ItemOptionsDescription
Onboard SATA Mode
  • AHCI

  • RAID

Configure SATA as AHCI or RAID.
Note
This item is platform-dependent.
Onboard sSATA Mode
  • AHCI

  • RAID

Configure sSATA as AHCI or RAID.
Note
This item is platform-dependent.
Active Video
  • Onboard Device

  • Add-in Device

This item is available only when the server has an add-in video adapter. When the option ROM is set to [Legacy] for both onboard and add-in video adapters, the Active Video setting controls which single adapter will display the System Setup utility. Onboard Device is the default setting.

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 OS displays its graphical desktop.

PCI 64-Bit Resource Allocation
  • Enabled

  • Disabled

  • Auto

Enable/Disable the allocation of 64-bit resources for PCI. Auto is the default setting. [Auto] mode allocates some resources below 4 GB for legacy compatibility.

MM Config Base
  • 3GB

  • 2GB

  • 1GB

Recommend the default setting: 3GB. A greater value increases memory available to the OS (below 4 GB) and reduces the memory mapped I/O (MMIO) resource available to PCI adapters. Values smaller than 3 GB increases MMIO resources but reduces memory available to OS (below 4 GB). Revert to your previous selection if new issues occur with setting change.
Intel® VT for Direct I/O (VT-d)
  • Enabled

  • Disabled

Enable/Disable Intel® Virtualization Technology for Directed I/O (VT-d) by reporting the I/O device assignment to VMM through DMAR (DMA Remapping) ACPI Tables. Enabled is the default setting.
