Hey everyone,

I'm looking into adjusting the frequency and power limits of my CPU but I will need the advanced menu in my BIOS to do so.

Manufacturer: HP
Model Number: ba109tx
BIOS: Insyde H20 F.55
BIOS Type: UEFI
Download Link: here
(ps. I extracted 2 .bin files, and I am not sure which one my BIOS is)

If there are any files needed, please inform me.
Thanks everyone in advance for your help!

@Lost_N_BIOS could you have a look please?

Do you have flash programmer, such as CH341A? If not, order a set, you need CH341A + SOCI8 / SOP8 test clip with cable.
To know which BIOS you system uses, it may tell you when you run the stock BIOS flash process, sometime during that you should see which one is from your system
Otherwise, we'll have to look at BIOS dump to be able to tell. You may be able to see it in windows system info, or CPU-z motherboard tab. Look for the extracted ID of course, or in system info it may show as Family ID

When you run stock BIOS flash, does it reboot to do the actual flash? If yes, then programmer needed for sure, unless the guys over at BIOS-mods.com forum can help you.
I can unlock this, but in case it's internally signed BIOS, best you have programmer in hand and backup made in advance, ready to recover

Here, do this, tell me what error you get at #2, upload file from #1. Then also do 2nd below spoiler

Please download the following package, and run the command below from each versions folder that directly contains it's exe.
Before doing this, make sure you have secure boot disabled in BIOS, any BIOS password removed, and TPM/Encryption disabled.
Once done, copy the entire folder somewhere, delete everything but any created vars.txt and then repackage this and send to me.
This way all created vars.txt remain in place in the folders of the version that created them.
There may be errors, not all may work, ignore and carry on as outlined

H2OUVE.exe -gv vars.txt

Hey, the BIOS version seems to be the Insyde F.55 from what I can see in the system information.
Here's a screenshot, let me get back to you after doing #1 and #2.

ps. do you have any idea how often hp bioses are internally signed?

Thanks in advance :P

And from the last time I updated the BIOS, I'm fairly certain it rebooted to flash it. I sent you a link in PM to a programmer I found, could you just check to make sure it's the correct one before I purchase it? Thanks!

Hey, here is the result from #1 and #2.


Can I know if I can enable Intel SGX or I must leave it disabled? I had it disabled when I did this.

I will now try the 2nd one and update you.

[[File:biosreg.rar]]

Hey, I managed to do the second thing, I am not sure if I did it correctly though, I did it like the first one, shift right clicked the folders and opened command prompt and inserted that command. Hopefully that's correct :P anyways here is the result. Thanks

Please flash this vars package back by dropping the file linked below into HOUVE 100.00.16.08 folder and running this command >> H2OUVE.exe -sv varsM.txt
http://s000.tinyupload.com/index.php?fil...523345050291647

There will be a list of success/fail, then reboot. Once you've rebooted, delete previously created biosreg.bin and do FPT spoiler step #1-2 again using new file name (such as biosregnew.bin)
Do you still get error at #2 after this? If yes, what error? If yes, also show me image of this output >> FPTw.exe -i

Also, if yes, run these two commands again and tell me if you still get error at #2
1. FPTw.exe -a 0x332078 -l 0x28011F -d vol1new.bin
2. FPTw.exe -a 0x332078 -l 0x28011F -f vol1new.bin << *Edit - Fixed

Sorry, I don't know what Intel SGX is, so I assume you can do whatever you want with that, otherwise I'd be aware of what it is
If you think it's something you should have disabled here, then leave it disabled until we are done

Hey, thanks for the reply.

At the FPT Spoiler second step, I get the error

FPTw.exe -a 0x332078 -l 0x28011F -d vol1new.bin

You're welcome! You didn't happen to take note of the success/fail list did you?
If not, please run that once more, and take an image of the complete output list, or copy/paste like you did for FPT -i above
Then reboot, and run FPT commands again below, w/ corrected #2 command

Sorry, I made a mistake on that second set of FPT commands, please do this for #2 (edited above now)
1. FPTw.exe -a 0x332078 -l 0x28011F -d vol1new2.bin
2. FPTw.exe -a 0x332078 -l 0x28011F -f vol1new2.bin

@9vul14 - We disable BIOS lock and FPRR in 23 + 47, and both flashed in the changes as noted below, so you should now be able to do new #1 dump and pass with that file at #2
Variable Index[023]: Set successfully!
Variable Index[047]: Set successfully!

Ahh, you did, great!!

Ahh! Sorry, I should have had you dump the entire volume for this, not the sub-volume, I forgot it's size may change on edit
Please do this now, and send me the file from #1 (#2 should still pass, please test it to confirm)

1. FPTw.exe -a 0x332000 -l 0x2EC000 -d Mainvol1.bin
1. FPTw.exe -a 0x332000 -l 0x2EC000 -f Mainvol1.bin

Here is the result from the first one.

Second one's result is in spoiler

@9vul14 - Great to see, so yes, no programmer is needed here to flash in mod BIOS!
Now, just to get it unlocked!! I am not 100% sure on this edit, so it may take a few tries, sorry Insyde is not my thing
Flash this back via step #2, and let me know, if you can see this option inside >> Advanced >> OverClocking Performance Menu >> Overclock Feature << If you can't see that let me know and I will make visible, this unlocked several submenus inside the overclock performance menu

Sorry @Lost_N_BIOS, what command do I use? haha I'm quite a noob sorry
