Example - Fixing a BIOS flashrom

 

Step.1
 Find a flashrom(IC-CHIP) on Mainboard.
 Most of case, a BIOS flashrom is near South Bridge and it is pluged on removeable socket or soldered on M/B.
 And check the flashrom is removeable from M/B.
 If flashrom is pluged on socket,  it is removeable.
 or If the flashrom is SMD(soldered) type, you have to use other method* to handle it.
 * SMD reworks Tool, Reverse socket, Online adpater or ETC...  
   
 

                                            Figure.1 . Flashrom on Mainboard


Step.2
 Then, check your flashrom is compatible with compatible list and it is supported packakge*.
 If not, programmer can not work with the flashrom.
 You can confirm flashrom's name on top surface of flashrom.
 If there is a sticker on it, remove it first.
 * Programmer default socket supports only DIP8 and PLCC32 package flashrom.
   If other package, please use external adapter.  
   

                                                                    Figure.2 Confirm Device name.

 

Step.3
 Carefully, unplug the flashrom from it's socket.
 ** Socket and flashrom leg is not HARD.
 ** Remove All power(AC and battery) before do it.
 ** If you don't have PLCC ejector, follow next method to unplud the PLCC32 type flashrom.


 
                                                                  Figure.3 - Pull up little just one corner.
 

 

                                                   Figure.4 - Pull up other corner. and again...
 

 

    CAUTION : If flashrom is soldered directly on M/B surface(it is called SMD type),
                     You have to de-solder it from M/B with SMD reworks tools.
                    After desolder, you can use SMD adapter.
                     or Some M/B supports on-line adpater.

   * PLCC32 flashrom can be used with reverse socket.
   * TSOP32/40 FWH/LPC flashrom can be used with 9~10 soldering points.
   * SPI flashrom can be used with some soldering points or reverse socket.
   * All these work are dependent on M/B design. Contact me.


Step.4
 Plug the flashrom to PROGRAMMER's socket.

* All flashrom has direction and pin-order. 
The PLCC32 flashrom has corner notch and DIP-8pin flashrom has half-moon notch at upside edge.
SOP-8 flashrom has dot-mark or taped edge at Pin.1 side


                                                                                      Figure.5 Pin-order

 


Step.5
 Plug NANO USB PROGRAMMER to USB port of PC.
 * Install USB driver and S/W before this.


Step.6
 Run NANO BIOS programmer software.
 If there is no probelm, S/W will shows Pluged Status.

 

Step.7
 * Important : To work NANO USB Programmer, S/W must recognize what flashrom is pluged on programmer.
 To confirm this, press [ Get ID ] button first.
 If there is no problem, you can see the recognized device in [ Device information ] box. 
* If Programmer is pluged, and S/W + driver is installed correctly, LED will blink one time at this moment.
* If you can not see the correct device information, programmer will not work with the flashrom.
  Please check the forward steps.
  Even if you do that, device information was fail, try with other flashrom or contact me.

 

* Tip
  Some times, some Pins in PLCC32 socket is bended to inside.
  This can make disconnection problems.
  You can fix it like next photo.


 

                                                           Figure.6 - Pull out bent pin to out-side.

Step.8
 Press any function button you want. (Write, Read, Verify or Erase)
 Then, software will ask you a necessary filename or agreement of progress.
 You can see the [Green progress bar] when reading/verifying the flashrom, and [Red progress bar] when programming/erasing.

 And the LED is turned on while PROGRAMMER is running.
 When operation is complete without error, you can see the Success message on status bar.
* When writing, download BIOS file first from Homepage of the M/B manufacturer. 

 

Step.9
 Unplug flashrom from NANO USB PROGRAMMER.
 Then turn it back to the socket on first mainboard.

 

* If the PC doesn't work after updating, re-try from first step.
however, if the "Verifying" was succeed, it would not be programmer's problem.
Please check the BIOS file and M/B version and file size.
Most of case, file size must be same with flashrom size.
And check PC state and there is not bended pins in the flashrom legs or socket.
