Option ROM execution strategy: UEFI or Legacy can be selected for network, storage, video, and other PCI devices respectively.
5.10 USB Configuration (Advanced → USB Configuration)
Legacy USB Support: It is recommended to enable the USB keyboard/mouse for use during DOS or BIOS phases.
XHCI Hand Off: If the operating system does not support XHCI, it needs to be enabled (usually left as default).
USB Mass Storage Driver Support: When enabled, it can recognize USB drives in the BIOS.
5.11 Chipset Menu
5.11.1 System Agent Configuration
Graphics Configuration:
Primary Display: Optional Auto/IGFX/PEG/PCI, deciding to prioritize the use of integrated graphics cards, PCIe graphics cards, or PCI graphics cards during startup.
Internal Graphics:Auto/Enable/Disable, If installing a dedicated graphics card, it can be set to Disable to free up memory, but if multi screen output is required, keep it enabled.
DVMT Pre Located: It is recommended to allocate at least 64MB of video memory for integrated graphics.
DVMT Total Gfx Mem: Maximum available video memory, optional 256M/128M/MAX.
PEG Port Configuration: Set the link speed (Auto/Gen1/Gen2/Gen3) and detect non compatible devices for PCIe x16 slots.
5.11.2 PCH-IO Configuration
PCI Express Configuration:
LAN1/LAN2 Controller: can independently enable or disable dual network cards, and can enable the PCIe Option ROM.
Wake on Lan: If network wake-up is required, set it to Enabled.
Restore AC Power Loss: Behavior after power failure recovery - [Power On] automatically turns on, [Power Off] remains turned off, [Last State] restores the state before power failure. Power On is commonly used in industrial sites.
GPIO Group Control: Each GPIO pin can be individually set to input or output high/low (through GPIO 1 Control~GPIO 32 Control) to facilitate the initialization of IO status during system startup.
SATA Configuration:
SATA Controller(s):Enabled。
SATA Mode: Optional AHCI (recommended) or Intel RST Premium (supports RAID).
SATA Controller Speed: Default (auto negotiate Gen3), can also force Gen1/Gen2 to be compatible with older hard drives.
Each port can be individually enabled/disabled and display information about connected devices.
USB Configuration:
XHCI Disable Compliance Mode: Generally remains False.
USB Port Disable Override: Specific physical ports (HS/SS) can be disabled for secure isolation.
HD Audio Configuration: Control the audio controller to enable/disable.
Serial IO Configuration: This board supports I2C0 and GPIO controllers, and can enable/disable and set I2C voltage (1.8V/3.3V) and clock speed (for onboard I2C bus).
5.12 Security Menu
Administrator/user password can be set and Secure Boot can be enabled (CSM needs to be turned off).
5.13 Boot Menu
Boot mode select:LEGACY/UEFI, Affects the type of startup device.
Fixed Boot Order Priorities: Priority order can be set by device type (hard drive, optical drive, USB, network).
Supports EFI Shell startup.
5.14 Save and Exit
Provide functions such as saving/discarding changes, restoring default values, and boot overwrite (such as booting from a USB drive).

System resource and interrupt allocation
6.1 Memory Mapping
The traditional ISA area (15MB~16MB) is reserved, the high BIOS area is located at the top of 4GB, and the APIC configuration space is in FEC00000~FECFFFFF, etc.
6.2 I/O Address
COM1~COM6 occupy standard address (3F8/2F8/3E8/2E8/2E0/3E0) and IRQ (4/3/5/6/10/11) respectively, which can be adjusted by the user in BIOS.
LPT1 defaults to 378h/IRQ7.
SATA controller occupies F080h, SMBus address E000h, etc.
6.3 IRQ Allocation (APIC Mode)
Interruptions 16-19 are shared by PCIe root ports, HD Audio, SATA, etc., as detailed in Table 8 of the manual. When installing a PCI card, if there is a resource conflict, you can try changing the PCI slot because the interrupt routing for different slots is different.
6.4 PCI Configuration Space and Routing
Built in devices such as graphics cards, USB xHCI, SATA controllers, dual network cards, etc. all have fixed bus/device numbers. The PCIe to PCI bridge (ITE8892) connects the PCI slot, and interrupts in the PCI slot can be adjusted through BIOS (if available).
6.5 SMBus Address
The SPDs of DIMM A/B respond to A0h and A4h respectively, and can be used for memory information reading.
Driver installation and operating system support
Official support for Windows 7 (only 6th generation) CPU)、Windows 8.1 64-bit、Windows 10 64-bit、OpenSUSE Leap 42.1、Fedora 25、Ubuntu 16.04 LTS 64-bit。 Drivers can be downloaded from the official website product page, including chipset, graphics card (integrated HD Graphics), network card (I219-LM/I211-AT), audio (ALC892), SATA (Intel RST), GPIO, etc.
Installation points:
For Windows 7, as the H110 chipset does not natively support USB 3.0, it is necessary to inject USB 3.0 drivers into the installation image or use a PS/2 keyboard and mouse.
If using Intel RST RAID mode, the F6 driver needs to be loaded during installation (a USB flash drive can be used).
GPIO and serial communication may require the installation of the Super IO driver (NCT6106D) to use advanced features.
Common troubleshooting
Fault 1: No display when powered on, fan turning
