How to Update Dell BIOS

There are many reasons why you might want to update your BIOS. Maybe you want to update to a newer processor that requires a more recent BIOS revision or maybe you are having some system crashing issue that is mentioned in a BIOS release notes and you want to give it a shot to see if it will fix it. Either way, it is best to take care when dealing with the BIOS because you can easily brick your system. In this guide I will show you how to safely update your BIOS so you can move along with your computing needs. The first step is actually locating the BIOS revision that you are interested in and finding it on the Dell support site. You will want to click choose from all products as shown boxed in red

Then navigate to the specific model of computer/server you are trying to flash. Once you click that you should see a tab that says "Drivers and downloads" along the left side. Then you will see a dropdown that includes a BIOS option. You can click download directly from that dropdown for the most recent version or you may click "View details" and read the release notes as well as look at past releases to see what other changes have been made. One thing to note is that many systems cannot be flashed if they do not have a processor or memory installed so if you are planning on using a processor or memory that does not have support on the current BIOS revision then you will have to either borrow from a friend who has an older item for you to flash with or double check that the system you are installing into has an updated BIOS. After you have determined which BIOS version will best work for you download it and put it onto a bootable USB drive. Once you have that arranged restart the target system with the USB drive plugged in. Hit F12 while booting and choose to boot from the USB drive. Once that has booted you should see a command prompt. Once you are there type down the exact file you downloaded and hit enter. This should open up the program and give you some prompts and guide you through the rest of the process. Make sure you allow this process to run completely or you may brick your system. This can take several minutes so make sure you have consistent power, maybe even put your system on a UPS during this process if it is not already on one and don't turn the system off while it may still be doing anything. Other than those considerations though the process should be pretty painless. bios flash dos
