Oct 16, 2016 GUIDE – HOW TO EDIT THE DVMT SETTINGS FOR INSYDEH20 BIOS This is a somewhat generic guide on how to change Bios settings for locked Bios used by Acer, HP and a few others who use InsydeH20 bios. This guide has been used on an Acer V3-371. HP Insyde BIOS recovery steps. I bought my daughter an Acer Aspire 7720 (with InsydeH2O bios) that she used without problems for almost two years. The last thing I did on the notebook was reformatting the HDD through HP Support Assisstant when all of a sudden the screen went black and next thing you know I have a laptop with a corrupted.
First why did I am asking this here:I called HP support and they said if I want to reset my BIOS password then I want to go a service center and they need to replace bios chip and motherboard ( i have no idea why ). This is why I am asking here for any insights.My laptop is HP ENVY - 17-ae108ca and I did set a BIOS admin password ( i regret now ) and unfortunately I forgot that. This laptop is just two weeks old and I did install centos in that now everything works fine but the problem is every time I need to boot priority menu and change to centos to boot to centos otherwise it will boot direct to windows.So is there anyway I can reset the bios password? I tried multiple times with wrong password and I got this messageSystem Disabled i 49915935 Any help will be much appreciatedIs system restore will reset BIOS password?

Bad part: they hid the forms differently and I don't know YET how they done it.There are three ways to hide the forms: by code within the SetupBrowser (my bios), by VSS-Data (inside bios data) or by Form OP-codes.The VSS-data is formatted in the downloaded bios. If you flash it, it takes the VSS-data, which is already installed on your computer (which I don't have:-))So maybe you see any way to dump YOUR current bios? With linux it actually is no prob; I don't know if HPs windows tools offer a way to backup your current bios. They actually should. Could you please check and if possible upload a backup of your current bios?That might be a great help to have your current bios WITH VSS-data:-).

Hi akbar,ok, found the spot.Bad: Insyde doing their work better. They always implemented the code which was showing 'advanced' stuff.
Not in your bios. Actually its just a small part of code missing, but I am not able to insert new code.Good: I will find a way to patch the underlying functions. May take some time.Until then: What I can to is REPLACE an existing Form (like the diagnostic one) with the 'power' or 'advanced' one. So you could flash 'advanced' bios, change settings, flash 'power' bios, change settings, and then flash back orig bios.Maybe I find a better way. I come back on you when I got it.

I come back on you when I got it.thanks i am not using this form (Main, security, Diagnostic,Exit)if you replace two of this form whit advanced and power.you do a great work.thanks for your time that spend on this.

I do not want to brick your computer:-) So you really should only do it if that method works (read on my page or search internet. On some machines the keys you need to hold down are different)Actually I cannot test the bios here. The patch is very safe, so I do not see problems. But actually we only know after flashing:- Thanks.i flash my bios several time and i have recovery usb for it. Hi akbar,bios has been patched.

You probably have much more luck than akbar; code for all forms is included and just hidden by a little switch, what I can see so far. So should be possible to patch.Will get back to you when I got it. Tomorrow Final Fantasy XIII-2 comes out back here in Germany.

Probably will have to play some before patching:-)What you can try: the first bios you posted is somehow corrupted. Should also be 2MB or some HP package.
Try to get a 'real' one from HP or give me some link; since when I patch your dump only you can use it, but others would get YOUR settings. I would like to put all patched bioses on my side, but I dont want to do it with a dumped one:-).
