Corrupted vBIOS? The PCI BAR assignment for the processed device is invalid.

[snaiperist]

Hello everyone,

I was attempting to replace the vBIOS of a Lenovo Legion 9i when nvflashk displayed the message "Memory integrity is enabled and may interfere with some operations. Press Y to continue." Instead of pressing Y (or N, or closing nvflashk), I opened Settings to disable Memory integrity and then restarted the computer.

Now, GPU-Z recognizes the RTX 4090, but the "BIOS Version" field is blank. I reopened nvflashk and tried to flash it with the original vBIOS, but now it gives me the following message:
"The PCI BAR assignment for the processed device is invalid. Please check the NVIDIA website for possible SBIOS Setup settings to match the processed device," and then the window closes.

Could someone help me?

Oh wow. What a mess. I sure hope your vga BIOS is not a part of laptop motherboard BIOS. Go to device manager and disable the RTX 4090 L. and then try flashing if you're doing it in live install.

Thank God - I went to Device Manager and the RTX 4090 was already disabled. I just had to enable it and then flash it with its original vBIOS. Thank you very much, pavle!

Wow! I'm so glad you've managed to fix it, now please, don't flash it again, I'm sure that laptop wasn't cheap.
