/Output System ([[fitlet BIOS) standard defines firmware interface. The fundamental purposes of BIOS is to initialize, test system hardware, and load a bootloader or operating system from mass memory. BIOS also provides an abstraction layer for hardware, a consistent way for application programs and operating systems to interact with the keyboard, display, and other input/output devices. * BIOS code stored in non-volatile SNOR flash memory and accessed during power up phase.* BIOS technology is in transitional process toward the Unified Extensible Firmware Interface (UEFI) since 2010. UEFI is a specification that defines a software interface between an operating system and platform firmware. UEFI images provide legacy support for BIOS services.* BIOS vendor is American Megatrends Inc. (AMI).* BIOS can be accessed by pressing ''Del'' during power up phase. == BIOS Menu ===== Main ===The screen provides date, time and boot features settings, as well as basic system information. === Advanced ===Advanced screen contains most of system features and functionality configurations.Warning: Setting items on this screen to incorrect values may cause the system to malfunction. === PCI Settings === PCI Latency Timer: TBD VGA Palette Snoop: TBD PERR# Generation: TBD SERR# Generation: TBD Relaxed Ordering: TBD Extended Tag: TBD No Snoop: TBD 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 ==== A ======== B ======== C ======== D ======== E ==== 2.2.2 Power Settings ACPI Auto Configuration: TBD Hibernation State: TBD Sleep State: TBD Lock Legacy Resources: TBD Restore on AC Power Loss: TBD APU TDP: TBD 2.2.3 TPM Settings Security Device Support: TBD 2.2.4 CPU Settings PSS Support: TBD PSTATE Adjustment: TBD NX Mode: TBD SVM Mode: TBD C6 Mode: TBD CPB Mode: TBD Core Leveling Mode: TBD 2.2.5 Video Settings Integrated Graphics: TBD UMA Frame Buffer Size: TBD Remote Display Feature: TBD HDMI Audio: TBD IOMMU: TBD PSPP Policy: TBD 2.2.6 SATA Settings OnChip SATA Channel: TBD OnChip SATA Type: TBD OnChip IDE Mode: TBD SATA IDE Combined Mode: TBD 2.2.7 Memory Settings Memory Clock: TBD Memory Clear: TBD 2.2.7.1 Memory Configuration Memory Hole Remapping: TBD Bank Interleaving: TBD Memory Hole 15MB – 16MB: TBD 2.2.7.2 Socket Information 2.2.8 SDIO Settings SDIO Access Mode: TBD Mass Storage Device Emulation Type: TBD 2.2.9 USB Settings Legacy USB Support: TBD XHCI Hand-off: TBD EHCI Hand-off: TBD USB Mass Storage Driver Support: TBD Port 60/64 Emulation: TBD USB transfer timeout: TBD Device reset timeout: TBD Device power-up delay: TBD === Boot ===TBD Setup Prompt Timeout: TBD Bootup Numlock State: TBD Quiet Boot: TBD Fast Boot: TBD SATA Support : TBD VGA Support: TBD USB Support: TBD PS2 Device Support: TBD Network Stack Driver Support: TBD UEFI Boot: TBD Boot Mode Select: TBD Fixed Boot Order Priorities: TBD 2.3.1 CSM16 ParametersTBD GateA20 Active: TBD Option ROM Messages: TBD INT19 Trap Response: TBD 2.3.2 CSM ParametersTBD Launch CSM: TBD Boot option filter: TBD Launch PXE OpROM policy: TBD Launch Storage OpROM policy: TBD Launch Video OpROM policy: TBD Other PCI device ROM priority: TBD 2.3.3 USB Key Drive BBS PrioritiesTBD === Security ===TBD Administrator Password: TBD User Password: TBD 2.4.1 Secure Boot MenuTBD Secure Boot: TBD Secure Boot Mode: TBD Key Management: TBD === Save & Exit ===The exit screen provides options to save or discard changes before exiting BIOS.guide]]
