Use the information you just gathered: Google the model number, SKU, look for its official GPU and memory clocks. Navigate to the TPU VGA Database and begin looking for your card in both official and unverified uploads. In the same opportunity, remove dust from the fans with a toothbrush, clean the card with alcohol & cotton swabs and then reapply thermal paste.

Inspect the card from both sides, look for model number (on the stickers and card itself), serial numbers, board revision, clock frequency (e.g. In case you don't have a backup, remove the graphics card, take off the cooler, check which memory chip is used (Samsung/Hynix/Micron/Elpida) including exact model (e.g.

If anyone can look into it and advise, point me in the right direction, I'd be really grateful.Almost every day there are new threads regarding bricked graphics cards due to wrong BIOS flashing, and since eidairaman1 is no longer around to help, here is a guide how to deal with a bad VGA BIOS flash.įirst off, you'll have to find a copy of the original BIOS. It is possible that it's not even the BIOS responsible for this, but the Intel Management Engine firmware, but I'd like to make sure. I'm not sure what other ways could be used to set the bits. My knowledge of Assembly is limited, I looked for any mov/bts/btr/or operations involving 0圆10 - there are a few of them, but I don't see a clear mov then bts anywhere. What I'm looking for is a module where bit 63 (3f?) of register 0圆10 is set - it's responsible for locking the Turbo Power Limit settings, which is the most important part of overclocking an extreme Sandy Bridge. The ROM itself doesn't seem to be encrypted from what I can tell.
The installer package does have RSAcrypt files in a separate folder, it may be that HP checks it when flashing. So, I read that these BIOSes are RSA encrypted, however I was able to unpack the ROM file with PhoenixTool and disassemble it with ndisasm. It's a HP Elitebook 8760w, and since I dropped in an extreme processor, I feel I should be able to overclock it (it also has the usual whitelist issues and a dreaded 1333MHz limit on RAM speed, but one problem at a time). I've recently decided to try and mess with my laptop's BIOS. Here are some more info I managed to get from UEFITool I have tried using efi shell to setup_var 0x39 0x01 (that's for ahci boot) and it failsĪlso tried to disable BIOS Lock 0x4bb fails as well with unable to set efi, but I know why cause its locked by HP could some one explain?īoth of these are extracted from "setuputility" branch with GUID of FE3542FE-C1D3-4EF8-657C-8048606FF670 rom file and Setup.ffs in case anyone needs it to help me.īIOS FILES.zip (Size: 5.11 MB / Downloads: 0)ĠxAC1BC System Configuration (0圆3 from string package 0x0)ĠxADD9C Power (0x41B from string package 0x0)ĠxAFE6C Security (0x133 from string package 0x0)ĠxB13AC Advanced (0x1C9 from string package 0x0)ĠxBFDAC Main (0x103 from string package 0x0)ĠxC006C Exit (0x187 from string package 0x0)ĠxC013C Diagnostics (0x49 from string package 0x0)ĠxC025C Security (0x3D from string package 0x0)ĠxC031C Main (0x4 from string package 0x0)ĭon't know why the offsets are different.

Opened the Setup.ffs in HexWorkshop, but I can't find anything corresponding to the magical:Ġ1 01 00 01 01 01 numbers, or anything near it (neither zeroes, or I think any combination)Īnd so, here I am, stuck trying to mod my bios.īIOS Date: 00:00:00 Ver: 1APTJ (although the BIOS Information, and the info in bios itself says its P09ABE) Found the GUID in file and extracted it as-is to Setup.ffs Found the C7 Index with filename "Setup" and copied its GUID:
The menu is not just hidden, its in fact some other Samsung-like menu, located near the original one) rom file with AMIBCP 4.53 and set the stuff I want to be visible to "USER" Read BIOS with AFUWINGUI 3.07 -> backup.rom I tried to unlock the BIOS in my notebook, but I'm stuck on "change the bits in hexeditor" part of the fun.
