S1200BTL option rom control greyed out

[AHenr2]

Hi all,

I'm assembling a new system based on a S1200BTL board. It's inside a Supermicro chassis.

I need to deactivate the oprom of a specific PCIe card, but the option rom control in "advanced/PCI Configuration/PCI port Oprom Control" are all greyed out.

What am i missing?

thank you

Hello,

To answer your question, the PCI port Oprom is grayed out by default reason why those settings cannot be changed.
