[REQUEST] Compaq Presario CQ62-225NR

[korpse413]

Request for a fully unlocked Insyde BIOS (or at least access to Advanced / Power tabs) for my laptop:

- Model# CQ62-225NR
- Screenshot of BIOS below
- Link to BIOS here (sp52598.exe)

Would love any help from anyone.  I have learned a substantial amount searching for a solution to my problem, but still have no solution.  What I could gather is I might have multiple tabs 'hidden' but can only have access to two more unless I replace existing?  I just want tabs that affect any type of performance so I can have total control of my machine (like it should have been out of box in my opinion...)

I have followed a few tutorials and would like to thank people such as SnakeyJake, Crahzee and Donovan6000 for the information I happened to stumble upon, although all posts seem to be dating quite a few years back (the laptop I am asking assistance with is over 5 years old so I guess it makes sense..).   

So far I have successfully making a bootable usb for UEFI Shell access (I am clueless in this realm), and even attempted to follow Donovan6000s guide here.  I got as far as locating the conditional jumps, call functions and cross referencing portion until I simply drowned from not knowing the material.  I was following the guide to a T, but wasn't sure what the cross referencing portion was really accomplishing,  I also noticed if I messed up on a portion because on his end in IDA Pro he shows (in his case) 'text:000000018000105A' but in my IDA Pro is read 'source:000...etc...'.  I figured I messed up somewhere before this because I failed to locate any conditional jumps (in the guide we are looking for jz and jmp, all I could locate was js...

Novice question here, the fact that my BIOS version from the HP support site is sp52598.exe, are all BIOS with this filename one in the same?  Or are they uniquely made for each board?  Wasn't sure if they are interchangable since parts might overlap across different models.

I am just explaining my knowledge so far, which is very little in the matter.  I am eager to learn as my trade is in I.T. just more on the hardware side, so it is a refreshing hobby.  Cheers, happy 2016.

It works!  See attached.  Cheers man.  Must have overlooked this version in my searches?  I suppose I should've looked up all models of laptop mobo with a part# of 1444?

Now to learn how to even use these settings correctly...

Here is Advanced tab only unlocked. As you see Diagnostics tab replaced to Advanced (It's specific HP bios, bios of another vendor let unlock other tabs without hide current tab).Power tab, AMD_CBS, Debug are still locked.This bios is RSA signed and produced before 2012 so it can be modded.

So the original Compaq BIOS I linked is not RSA signed and cannot be modded?  What exactly is an RSA signature, just for learning purposes.


Also, It appears I have already bricked the BIOS *facepalm* just by simply upgrading to Windows 10...  Is it because the BIOS sees a foreign Operating System in the 'Main' tab and freaks out and hides?  I suppose I can live with it...  or just revert back to Windows 7.

The whole point of me venturing down this road was to allocate more system RAM to the GPU (installed 8gb RAM over its stock 2gb).  The laptop would be for my gf..  she wants to play a game (Game of Thrones Telltale via Steam) that recommends minimum 1gb Video RAM.  And to maybe tinker with fan speeds just because it runs super hot.  I guess I can stop being cheap and buy a better cooling pad for the thing, or even a new device entirely.

I looked at laptop specifications and found that laptop have untegrated graphics (ATI Radeon 4250).This video is not good solution for games.You may get some freezes during playing or game cannot launched maybe.You should find laptop with discrete graphics with dedicated 1gb VRAM (for example ATI radeon 4650, 5650 series or Nvidia 230 GT or above). I think your not good compatible with this game.
I dislike AMD chipsets and CPUs because it are very hot, quickly degradading and not so perfomance as Intel.
But last word for you and you can try to use this laptop.
Good Like!

Hello,
I want to unlock the BIOS for this device. It is an InsydeH2O rev. 3.5, and looks like it has a legacy BIOS only. I heard from someone it includes an EFI-like implementation, but do not know how to use it. If possible, maybe someone can also provide me instructions on how to unlock that?
