ASUS P9D WS - Howto Disable PCIe to PCI Bridge via BIOS Mod?

[silverstone777]

I’m attempting to disable the ASM1083/ASM1085 PCIe to PCI Bridge on my ASUS P9D WS Motherboard via BIOS Mod on a NAS System running Debian Linux. Yes, I know this is Win-Raid, but I think it’s one of the biggest BIOS Mod Community out there, so I hope that you can help me nevertheless.

This seems to be needed because in Linux the ASPM Support is disabled as soon as this Controller is detected.

@Darkestnoir did something similar in another Thread for another ASUS Motherboard → [Request] ASUS Prime B360M-C option to disable PCIe root ports

Following Step-by-Step the Instructions on GitHub - datasone/setup_var.efi: UEFI command-line tool for read/write access of variables, I exported the “Setup” String/Folder as Body from UEFITool.

However when attempting to open it using ifrextractor, I just get “No IFR data found”.

Did this occur to somebody else ? If so, how did you manage to get it fixed ?

Thank you for your Help

Did you face a Similar Issue ?

Thank you for your Reply. So it’s not the “Setup” that I need to export, just the “MiniSetupResourceSection” ?

It’s “something” “around there”
