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)

Method 2

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

Use a script to do those Find/Replace for you.

Create a file PSPad editor\Script\VBScript\ModnVidiaInf.vbs in the PSPad application directory.

Add the following code.

const module_name  = "Mod nVidia nvcvi.inf for gtx670mx with p150hm"
const module_ver   = "1"

Sub Init
  addMenuItem "Modify inf file", module_name, "ReplaceText"
End Sub


Sub ReplaceText
  Set editor = newEditor()
  editor.assignActiveEditor
  s = editor.Text
  s = Replace(s,"DEV_11A1&SUBSYS_51051558","DEV_11A1&SUBSYS_00001558")
  s = Replace(s,"%NVIDIA_DEV.11A1.5105.1558%","%NVIDIA_DEV.11A1.0000.1558%")
  s = Replace(s,"NVIDIA_DEV.11A1.5105.1558","NVIDIA_DEV.11A1.0000.1558")
  editor.Text(s)
End Sub

Save it. Close it. Restart PSPad.

Now you will have a new entry in the Sctipts menu named "Mod nVidia nvcvi.inf for gtx670mx with p150hm" with a Sub menu named "Modify inf file".

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.

Use the new Script menu item to edit the file.

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.

I upgraded the mxm graphics card in my clevo p150hm from gtx 460m to a clevo gtx 670mx

1. After the upgrade the booting behavior of the notebook was strange..
   
   1. 
      
   2. The bios screen does not complete when detecting hardware
      
   3. It shows the AMI logo and one line of text "AMIBIOS © 2010 American Megatrends, Inc."
      
   4. It does nothing for 30 seconds, then beeps once.
      
   5. Again it does nothing for 30 seconds then beeps once.
      
   6. And again it does nothing for 30 seconds then beeps once.
      
   7. Then it shows a flashing white cursor at top left of black screen for about 3 seconds.
      
   8. The cursor then drops down a few lines then Windows begins to boot.
      
      
   9. Other changes in behavior at boot time are...
      
      1. It wont enter the bios setup by pressing the F2 key
         
      2. It wont enter boot select by pressing the F7 key
         
      3. It will enter the Windows Start up mode selection by pressing the F8 key, but only if pressed in the 3 seconds while the cursor is flashing.
         
      4. Attempting to boot to DOS or Windows PE from usb results in the same sequence of events (1 to 6) ending with a flashing cursor on a black screen.
         

[*]On the first boot after the upgrade Windows loaded the Video Reference driver (screen looked like it does in safe mode)

1. After some research I installed the most recent nVidia Video Drivers with modded *.inf as per instructions from LaptopVideo2Go
   
2. This restored normal video function in Windows.
   
3. The boot issues remained unchanged.
   

[*]Thinking that the vBios version may be the problem I downloaded Clevo 670mx - 3GB - 80.04.58.00.03 - 'OC edition'_rev02.zip from here.

1. From within Windows opened a command promt window as administrator
   
2. Changed directory to the one with nvflash and the OC vBios in it
   
3. Ran nvflash --help (to make sure the output made sense)
   
4. Ran nvflash --list (to see if the card was recognised)
   
5. Ran nvflash -6 670mxOC.rom (-6 = ignore PCI subsystem ID mismatch) (670mxOC.rom = name of the file I was flashing to)
   
6. The flash completed successfully.
   
7. After PC restart the only difference I noticed at boot was a listing of the vBios version just as the cursor started flashing.
   

[*]I've NOT upgraded BIOS from P150HM to P170HM. but I was considering it so as to be able to OC Graphics and Processor.

1. Bios Version: 1.01.14
   
2. KBC/EC Ver. 1.00.13
   

Has anyone got any good suggestions about how to get a normal boot functionality back?
