| Item | Options | Description |
|---|---|---|
| Onboard SATA Mode |
| Configures SATA as ACHI or RAID. |
| Onboard SATA 1 Mode |
| Configures SATA 1 as ACHI or RAID. |
| Onboard SATA 2 Mode |
| Configures SATA 2 as ACHI or RAID. |
| Onboard SATA 3 Mode |
| Configures SATA 3 as ACHI or RAID. |
| Active Video |
| This feature is available only when the server has an add-in video adapter. When option ROM is set to [Legacy] for both onboard and add-in video adapters, the setting controls which single adapter displays the System Setup utility. Regardless of this setting, the system boot early video is displayed at the onboard video only, and the management controller remote console shows the onboard video only. This setting does not affect how the operating system (OS) displays its graphical desktop. |
| PCI 64-Bit Resource Allocation |
| Enables or disables allocation of 64-bit resources for PCI devices. [Auto]: Allocates some resources below 4GB for legacy compatibility. |
| MM Config Base |
| [Auto]: The system assigns the value automatically. A higher value increases memory available to the operating system below 4GB, but reduces memory mapped I/O (MMIO) resource available to PCI adapters. A lower value increases MMIO resources but decreases memory available to the operating system below 4GB. If there is any issue occurred after changing the setting, you can revert to the previous selection. |
| Intel® VT for Direct I/O (VT-d) |
| Enables or disables Intel® Virtualization Technology for Directed I/O (VT-d) by reporting the I/O device assignment to VMM (Virtual Machine Monitor) through DMAR (DMA Remapping) ACPI (Advance Configuration Power Interface) tables. |
| DMA Control Opt-In Flag |
| Enables or disables DMA_CTRL_PLATFORM_OPT_IN_FLAG in DMAR ACPI table. This feature is not compatible with Direct Device Assignment (DDA). |
| SRIOV |
| Enables or disables support of resource allocation for Single Root I/O Virtualization (SR-IOV) virtual functions during system boot. |
| Enable/Disable Onboard Device(s) | N/A | Enables or disables onboard devices or slots. |
| Enable/Disable Adapter Option ROM Support | N/A | Controls Legacy and UEFI-compliant adapter support. Disabling UEFI/Legacy support may adversely affect pre-boot/boot functions. |
| Set Option ROM Execution Order | N/A | Sets load order for Legacy Option ROMs. |
| PCIe Gen Speed Selection | N/A | Chooses generation speed for available PCIe slots. |
| Override Slot Bifurcation | N/A | Overrides bifurcation of the physical x16 slot to support the adapter with multiple devices. |
| Console Redirection Settings | N/A | Configures console redirection and COM port settings. |
| USB Configuration | N/A | Enables or disables USB storage devices or individual ports. |
| Intel® VMD technology | N/A | You can press Enter to open Intel® VMD for Volume Management Device Configuration menu. |
