PCIe/PCI/PnP Configuration Menu

Above 4G Decoding

This setting enables 64-bit PCI device access to memory beyond 4 GB for improved memory utilization and performance. The options are Disabled and Enabled.

Re-Size BAR Support

This setting enables or disables the Re-Size Base Address Register feature for compatible PCIe devices, which allows the system to allocate more memory to the device. The options are Disabled and Enabled.

SR-IOV Support

This setting enables or disables Single Root I/O Virtualization support for the system's PCIe devices. The options are Disabled and Enabled.

BME DMA Mitigation

This setting enables or disables Bus Mastering Error (BME) Direct Memory Access (DMA) mitigation for protection during the pre-boot process. The options are Disabled and Enabled.

PCIe ARI Support

This setting enables alternative routing- ID interpretation. The options are Disabled, Enabled, and Auto.

PCIe ARI Enumeration

This setting controls the forwarding of Alternate Routing-ID Interpretation (ARI) information for each downstream port, which is essential for device identification in PCIe systems. The options are Disabled, Enabled, and Auto.

Relaxed Ordering

This setting determines whether PCI Express devices are permitted to bypass strict transaction ordering, which can lead to potential performance improvements. The options are Disabled and Enabled.

Clock Spread Spectrum

This setting allows the BIOS to monitor and reduce the level of Electromagnetic Interference (EMI) generated by system components. The options are Disabled and Enabled.

No Snoop

This setting configures the No Snoop option for PCI Express devices, determining whether memory accesses bypass the cache. The options are Disabled and Enabled.

VGA Priority

This setting allows you to choose the primary video output source for the system. The options are Onboard and External.

PCIe Ten Bit Tag Support

This setting enables the use of ten-bit tags for PCIe devices, which can improve data handling and management. The options are Disabled, Enabled, and Auto.

NVMe Firmware Source

This setting determines the source of firmware for NVMe devices, allowing you to select between native support or vendor-specific firmware. The options are Vendor Defined Firmware and AMI Native Support.

PCI Devices Option ROM Setting

CPU SLOT3-10 PCIe 5.0 x16 OPROM

This setting enables or disables the Option ROM for the SLOT3 PCIe 5.0 x16 interface. The options are Disabled and EFI.

M.2-C1 OPROM

This setting enables or disables the Option ROM for the M.2-C1 slot. The options are Disabled and EFI.

M.2-C2 OPROM

This setting enables or disables the Option ROM for the M.2-C2 slot. The options are Disabled and EFI.

Onboard Video Option ROM

This setting selects the type of firmware to be loaded for onboard video. The options are Disabled and EFI.

AOM-PTG-I2T OPROM

This setting allows you to select the firmware function to be loaded for the onboard LAN1 interface. The options are Disabled and EFI.
