    You mean patched rompaq.exe flasher which is a part of the toolkit? As far as I remember it gives an error.

    Yes, I meant that. I hope there's a way to downgrade the BIOS.

    Would anyone by any chance still have "HP_nx9020_sp31140_3084F16_no_whitelist.zip". It's ancient, I know, but it would help a lot.

    Thank you. I didn't noticed remake.
    Gonna test it asap.

    It does work. Wifi card is detected by lspci, system does boot without any whitelist warnings/errors.
    But it seems like wifi switch is permanently turned off in bios, because rfkill shows wifi is HARD blocked.
    Means hardware disabled, not by software(os).

    i thought about masking enable/disable pin on wifi card. but cant find which pin is it on minipci. Its hard to find as im flooded with minipcie pinouts when searching for this.

    No problem. The knowledge I was using to remake the mods for Rompaq systems is legacy of TTAV134 and other contributors. I've just copied their work.

    I'm not very familiar with acpi tables, which is what dsdt is.

    But can tell you that each computer device is specified in these tables for the correct operation. Devices are described by various expressions according to acpi specs, including Methods.

    IMO, since the buttons work in windows, the method from dsdt must be alright. And it's rather a linux issue. I'm not a coder, so can't do anything about this.

    However, if no driver is required for media buttons to work in windows, there is a chance that they work not as a separate device. I.e. produce basic scan codes instead of actions that are handled further.
    Then you could maybe re-assign the buttons somehow.

    The requirements for i915 mobile are the same. C2D init code is the main issue. If original bios apic table has at least 2 cores specified, there is a chance the code is present as well.
