Hello @fairestmeat
I have a F5-573g too, Idk how to flash bios and if it's safe to do this? also I don't understand why you're modifying Bios with Maxwel ,isn't there a advanced menu currently?
here's the exact model I have F5-573G-547K just to make sure

@whatsmyname
Hello! Flashing bios os an easy and safe process If the BIOS you're flashing has nothing wrong with It. And if you have a ch341a programmer is even more safe and easier, cause If something goes wrong you can Just program the working BIOS back.

Post your BIOS at the BIOS modding request subforum and someone will Help you. The process of how to flash is here at this Thread, but i don't know if there is any diferente steps for your model.

And the Maxwell thing is because I can't control dedicated gpu in BIOS, so to change clocks, tdp, etc I need to extract the gpu BIOS wich in this case is inside the main BIOS, mod with Maxwell, insert back on my BIOS and flash it.

*Edit*

Even if your BIOS is the same as mine, still post yours at the subforum and ask for someone to mod it for you. I don't recomend flashing the one thats in this thread cause something might be different.

@fairestmeat what could be different I flashed same bios as yours from official acer support page
Can you give your f5-573g model details

@fairestmeat - Two things I'd suggest you do differently, to rule those out. Use UEFITool 25, and extract Body/replace Body on the vBIOS. And make 100% sure yours is the correct one you are edit if there is multiple vBIOS in there (not looking at BIOS now)
Maxwell may not be able to properly edit that file, does it look as you intended when you reopen with maxell?

@whatsmyname - Please download the following package, and run the command below from each versions folder that directly contains it's exe.
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.

Additionally, please do below, for now skip #2 we know it's locked, send me your BIOSreg.bin file from step #1

@Lost_N_BIOS I ran this command H2OUVE.exe -gv cars.txt and my keyboard got disabled so I have to reboot for every version, is this normal

*edit*
vars : http://s000.tinyupload.com/index.php?fil...664382586033356
bios dump : http://s000.tinyupload.com/index.php?fil...388843101812257
just to make sure I used "Intel CSME System Tools v11 r32" for bios dump because my intel ME version is "11.5 build 1058"

@whatsmyname

Yeah, that happened to me to. apparently that's normal

@whatsmyname - Yes, on some systems this happens, not sure why? Here, copy varsm.txt into the H2OUVE_100.00.16.11 folder which contains it's EXE - http://s000.tinyupload.com/index.php?fil...422054778241965
Then program back via CMD below, there will be a list of success/error, this is expected, then reboot and toss previous BIOS dump out so there is no mix-ups, then dump BIOS region again using new name (like BIOSregnew.bin) and then try to flash it back (ie step #2 in above FPT spoiler)
If success now at step #2, then send me this new BIOS region dump and I will unlock it for you

H2OUVE.exe -sv varsM.txt

@Lost_N_BIOS I got this warning while flashing bios
"GbE Region does not exist." but it flashed Successfully
two thing I wann say to just make sure it won't break my system 1)I have undervoltage'd with throttlestop same in linux 2) safe boot is disabled and I put a master password on my bios
http://s000.tinyupload.com/index.php?fil...969088398437960

@whatsmyname - Yes, that is normal, sorry for not mentioning (PDR error normal too if you see it)
Please remove BIOS password, as well as any Encryption or TPM enabled, then reboot, then flash stock BIOS and start all over. Not sure what you mean about "Safe Boot" but Secure Boot should be disabled for now too, even after stock BIOS flash, disable it before doing rest here.
Also, remove any undervoltage you've done with throttle stop first, reboot and make sure that's removed, then do as mentioned above.

Then start over Dump vars (just using 100.00.16.11) and send to me, I do not need your FPT dump, but toss out all previous ones you've made, so they don't get mixed up with new ones.
I will send you back edited vars again, then you program in, reboot, dump BIOS with FPT using new name again, and confirm you can write it back, then send it to me.

@Lost_N_BIOS Ok I'm doing, do I should keep undervoltage even after flash unlocked bios

Once we are done, you can put all things back to however you want it

@Lost_N_BIOS ok here's http://s000.tinyupload.com/index.php?fil...178322570293837

@whatsmyname - here, program back via >> H2OUVE.exe -sv varsm2.txt
http://s000.tinyupload.com/index.php?fil...228052623190659
Then reboot, make new FPT BIOS region dump with new name, and send to me (no need to confirm you can write it back, we already know you can now)

@Lost_N_BIOS http://s000.tinyupload.com/index.php?fil...991371414959239

@whatsmyname - Here is your unlocked BIOS, flash back via >>> FPTw.exe -bios -f biosregnew2unlock.bin
http://s000.tinyupload.com/index.php?fil...751028476629949

* Edit - Please confirm you can see >> Advanced >> OverClocking Performance Menu >> OverClocking Feature << if not, I will need to do additional edit to reveal "OverClocking Feature"

*** WARNING - To ANYONE with laptop and unlocked BIOS!!!! ***
DO NOT try to enable this graphics card or disable that card, switch cards etc. Otherwise you will end up with no display output (ie black screen) and no way to recover except by blind flash or with flash programmer.
You can change graphics related settings, like changing memory sizes, or core speeds etc, just don't try to disable one card or change which is main etc.
Additionally, be very careful when trying to undervolt CPU, you can leave BIOS unbootable due to CPU voltage too low (Sometimes even 0.05 is too much)

*** WARNING *** - This BIOS is user specific! If you are not user whatsmyname at Win-RAID.com forum, DO NOT USE THIS BIOS!!
If you do, and you are not whatsmyname, then you will loose your serial, UUID, OG NVRAM, and possibly LAN MAC ID as well.
You have been warned!!!
