The BIOS update of the graphics card, like the BIOS update of the motherboard, is gradually being welcomed by home improvement groups. Fix the errors in the map and use your potential. By updating your graphics card’s BIOS, you can make your system as stable as possible.
Nevertheless, graphics BIOS flash carries latent risks. How can we minimize these dangers?
NVIDIA and ATI cards are two commonly used graphics cards. The following preparation is required before the BIOS flash.
First find the graphics card model.
Graphics card BIOS differ due to different brands and models, in general they cannot be used universally. Pay attention to the respective model, e.g. For example, if the memory is SGRAM or SDRAM, 8 MB or 16 MB, PCI or AGP version, there is a TV output … Otherwise, the card may be badly wrong or started by executing an incorrect BIOS file even scrapped.
Second, you can find the version of the original BIOS; Check the manufacturer’s website for BIOS details and download a compatible and newer BIOS file for the graphics card.
Third, check if drivers are required.
Fourth, a copy of the NVFLASH utility (used in the NVIDIA BIOS flash, you can download it from websites and use it to restore the current graphics BIOS) or a copy of the FLASHROM utility (used in the ATI BIOS flash).
Fifth, make a boot disk. All graphics card BIOS flashes run more reliably under DOS, so we need to create a DOS boot disk. Then copy the downloaded BIOS file and the file NVFLASH.exe (for NVIDIA BIOS Flash) / FLASHROM.exe (for ATI BIOS Flash) to the hard disk.
When the preparations are complete, proceed to the next step by updating the graphics card BIOS.
Try to keep the power supply running throughout the process to ensure smooth operation.
NVIDIA graphics adapter BIOS Update
1. Make a backup copy of the current NVIDIA graphics card BIOS. Use the BIOS flash disk to start the computer and at the command prompt type “A:” “nvflash.exe -b backup.rom” and press Enter. The NVFLASH utility restores the current NVIDIA graphics BIOS to the flash disk (backup.rom).
2. BIOS update Enter “n:” “nvflash -p -u -f (name of the new BIOS file including the file extension)” at the command prompt and press Enter. NVFLASH overwrites your old BIOS information with the new values. If you see error messages or unusual results, do not restart the system. See the following troubleshooting for instructions.
If everything seemed to be working properly, restart the system.
Depending on the BIOS version used and the graphics card, you may need to install new drivers.
ATI graphics adapter BIOS Update
3. Make a backup copy of the current ATI graphics card BIOS. Start the computer with the flash disk. At the command prompt, type “flashrom.exe -s 0 backup.rom” and press Enter. Now the FLASHROM utility restores the BIOS of the current video on the hard drive (backup.rom).
1. BIOS update At the “A:” prompt, enter “Flashrom -p 0 ***. Rom” (*** means the name created for the BIOS update file). Press Enter to write the new BIOS to the current BIOS chip. Wait a few seconds. If you do not see an error message, restart the computer. The update is successful.
Special situation, add flashing command parameter
Add the “-f” parameter
Some graphics cards encountered an ID error during the process. Try adding a mandatory update parameter “-f” to force the BIOS flash. When it is confirmed that the new BIOS file supports the video adapter ID, type “atiflash -p -f 0 ***. Rom” and then press Enter.
Add the “-atmel” or “-sst” parameter
For some video adapters with the mBGA package, the memory and the addition of the “-f” parameter cannot update the BIOS. If the BIOS chip is from ATM Company, enter “Flashrom -p -f atmel 0 ***. Rom”. If from SST Company, enter “Flashrom -p -f -sst 0 ***. Rom”.
Depending on the BIOS version and graphics card used, you may also need to install new drivers.
Since reprogramming the BIOS is not an easy task for all PC users, you should remember to restore the current BIOS before flashing your graphics card with the new BIOS version should you encounter problems later.
What to do if the BIOS upgrade fails?
Well, if there is screen glare and instability after reprogramming, is there a remedy?
We can fix this by updating the BIOS backup file to the graphics card again, just like updating the new BIOS, just to change the command line “newbios.rom” to “backup.rom”.
If the flash process fails, we have the following fixes:
1. If Windows can be accessed but the graphics card is not recognized, start the system from the DOS boot disk and write the exact BIOS into the EPROM. BIOS functions can be continued after the start.
2. Screen is black. First pull out the AGP graphics card and start the computer after inserting a PCI card. Then call the BIOS settings program on the main board, select the option “Integrated Peripherals” and change the value for “Init Display First” to “PCI Slot” “, save this setting and shutdown.
Then reinsert the AGP card at the same time, keep the PCI card connected to the monitor and restart it.
Finally, update the correct BIOS when you update the new BIOS.
3. If there is no PCI card, we can try to “work blind”. First find another computer, create an AUTOEXEC.BAT file on the DOS boot diskette and write “nvflash” (a file name of the backup BIOS on the NVIDIA graphics card) or “Flashrom -p 0 Backup” in this text file. rom “(in ATI graphics card).
After the batch file has finished editing, start the previous computer with the hard drive. Wait more than 10 seconds after reading and restart the computer. Then everything is back to normal.
If there is an EEPROM programmer, we can use it to write the correct EPROM to the BIOS.
