Video card BIOS update, such as the motherboard BIOS update, is gradually welcomed by DIY groups. Fix the bugs in the card and tap its potential, Flashing your video card BIOS lets you have your system as stable as possible.
Nevertheless, graphics BIOS flash has latent risks. Just how can we minimize these dangers?
NVIDIA and ATI cards are two common graphics adapters in use. Before BIOS flash, these preparation is necessary.
First, get the video card model.
Graphic card BIOS are distinct due to different brands and different models, generally they are able to not be applied universally. Do focus on the specific model Polaris Bios Editor download, for instance, the memory is SGRAM or SDRAM, it’s 8MB or 16MB, PCI version or AGP version, can there be any TV output…Otherwise, running an improper BIOS file might make the card going badly wrong or even scrapped.
Second, get the version of the first BIOS; search the manufacturers’ website for BIOS details, download an appropriate and newer BIOS apply for the video adapter.
Third, determine if any drivers required.
Fourth, a copy of the NVFLASH utility (used in NVIDIA BIOS flash, you can download it from websites and utilize it to replace the current graphics BIOS), or even a copy of the FLASHROM utility (used in ATI BIOS flash).
Fifth, make a start disk. All video card BIOS flash is carried out more reliably in DOS, so we have to create a DOS boot disk. And then copy the downloaded BIOS file and the NVFLASH.exe file (for NVIDIA BIOS flash)/FLASHROM.exe file (for ATI BIOS flash) onto the disk.
Since preparations are ready, then go to another step-flashing graphics card BIOS.
To be able to allow operation go smoothly, try to keep the ability supply employed in gear in the complete procedure.
NVIDIA graphic adapter BIOS update
1. Create a backup of the current NVIDIA graphic card BIOS Utilize BIOS flash disk as well the computer and enter DOS, at the “A:” prompt, type “nvflash.exe -b backup.rom” and press Enter. The NVFLASH utility will restore the current NVIDIA graphics BIOS onto the flash disk (called backup.rom).
2. BIOS update From the “A:” prompt, type “nvflash -p -u -f (name of the new BIOS file like the file extension)” and press Enter. NVFLASH will overwrite your old BIOS information with the new values. If you see any error messages or odd results, don’t restart the system. Consult the troubleshooting below for further instructions.
If everything seemed to work effectively, restart the system.
With regards to the BIOS version you used and the video card, you may need to install new drivers.
ATI graphic adapter BIOS update
3. Create a backup of the current ATI graphic card BIOS Boot the computer with the flash disk, at the “A:” prompt, type “flashrom.exe -s 0 backup.rom” press Enter. Now the FLASHROM utility will restore the current video’s BIOS onto the disk (called backup.rom).
1. BIOS update At the “A:” prompt input “Flashrom -p 0 ***.rom” (*** means created term for the BIOS update file) hit Enter then the new BIOS will be written into the current BIOS chip. Wait for a couple seconds, when there is no error massage popping up then restart the computer. Updating succeeds.
Special situation, add flashing command parameter
Add parameter “-f”
Some graphic cards would encounter ID error during the operation, try to incorporate a required updating parameter “-f”to force the BIOS flash; When the new BIOS file is confirmed supporting the video adapter ID, input “atiflash -p -f 0 ***.rom”, and finally press Enter.
Add parameter “-atmel” or “-sst”
For some video adapters with the mBGA packaging its memory, and adding parameter “-f” is not able to update BIOS. If the BIOS chip is from ATM Company, then input “Flashrom -p -f atmel 0 ***.rom”; if from SST Company, then input “Flashrom -p -f -sst 0 ***.rom” ;.
With regards to the BIOS version you used and the video card, you may need to install new drivers too.
In respect that reprogramming BIOS is no easy job for all PC users, before flashing your video card with the new BIOS version, remember to replace the current BIOS just in case you encounter trouble later on.
What should we do when BIOS upgrading fails?
Well, then, if screen dazzling and instability occurs after reprogram, can there be any remediation?
We can figure out this problem by upgrading the backup BIOS file once again into the video card the same as updating the new BIOS, only to change the command line “newbios.rom” to “backup.rom” ;.
If flash fails, we have several fixes as below:
1. If Windows is available, but can not recognize the graphics card, utilize the DOS boot disk to set up the machine, and rewrite the actual BIOS into EPROM. BIOS features may be resumed after start-up.
2. Screen is black. Unplug the AGP video card firstly, and boot up the computer after plugging in a PCI card, from then on enter the BIOS setting program in the motherboard, choose “Integrated Peripherals” option, change the option “Init Display First” value to “PCI Slot”, save this setting and shut down.
Then reinsert the AGP card at the same time frame keep carefully the PCI card still linked to monitor, and restart.
Finally, upgrade the right BIOS as we update the new BIOS.
3. If you have no PCI card, we can make an effort to “operate blindly” ;.First, find another computer, create an AUTOEXEC.BAT file in the DOS boot disk, and in this text file write “nvflash” (a filename of the backup BIOS in NVIDIA graphics card) or “Flashrom -p 0 Backup.rom ( in ATI graphics card ).
Following the batch file finishes editing, boot up the former computer with the disk, when reading is over, await over 10 seconds, and restart the computer. Then everything returns to be normal.
