BIOS settings (separate menus for STC2-AL and STC2-KL)

Enter BIOS: Press ESC or DEL when booting up; Hot keys: F1 Help, F8 Restore Last Time, F9 Load Default, F10 Save Exit. Modifying settings requires a restart, and incorrect settings can result in the inability to start. Both BIOS systems are divided into six top-level menus: Main, Advanced, Chipset, Security, Boot, Save&Exit.

1. Main (main interface)

Read only system information: BIOS version, CPU information, memory, card serial number, total runtime, power on times, startup reason; The system date and time can be modified.

2. Advanced (Advanced Settings, Core Configuration Area)

CPU Configuration: CPU status, SpeedStep, Turbo Turbo frequency, C-State energy-saving sleep settings;

Graphics Configuration: LVDS/EDP internal display, color depth, synchronization signal polarity, panel resolution selection;

Power Management: ACPI sleep mode, RTC timed power on, AT/ATX power simulation, real-time voltage and current monitoring;

System Management (SEMA): BMC hardware monitoring, CPU/board temperature and voltage monitoring, power on counting, error logging;

Watchdog: power on watchdog, runtime watchdog, timeout automatic reset system;

Super IO configuration: COM1 to COM4 serial ports, with separate settings for RS232/422/485 mode, IO address, and interrupts;

Serial Console redirection: supports VT100 and other terminals, configured with baud rate, verification, and flow control, used for debugging without a display;

Network Stack: UEFI network stack, IPv4/IPv6 PCIe network boot;

Trusted Computing security module: TPM1.2/TPM2.0 configuration, PCR hash library, clear TPM;

USB configuration: XHCI handover, storage driver, USB timeout, power on delay parameters.

3. Chipset chipset menu

STC2-AL: Northbridge (memory, TOLUD), non core display configuration (IGD display memory GTT/DVMT); South Bridge Cluster: HD Audio, PCIe, SATA, eMMC configuration;

4. Security Menu

Set administrator/user password, password length 3-20 characters, Secure Boot secure boot option.

5. Boot startup menu

Set the numeric keypad NumLock, Quiet Boot for silent boot, and Fast Boot for quick boot; The BBS boot priority of full UEFI and traditional BIOS (hard disk, NVMe, CD-ROM, USB, network PXE).

6. Save&Exit Save&Exit

Save/discard changes, restore factory defaults, save user-defined defaults, override temporary boot options, start EFI Shell.

Differences: The KL series has more options than AL, such as CSM compatibility support, VT-d virtualization IO pass through, RST storage mode, etc.

Driver and Application Installation (Windows 10 IoT Enterprise)

1. Mandatory installation sequence

Complete installation of Windows system;
