I am not sure about what you have to do now, have you read thoroughly this thread? There is everything you need to know about flashing cards but if you haven't got the proper vbios..

Hallo I ve installed a GTX670mx in a Clevo. Everything works just fine but if I connect a DVI-VGA adaptor, although Windows sees the vga connected display, the display itself does not recognise anything on its input. Here a thread with some info about what I ve done to get it working. 

Hallo everybody.. so nice to see that this worked out for others too, the card is running just fine and I d say a bit too cool, so how to squeeze out some extra clocks here? With Invidia Inspector I can just get  a 315MHz increase maxing out at 750MHz. Is there a mod to unlock the card?

Hey, it is pins 1 and 4, chip select and GND. Just shortcut them before turning on.

This is my howto as is.. work in progress 

blind flash.zip

tch150 can you PM me an high res picture of the chip? that would be a nice add on for the howto. (mine is SMD package)

Hi, sorry but I haven't seen your post before. I can't get a big enough picture of the K5000m to try to find out the eeprom chip so please if you are still trying to get it working try to snatch an high res picture of both sides.
I was also meant to write an howto which I have not completed, coming soon.

Simone

Card is working ok now, at full GPU load temp. is just 60 degrees, so I think there is room for a bit of overclocking, since EVGA Precision ican't be used, what do you advice ?

S.

Fixed, the problem was not related to the VBIOS or anything on this thread but to the EVGA Precision / Windows 10 combination ..

Hi where can I find the EDID bin file for glossy display of P150HM AUO B156HW1 v0 ?

Thanks

Simone

EDIT: I think I can get it from here

​B156HW01 V.0.pdf

it can be retrieved from the table at the bottom of the document.. but how to make into a .bin file?

S.

EDIT 2: I managed to get a proper EDID and reflash the display.. what a nightmare ..

So a few considerations for those who are facing a similar situation:

• the shortcut to overcome the VBIOS safety block has to be between Chip Select or Chip Enable and VSS/GND
  

• use a USB stick with freeDOS and a LED, this is importat as it is the only active feedback you ll have in the broken machine
  

• create the shortcut, hit the power button and wait for the usb stick led to show activity, that means freeDOS is loaded in RAM, after that you can remove whatever you were using as shortcut
  

• you can pipe info from DOS to a text file with the ">" symbol so to test that everything is ok do something like "DIR > dir_info.txt" then pop out the usb stick and plug it into another computer and see if in dir_info.txt you have the listing of files and dirs of the usb stick
  
• you can plug it back again (awesome), no need to restart the computer, it will recognize the usb stick and you ll be back at work on your faulty machine
  
• nvflash has got a -L option that stands for logging data, it s very useful to see what s going on ex: "nvflash -L mylog.txt -6 myrom.rom" then pop out and in the usb stick and check the mylog.txt file it will tell you how things went
  
• a friend ponited me to this great manual for nvflash it is attached here [ATTACH]16453[/ATTACH]
  
• if you don t say otherwise nvflash has a sound feedback, COMMAND - Enter - press Y - Enter - 3 beeps - press Y - Enter - wait wait wait - one beep - READY (the second Y I am not sure about it), it took me many tries to get to the second and final beep, I am not sure why it didn t work the first times, typos, not waiting enough, dunno..
  

@Prema, thank you now the driver installed correctly but I am not sure I am seeing the card running correctly, the main problem s that the laptop screen is not coming up, the HDMI connected is ok but the laptop display is not being recognized.

Much thanks and kudos to Prema who made a new vBios for my graphics card.

All the issues reported in the first post are resolved by the new vBios.

The motherboard's bios reports the Graphics Adapter Name as empty <empty> but uses the Graphics card without problem.

The nVidia Drivers will need to have the nvcvi.inf file edited before driver instalation.

The method is as follows;

Method 1

------------

Download the new driver.

Double click on it to extract it. (it usually extracts to C:\NVIDIA\DisplayDriver\)

Find the nvcvi.inf file (in my case it was at C:\NVIDIA\DisplayDriver\350.12\Win8_WinVista_Win7_64\International\Display.Driver\nvcvi.inf)

Open it in PSPad.

Using the Replace function,

Replace all occurences of DEV_11A1&SUBSYS_51051558 with DEV_11A1&SUBSYS_00001558 (You can replace any GTX 670M Dev ID code you wish)

Replace all occurences of %NVIDIA_DEV.11A1.5105.1558% with %NVIDIA_DEV.11A1.0000.1558% <------ my Hardware ID, your one may differ.

Replace all occurences of NVIDIA_DEV.11A1.5105.1558 with NVIDIA_DEV.11A1.0000.1558

Save the file. Close it.

Run the Driver installer. (It should now install)

Hope this helps someone as I have been helped on this forum.

Before delving into the VBIOS flashing afterthoughts, it seems like I can't install the driver, I followed what Romulan wrote but I get an error

Ok it wen through, I ll post later about the steps.

arr no dice yet!

I do hit Y and Enter and I can see the usb stick blinking, furthermore I piped some nvflash commands to text files so I am sure that both DOS and nvflash are working correctly but when I restart I am back to the same point. How long should it take to flash the eeprom? Should it shutdown/reboot by itself?

I ve also removed the power supply and the cmos battery.

nvflash --check

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.

Still not working, maybe I am missing some steps.

- I got the .rom file and I ve added it to the root of the USB stick

- I turn on the laptop with the aforementioned technique

- type "nvflash.exe -i 0 -6 GTX670MX.rom"

- hit enter

- usb stick flashes

- wait some minutes

- unplug the supply for 30 secs (no battery on this unit)

- turn on again and I am back where I was before

I wonder if after the nvflash command there is something else i have to select.

Hi, I think i have some important news here.

-- first of all, this is a rather dangerous thing to do so beware --

I asked around and they told me that you can override the vbios safety check by shortcutting CS or CE (depending on the chip) with VSS/GND. That should let you pass POST. This doesn t mean that you ll get anything in your display, blind typing is needed anyway.

So I got a shot at the GTX670m

[ATTACH=CONFIG]16433[/ATTACH]

the chip in question is http://www.zlgmcu.com/mxic/pdf/NOR_Flash_c/MX25L2006E_DS_EN.pdf , the needed pins are easily exposed on the outer side, I could have done with a pair of nail scissor i had at hand but I waited to go to our hackerspace to use proper clips and anti-static wrist band (just joking, I did it with the scissors and the laptop standing on its side...), so, just short-cut those 2 pins and turn on the laptop with your free hand..

The USB stick started to blink (goood) and there was nothing on the screen, I blind typed nvflash.exe -b backup.rom, (USB blinks again...), waited a while and plugged the USB stick on another laptop. backup.rom is there, so it looks very promising.

Looking forward to flash the proper VBIOS now.

Simone

ok, as far as I understand, that must be somebody with an Optimus enabled motherboard right? So at least it can fallback to the integrated GPU?

Where can I find the proper file for flashing ? Is it Clevo 670mx - 3GB - 80.04.58.00.03 - 'OC edition'_rev02.zip ?

Thanks for the support.

Simone

I did a little resume of what's going on right now:

P150HMx

BIOS: 1.01.14

KBC/EC: 1.00.13

GTX560m

VBIOS: 70.26.29.00.06

GTX670mx

VBIOS: 80.04.67.00.06

(with 560m installed)

1- no ssd, no DVD

2- usb stick with DOS boots properly

(with 670mx installed)

1- no ssd, no DVD

2- usb stick with DOS (working confirmed)

3- appears "note style" splash

4- F2 and F7 do not work, nothing happens

5- fn-1 does work (max fan speed)

6- system beeps 3 times every approx 30 seconds

7- white blinking cursor appears top left

Nope, with the GTX670mx I am not able to get to DOS. I am using a properly formatted USB stick with which I ve used to flash the latest BIOS/EC (removed the SSD and the CD/DVD). But I have at hand the 560m and I can try a dry run and then a blind flash.

Hi, so today I tried to install the new card (GTX670mx), when I star tthe system, I cannot enter bios hitting F2, the laptop beeps twice anery 30 seconds or so then the screen goes blank, nothing else happens.

I reinstalled the old GTX560m so I can access the OS (Windows 10) and install whatever is needed but I am lost here as I am not sure about the proper steps to take.

Any hint?

Simone

Hallo, I am almost in the same situation, upgrading soon from GTX560m to GTX670mx, where can I find the vBios file? I entered Prema's site but i cannot see files for P150HM, can I just use the files for P150EM ?

Thanks

Simone
