Flashed the BIOs to Version 2.02 now it only powers on

I flashed the BIOS from 1.01 to 2.02 on my n6650w. I received video after rebooting and I tried to get into the BIOS but the keyboard wasn't responding so I powered down the system then powered it back up and there was no video. I've cleared the CMOS, tried another video card in different PCI slots, reseated the CPU and the power to the board, still no video. Did the BIOS flash corrupt the CMOS chip?

Yes could be the problem. Flashing bios is always!! a risky business. Best you can do is check all the connections, ie reseat all cards and memory. If that doesn't work looks like new motherboard time unless you can get a new CMOS chip to fit the board.

Where I can find last BIOS version for my P5VD2-NVM/S?

Click on Start and then Run.

In the text box in the Run window, type msinfo32 and click OK. This will open the System Information program.

When System Information first opens, it defaults to the System Summary, a short list with some of the most important information about your computer system listed.

On the right side of the program, locate the BIOS Version/Date entry.

This field contains the BIOS version that is currently running on your motherboard.

This field may also contain additional information such as the BIOS date, BIOS manufacturer, motherboard manufacturer and the motherboard model number.

Note: If the BIOS date is shown, it can be useful in determining the current BIOS version from a motherboard manufacturer's website if the version is not clear here.

Write down your existing BIOS settings so you can restore them after you've flashed the new BIOS firmware.

Determine the correct BIOS firmware that you need for your computer.

Check your computer manufacturer's website for this information.

If you have a custom-built system, check the motherboard manufacturer's website for the latest BIOS firmware.

Download the latest BIOS firmware specific to your computer.

Some manufacturers provide custom software that initiates the update through your operating system; others provide a third-party application that allows you to flash the BIOS through DOS.

Run the installer or executable file that you downloaded.

Alternately, if the BIOS firmware update is handled via your operating system, simply click "Update," "Write," "Confirm" or a similarly-named button.

If you are prompted for an installation CD, insert the media into your disc drive.

If the CD contains an "autoexec.bat" file, the BIOS will flash automatically when you restart the computer.

While the BIOS flashing procedure varies, nearly all manufacturers provide detailed instructions for completing the task.

Turn off your computer.

Wait about one minute and then reboot.

On some systems, the flash update will restart your computer automatically.

As your computer reboots, go immediately into the BIOS setup menu and look for an option to "Restore Defaults" or "Load Fail-Safe Defaults."

This will be on the main page or the last page of a tabbed menu.

Navigate using the arrow keys on your keyboard and follow all on-screen instructions.

When finished, save your new settings and then exit BIOS.

Your computer will load the operating system.

hope this helps

I have a K8N-VM mobo. I flashed it up the other day. Initially it worked fine but when I tried to go into the bios settings it hung. I rebooted and got the Bios Checksum error screen. I shut down and...

Reboot, go into the BIOS despite the error message then lower some settings below default values. Save and restart - if you got the same error message again then the BIOS chip is no longer powered correctly, the motherboard is dead.

This motherboard has been working flawlessly for months. Suddenly all entries in device manager starting with "system management bus" have the yellow Bang! symbol. The all say they need the driver...

This motherboard may need to have the firmware in the bios re-flashed with the latest version.
All functions in the motherboard need the bios. If the bios is corrupted, you will have problems similar to what you have stated.
Look up the bios on the Internet for the version of motherboard and the bios.
Re-flashing with the wrong version will ruin the motherboard's bios. Be sure you have the correct version and re-flash the bios.
Then try the board.

Flashed bios wont boot ga-ep43-ud3l

Seems like your bios update failed, was corrupt, wrong version or was interrupted.

It's very difficult to recover from a failed bios flash , but if you are lucky you can try clearing cmos then take the battery out overnight. Then reinstall battery and do a HARD BOOT.

If that does not work try this site and read recent comments.

Good luck,

Can't boot after upgrade bios f6

If you flashed the BIOS and it stopped for whatever reason or you flashed the wrong BIOS version, there is nothing that you can do except to replace the BIOS IC.
  • If the system has a boot block to restore the original BIOS, use it. Refer to your motherboard documentation.

  • If not, you will need to contact the system or motherboard manufacturer for a replacement.

How can I change the motherboard boot logo


The EPA logo and the Fullscreen logo all are stored in the bios. That is the update 
you download from the manufacturer's website contains both the logos in it. So if you mod the bios update and then apply the patch the next time when you boot your computer you will see the new logo.


Software Used

Winflash 1.51
Award Bios Editor 1.0
CBROM 2.15

The mods are in two sections.  If you only want one or the other, just skip to that section.


1. Make Sure the motherboard uses the Award Bios.

2. Either Download the new Bios from the Manufacturer website or get it from the system Bios directly by backing it up.  For backing up and updating bios, I use WinFlash 1.51 (there might be a newer version, I just stick with what works!).

3. Now we have the bios file on disk. Now make a new bitmap image with any of your favorite imaging software. Make sure that the final bitmap image you have created is 640*480 and 256 colors.

4. Now use the CBROM Utility to change the boot logo in the bios file.
This is done by using Command Prompt

c:\bios>CBROM215 bios.bin /logo logo.bmp

5. Now to check whether the bios file was updated correctly. Run the Award bios editor. (make sure the dlls in the plugin directory are moved to the folder with awbedit.exe)

6. Load the bios.bin in the Award bios editor and check in the left hand list for Fullscreen Logo and that it does show your logo.  If okay your bios is now ready to be flashed.

7. Now use Winflash utility, load the bios.bin and click on update .

8. Reboot the computer and the bios logo is changed.

EPA Logo:

Procedure for the EPA logo is just same except the few things.

Image size is : 138*84 16 Colors and 72 pixels/inch

Command for adding to bios file is : c:\bios>CBROM215 bios.bin /epa epalogo.bmp

When you check for the EPA logo in the Award Bios Editor, the colors will not be same as those that you choose but when you flash the bios and reboot, it will show the original colors.


Never try to flash bios without a uninterruptible power supply (UPS).
Close all the programs before flashing from Windows.
ALWAYS wait for flash program to notify you for reboot, DO NOT EVER EVER reboot when you think it is ready or taking too long.  Mucking up the flash CAN MAKE YOUR MOTHERBOARD GARBAGE!!!  You have been warned!!

I hope that this helps,
