Step 3. The guide will be updated to reflect this change. As usual, writing it was trigerred by many, many people asking the same questions about this procedure over and over again, on this forum. I used to have a text file with the instructions and copy-paste an answer each time, but that takes up unnecessary space on the server So I decided to centralize the information in one place, namely here, and then link to this page every time somebody asks how to update their BIOS.
When should you update the BIOS? The BIOS should be updated only if the update is needed. For every BIOS update that you are considering, you should first check the list of changes and bugfixes on support.
If some of those changes solve issues that you have been having e. If none of the changes are relevant e. A word of caution A failed or interrupted BIOS update process almost always means death for the computer. For this reason, never ever interrupt a BIOS update that is already in process. For the same reason, have a good amount of charge in your battery when starting the BIOS update utility more than 10 minutes worth of it.
In that way, you will not depend on the AC supply which might run out just in the critical few seconds. BIOS files are specific to a given type of notebook. Even if the machines are superficially identical like the ASUS V1Jp and ASUS V1J, for instance , with the same basic components, details in the motherboard and various low-level controllers that you might not even know exist might be different, leading to different necessary BIOS code. The WinFlash utility in Windows.
Some of the steps are common between the three procedures, so I list them only once. The order in which I list the procedures is not arbitrary. This is because EasyFlash does not require any operating system be it DOS or Windows , nor any additional software where bugs might creep in and ruin the process.
This might be necessary sometimes. Worse, new bugs might appear, although that rarely happens. Preparing the update It is not necessary to "uninstall" anything from the computer, since the BIOS is just a chunk of flash memory KB in size on a special chip on the motherboard. This memory will be erased and rewritten in the update process; the process, once started, takes on the order of 10 to 30 seconds including erasing the old BIOS, writing the new BIOS, and verifying it.
You only need to download the BIOS file, i. This can be done from the ASUS support page. Navigate to support. Click your model number from the search results, and then click on the BIOS tab. Download the version you need. Unzip it to obtain the BIOS binary, which is directly usable by the flash utility.
Place the unarchived BIOS file somewhere on the harddrive, e. The following sections describe in detail how to update the BIOS, using three different routes. It is the safest because it does not require any operating system be it DOS or Windows , nor any additional software where bugs might creep in and ruin the process. EasyFlash should start. Confirm starting it by pressing Y if requested to do so. The utility will display in the top-left corner of the screen the model, version, and date of the current BIOS installed on the computer.
Select the drive where you saved the BIOS from the list of drives to the left of the screen, e. Then, navigate to the folder with the BIOS file, e. It is possible that drive letters have changed w. Select the BIOS file. The utility will display the model, version, and date of the BIOS file to the top-right of the screen, and ask you to confirm overwriting.
So you can use it just as easily for downgrading the BIOS. Before continuing, check that the model number is correct, and that the version is the one you intended to write. Wait patiently, it will be less than a minute. If all goes well, a message will be displayed announcing a successful operation, and after a few seconds the computer will reboot.
This will be a ZIP file. EXE on this partition. Copy the BIOS file in the same place. Burn it to a CD preferably rewriteable, such that you can reuse it afterwards. To navigate to a different drive in DOS you just type the name of the drive, e. To change directories, use cd e. Remember the location of the BIOS file, and its exact name, e. The utility will start, and will display the model, version, and date of the current BIOS in the computer.
You will be asked to type in the location of the BIOS file; you should have written this down at step 3 above. Type it down, e. Press Enter. The model, version, and date of the new BIOS file will be displayed. Also, if the BIOS is older than what you currently have, you will be asked for confirmation that you really wish to write the older version.
Confirm in order to downgrade the BIOS. Oh well. If all goes well, a message will be displayed announcing a successful operation, and you will be asked to press a key to reboot. This should however be a last resort.
The application is more poorly written than either EasyFlash or AFLASH, and there are many more things that could go wrong in Windows for instance, Windows can crash for completely different reasons, leaving you with a half-finished update and a paperweight in the shape of a laptop. For newer models, there might be no utility for XP. Even for older models it might have been removed from the website. You will need to change the number in dlsvr02 for other continents in the worst case, try them all from 01 to The file you downloaded will be a ZIP archive of the installation kit.
Unzip it, and install the software run setup. Start WinFlash from the Start menu. If you wish to downgrade, the start procedure will be a bit more involved.
Navigate to the directory where WinFlash was installed. Return to step 1. Click the Flash button. If all goes well, a message will be displayed announcing a successful operation, and you will be asked to press a button to reboot. The BIOS will then detect that it has been changed and load the defaults for all the options. Hoping this helps, sincerely yours, E.
