Hi svl7,

The size of the ROM image is perfectly fine (95744 bytes), see the output of the command below:

>nvflash -i1 --pciblocks

NVIDIA Firmware Update Utility (Version 5.142)

Adapter: GeForce GT 750M (10DE,0FE4,17AA,3802) H:--:NRM B:02,PCI,D:00,F:00

The display may go *BLANK* on and off for up to 10 seconds during access to the EEPROM depending on your display adapter and output device.

Reading adapter firmware image...

Location Size Type

000000:0175FF 95744 x86

Still, nvflash won't flash it...

The previous ROM is of the exact same size, yet it flashes fine. Strange!

Greetings,

Auke

Not sure what's going on, because what nvflash tells is not true. I'll check again to make double sure.

BTW, is it possible to hide not working options in the modded bios, to make usage of it completely safe?

If I update to the unlocked bios (just got my y500 with 2.02 on it stock) do I have to also push that update to the 2 750M cards or are they ok alone? For now my reason would be to update the NIC card only.

thanks for this!

@the 750m SLI flashers who get errors... try flashing with the Windows version of nvflash.

Use the latest version that I posted in the desktop section of the forums, and if it doesn't work try forcing it with -4 -6

Alright so I am new to overclocking and thought I would try it on my y500 sli on bios v.2.02. But I ran into some problems that I was hoping someone would be able to help me with. I was able to put dos on my flashdrive, but when i try to create a backup of my bios I keep running into problems. I tried using the ftpbios program and got this error message...post-14852-1449499568101_thumb.png

I got that message after I ran the .bat file, and i tried running it as an administrator, but that didnt do anything.

So after that I used the win64 version and tried doing the same thing and got a "fptw64.exe is not recognized as an internal or external command. operable program or batch.

Ive done hours of reading through forums (mostly this one) and cant find anything.

Also Ive tried replacing the fparts doc and it didnt help.

Any help what so ever will be greatly appreciated.

Right click the fptw64.exe, properties, compatibility tab, check mark 'Run as administrator. Then try double-clicking the backup.bat that is within the fptw64.exe folder. Report back.

You need to be in the same folder as the fptw tool, shift-right click in the folder where you saved it and then click on "open cmd here". Then try again.

I think I really need to write a guide about basic command line usage...

Edit: Lol, I'm too slow.

I thought i was following the directions in order... To create the modified bios I need to use the fpt flash tool, correct? After i make the modded bios then I move everything onto the flash drive.

Yeah, and then you shutdown your system and boot from the flash drive. You need to run DOS for that tool.

Huehue I just placed the order for the Alienware 18 with SLI GTX780M so I will be able to reach even higher 3DMark scores.

And one wonders why you even bothered with the Y500 in the first place when you had that kind of dough to spend. :rolleyes:

Well...I wasn't a fan of the previous design on Alienware, it was too vulgar and flashy for me personally, but somehow I like the new design a lot, very clean and streamlined. On top of that, the name GT750M on the Y500 made me think that it'll be some newer generation GPU, which tricked me into getting it in the first place, and apparently it's just the same as GT650M. Although the same could be said with the AW, GTX780M has 1536 CUDA cores, so with some tweak and svl7 vBIOS mod, I could prob make it run at speed close to a desktop GTX 680. And with two of them, if the game scales well with dual GPU, dual GTX 780M should come close or even matching the performance of a desktop GTX Titan.

Also, I made a lil bit of money from selling tons of old stuff recently. And I will be selling this Lenovo too, and that'll offset the cost.

The biggest flaw of the Y500 had been the left side of the keyboard, near where the main vent is. Running the CPU unthrottled with max overclocked GPU when playing Dota 2 just makes it too hot for my pinky finger. Compared to usual AWSD/MMO/FPS gamers, in Dota 2 I have to press F1 a lot, and that means extending my left palm much further to the left than a normal user would do, which means my left pinky finger and ring finger are often over the vent. It's not terribly uncomfortable but it's distracting and could cause death in the game and I don't like dying. :sweat:

I also don't like the fact that I can't put another disk drive in the Y500. Msata cost more than SSD, I'd prefer a laptop with dual disk bay.

Some say one could easily build a desktop beating the performance of the AW, and I agree with that, but I just can't have a desktop as of now. Desktop uses way more power and I can't carry the monitor around.

As a sidenote, it seems that Nvidia has improved their drivers somewhat, and I could get better FPS even if I run the GPU and CPU at lower speed in Dota 2. It's a noticeable improvement, maybe around 15-20%.

      Hello there!
      I am new on the forum. I'd need some help. I own a lenovo ideacentre t540-icb g, and i would need to unlock all the options in my bios, especially overclocking and thermal configuration. I tried with both amibcp and mmtool, but i didn't succeed (Error 18).
      I wonder if you could help me or give me some advice.
      Thanks in advance.

      Hi,
       
      I need help in fixing my Thinkpad.

      I just got a T440p yesterday. It was working perfectly until the following:

      I reinstalled Windows and then I installed Vantage.

      I installed all the latest drivers.
      I also choose to install the bios update. The bios update ran in Windows and it asked me to restart. After restarting, the screen was blank. I tried powering it off and on and I saw the Thinkpad logo but after that the screen was blank.

      I tried powering on and off again and there's no Thinkpad logo now and the screen is just blank with the green power on. No sound, no nothing.


      Here's what I tried:
      Pressing the power button 10 times and then holding it for 30 seconds. Unplugged and battery is detachted Detached the CMOS battery and the reattached it Removed the ram, harddisk and optical disk drive. Attached the battery and inserted the charger. I turned it on and there was a couple of beeps Tried pressing FN+R and created a bootable USB I'd like to ask: How do I fix this? What do I need to do?
      Can I reflash the bios in some other way? Do I need to buy a new motherboard? Will this solve the issue? It's my first thinkpad and I'm really excited but I was bummed out that this happened. Can you please help me?

      Thanks in advance!

      Hello everyone! I am looking for an answer to a problem I cannot find a solution to ... I purchased an Amd wx 4150 MXM GPU module su e bay to upgrade my HP 8570W Mobile Workstation which is currently equipped with a Fire Pro M4000. Once the new GPU has been installed, the PC screen no longer turns on but works only with external monitors connected via the docking station. The same happens once the drivers are updated! If I put the old card back on, the integrated monitor starts working again ... How can I fix it?

      Bios Release Version – v2.0.0
       

       
      Updated or Modded Items:
      A11 UNLOCKED BIOS FOR m18Xr2 (UNLOCKED BY SVL7 AND FULL CREDIT GOES TO HIM FOR UNLOCKING!)
      SVL7 Also created the PRR2.EXE tool that allows you to flash the new bios by unlocking it.  (FULL CREDIT GOES TO HIM FOR THAT FILE PRR2.EXE)
       
      Here are ALL the things I've added, modded, and enhanced on this bios -
      I've added FULL LEGACY SUPPORT ON THIS BIOS with ONE or TWO CARDS (SLI).  You can FINALLY use Win 7 OS on your machine and run the 900 series GPU's! 
      This is a MAJOR breakthrough!
       
      LEGACY SUPPORT Confirmed.  Works with 900 series GPu's in single OR SLI formation Updated the Intel RST Legacy to v12.9.0.2006 (Supports TRIM in RAID0 - CONFIRMED) Updated Intel RST UEFI to v12.9.0.2006 (Supports TRIM in RAID0 - CONFIRMED) Updated the ONBOARD Video Card for the HD3xxx to v2171 - FROM v2132 Updated ONBOARD Video Card for the HD4xxx to v2171 - FROM v2132 Updated the LAN Firmware & PXE Boot from 2.0.5.9 to v2.0.6.6 ADDED NvMe Support for m18xr2 ADDED M.2 support for m18xr2 Updated CPU Microcode to v29 for the 2900 CPU's Updated CPU Microcode to v1c for the 3900 CPU's Updated GOP Driver for Intel Sandy Bridge CPU Updated GOP Driver for Intel Ivy Bridge CPU Updated MAIN GOP Policy module for the m18xR2 Eliminated some code that wasn't used in the m18xR2 Updated CSM Module (v2) Streamline some coding to make mod(s) run a little more efficiently (v2) Added FPARTS.TXT to rar file in v2. (I had forgot to add it in v1) v2.5 to be released shortly.  I've updated a few more modules that I didn't realize could be updated.  (It's only 3 modules, but it's still an update!)   It should be released in about a week.  Hope this helps ya'll!  
      Instructions to flash:
      Use a flash drive to create a boot disk into dos Unzip ALL files into the root of the flash drive (flash.bat, r2final.bin, fpt.exe, flash.bat, prr2.exe, fparts.txt,m18r2.hdr, m18r2.hdr.bin, readmefirst.txt) BOOT INTO DOS – Note, that when you set the bios to legacy in order to boot into dos, you MAY have to reinstall OS!  (Just be prepared to reinstall no matter what) Once you boot into dos, run the file flash.bat It will unlock your bios (THANKS TO SVL7’s BIOS UNLOCKING TOOL – ALL CREDIT TO HIM FOR THIS TOOL!) Let it flash… Reboot your pc, and enjoy the MASSIVE updates!  
      Be on the lookout as I do plan to release newer version with more updates in the future.  However, it wont be for at least a few weeks as I'm now working on legacy support for the m17xR4 and several other systems.  So please be patient!
       
      ENJOY!
