How to Update Your Dell BIOS with Phoenixtool Ver211 21
If you have a Dell computer and want to update your BIOS to the latest version, you may need to use a tool called Phoenixtool. Phoenixtool is a software that can extract, modify, and flash Dell BIOS files. It can also update some modules inside the BIOS, such as the Intel Rapid Storage ROM, which can improve your system performance and compatibility.
In this article, we will show you how to use Phoenixtool Ver211 21 to update your Dell BIOS with ease. Follow these steps carefully and make sure you have a backup of your data before proceeding.
Step 1: Download Phoenixtool Ver211 21 and the latest Dell BIOS file
The first step is to download Phoenixtool Ver211 21 from this link [^1^]. This is the latest version of the tool as of April 2023. You will also need to download the latest BIOS file for your specific Dell model from this link [^2^]. Make sure you choose the correct file for your system and save it in a folder on your desktop.
Step 2: Open Phoenixtool Ver211 21 and load the Dell BIOS file
The next step is to open Phoenixtool Ver211 21 and load the Dell BIOS file that you downloaded. To do this, double-click on the Phoenixtool.exe file and wait for it to finish loading. You will see a log output telling you it found the public key. Then, click on the Advanced button and enable/disable options to match the image below:
Note: These may not be the appropriate options for your setup as you may need it to alter the ACPI tables for it to work for you. With some systems, this is not the case. You can also test without modifying any modules and check the hash against the .hdr file that's created and the SLIC.hdr file that's created to determine if it's the same without modifications. This will tell you Phoenixtool is properly rebuilding the original BIOS.
Step 3: Identify and update the module you want to change
The third step is to identify and update the module you want to change inside the BIOS. For example, if you want to update the Intel Rapid Storage ROM, you need to find the file named 20_22.ROM in the dump folder that Phoenixtool created. You can confirm this by looking into the contents of the file using a strings application or a hex editor and seeing the Intel Rapid Storage string inside of it:
Once you have identified the ROM you need to update, go to this link [^4^] and find the ROM that you'd like to change it with. In this case, we used Intel RST RAID ROM v18.104.22.1687 which appears to be the recommended one for Raid 0 configurations. Note: You should always check if your chipset is supported by the ROM you choose and proceed with caution as you may risk bricking your system if you use an incompatible ROM.
Once you have the file, extract the .bin from the archive and replace your ROM file (in this case 20_22.ROM) with the updated ROM. Delete 20_22.ROM, paste the new bin in the folder and rename it appropriately.
Step 4: Flash your modified BIOS using Phoenixtool Ver211 21
The final step is to flash your modified BIOS using Phoenixtool Ver211 21. To do this, press the Go button within Phoenixtool and wait for a popup indicating you're able to modify the files within the DUMP 061ffe29dd
