Re: Help unlock HP 830 g9

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)...
