Server stuck on "pei--ipmi initiatilizing 19" after installing NIC

[bcs23pharm]

Hi all,
I'm attempting to install a new nic (intel x550-t1) in my supermicro x11ssh-ln4f unraid server. mobo is on latest bios. server has been working flawlessly up to this point. After installing the nic, server hangs at "pei--ipmi initializing" with a code 19 then reboots. removing the nic the server will then boot just fine, no issue. The card itself was tested in a windows pc and works fine. i understand code 19 is a pre-memory South Bridge initialization error but im not sure what to do with that information. I attempted to change the pci slot oprom to EFI from Legacy and this had no effect. I'm at a loss for how to proceed and hoping someone with more technical expertise can assist. thanks

Try disabling "Interrupt 19 Capture" in the BIOS. I think on Supermicro it's here: Advanced->Boot Feature->Interrupt 19 Capture

This will disable the ability for PCIe cards to interrupt the POST. This might affect legacy PXE and SAN/HBA booting.

Maybe also try updating the card's firmware if that's possible.
