5.8.1.1 Dual Monitor Video
The BIOS supports single and dual video on the S2600 family of Server Board when add-in video adapters
are installed. Although there is no enable/disable option in BIOS screen for Dual Video, it works when both
"Onboard video" and "Add-in Video Adapter" are enabled.
In the single video mode, the onboard video controller or the add-in video adapter is detected during the
POST. In the dual video mode, the onboard video controller is enabled and is the primary video device while
the add-in video adapter is allocated resources and is considered the secondary video device.
5.8.1.2 Configuration Cases – Multi-CPU Socket Boards and Add-In Video Adapters
Because this combination of CPU Socket and PCIe* topology is complicated and somewhat confusing, the
following set of "Configuration Cases" was generated to clarify the design.
When there are no add-in video cards installed...
•
Case 1: Onboard Video only active display.
Onboard Video = Enabled (grayout, can't change)
Legacy VGA Socket = CPU Socket 1 (grayout, can't change)
Add-in Video Adapter = Disabled (grayout, can't change)
When there is one add-in video card connected to CPU Socket 1...
•
Case 2: Onboard video active display, add-in video doesn't display.
Onboard Video = Enabled
Legacy VGA Socket = CPU Socket 1 (grayout, can't change)
Add-in Video Adapter = Disabled
Case 3: Add-in video active display, onboard video doesn't display.
Onboard Video = Disabled,
Legacy VGA Socket = CPU Socket 1 (grayout, can't change)
Add-in Video Adapter = Enabled
Case 4: Both onboard video and add-in video are active displays. But only onboard could be the
active display during BIOS POST (Dual Monitor).
Onboard Video = Enabled
Legacy VGA Socket = CPU Socket 1 (grayout, can't change)
Add-in Video Adapter = Enabled
• When there is one add-in video card connected to CPU Socket 2...
Case 5: Onboard video active display, add-in doesn't display.
Onboard Video = Enabled
Legacy VGA Socket = CPU Socket 1
Add-in Video Adapter = Disabled (grayout, can't change)
Case 6: Add-in video active display, onboard video doesn't display.
Onboard Video = Disabled (grayout, can't change)
Legacy VGA Socket = CPU Socket 2
Add-in Video Adapter = Enabled (grayout, can't change)
When there are add-in video cards connected to both CPU Socket 1 & 2...
•
Case 7: Onboard video active display, add-in video on Socket 1 and Add-in video on Socket 2 don't
actively display.
Onboard Video = Enabled
