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.

Bios update


The servers revisions were not appropriate for that product model. Flashed BIOs, if meant for another system will no longer work as the instruction set is now compromised. If re-flashing the BIOs with the CORRECT version adjusts the problem, its is worth trying.

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.

Is there a way to repair a bios after a failed update


Recovering a damaged BIOS is simply a matter of replacing the missing or damaged code contained within the CMOS or EEPROM. This is not an easy task and some computer knowledge is strongly advised if attempting this.

You can solve the problem by removing the Lithium battery on the main board, wait a few minutes, then put the battery back in and reboot.
The BIOS will detect that there are no BIOS settings, and use some default settings. NOTE...It will tell you that some settings are erratic, but at least you are now able to press DEL to enter BIOS setup.

After entering setup you will be asked to choose either "Load default fail safe" or "Load optimal settings". The latter will work most of the time. Save these settings, reboot and see whether your attempts were successful. I've seen this type of boot failure on many machines and in case of bios update failure, this has worked 90% of the time.
If, by chance it does not work at once, try to keep the battery out a little longer, and short-circuit the + and - pins of the battery socket.

When you do get some life back into your PC don't forget to check that you indeed flashed the correct BIOS version that belongs to your motherboard. Maybe you flashed just a slightly different version. If so, find the correct BIOS version even if your PC seems to work after following the above steps, find the correct BIOS version and reflash.
I WISH YOU LUCK!

Black screen acer aspire 4315, changed screen & inverter but still no joy any help please.


If the screen is black and the power light & fan still work....try this:

ASPIRE ONE BIOS FLASH RECOVERY

First format an USB stick with FAT.

Download the latest BIOS, and put both FLASHIT.EXE and the BIOS file in the root directory of the stick. Rename the BIOS file to ZG5IA32.FD, that's important. Do not remove the USB stick.

Turn the AA1 off, make sure both battery and AC adapter are connected. Press Fn+Esc, keep it pressed and press the power button to turn the AA1 on. Release Fn+Esc after a few seconds, the power button will be blinking. Press the power button once. The AA1 will now initiate the BIOS flash, do not interrupt it under any circumstances. After a while the power button will stop blinking, and the AA1 will reboot shortly after. Wait patiently.

The BIOS has been flashed and all settings reset to default.

If for some reason you made a mistake during the procedure and it doesn't reboot by itself wait 5 minutes before turning it off, just to be safe that it isn't still flashing the BIOS.

Flashed bios wont boot ga-ep43-ud3l


Hi,
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,

SAHARA KN1 LAPTOP BIOS FLASH


flashing the bios is a tricky thing to do. basically you will find the file ( i do believe it is a .bin file) , u save on a CD along with an executable file, once you rebooted the computer, it will update it automaticall. some you might have to run the program, pointe it to the bin file, and tada, flashed. try this utility (SIW)
it will tell you what is the BIOS version, among of tons the other info. the utility is free.
there are other methods of flashing, but be careful, you try the wrong thing, and you motherboard is bye bye.

How can I change the motherboard boot logo


Hello,

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.

***BEWARE A BAD FLASH CAN RENDER YOUR MOTHERBOARD USELESS****

Software Used

Winflash 1.51 ftp://ftp.ecs.com.tw/driver/bios/flash/winflash151.exe
Award Bios Editor 1.0 http://sourceforge.net/projects/awdbedit/
CBROM 2.15 http://www.biosmods.com/download/award/cbrom215.zip



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

FULLSCREEN LOGO

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.


*****PRECAUTIONS*****

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,
Ken
