Table 4. Device and I/O ports details
Item
Options
Description
Active Video
• Onboard Device
• Add-in Device
This setting only applies 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 chooses to display its graphical desktop.
PCI 64-Bit Resource Allocation
• Enable
• Disable
• Auto
[Enable] or [Disable] the allocation of 64-bit resources for
PCI. Auto is the default setting, would allocate some
resources below 4GB for legacy compatibility.
MM Config Base
• 3GB
• 2GB
• 1GB
Recommend default setting of 3GB. A higher value will
increase memory available to the OS below 4G but
reduce memory mapped I/O (MMIO) resource available to
PCI adapters. A lower than 3GB value will increase MMIO
resources but decrease memory available to OS below
4GB. Revert to your previous selection if you see new
issues with changed setting.
