Re: Help unlock HP 830 g9

Thank you. It worked

Ah yes, this that stupid Audio Calibration data thing on some newer models. You can't edit it via the BIOS menus like the feature byte etc, only that UEFI proprietary tool that HP uses internally where you can calibrate it.

But alternatively you can edit more CMOS string values manually using a USB EFI shell with the "UefiBiosConfig.efi" tool.

If it's similar to va "HP EliteBook 860 16 inch G9 Notebook PC" you can try my personal dumped calibration data for the audio chip. (Hope it doesn't screw it up)

Anyway make a bootable USB EFI Shell, extract the zip into the root of the USB. Navigate to EFI\Boot and copy my dumped cirruscalibrate.txt into there.

Then boot into your USB EFI Shell (might need to turn off secure boot).
Make sure you navigate to the USB drive then go to EFI\Boot

UefiBiosConfig -getconfig=cirruscalibrate.txt

You can also dump your existing config using:

UefiBiosConfig -getconfig=cmosdump.txt

Edit it in notepad or using the edit command, then restore it with:

UefiBiosConfig -setconfig=cmosdump.txt

If the error goes away and the audio fixes itself, then horray!
If you get a red screen of death on reboot about some stupid programming mode, run this:

UefiBiosConfig -setconfig=lockmpm.txt

Good luck


Whoops I meant

UefiBiosConfig -setconfig=cirruscalibrate.txt

like in the screenshot

Couldn't edit the post a 2nd time haha
