Different companies have different names for their Diagnostic Tools, example- Vantage for Lenovo, Dell System Software (DSS) for Dell, HP System Utility for HP, and so on. System Utility, also known as Diagnostic Tool is a vendor software in computers. This undoubtedly is the easiest and probably the safest way to update your BIOS. Now without waiting any longer let’s take a deep dive in the above mentioned methods. *Note- I am using a Lenovo product for this article Using the UEFI Tool…(just how engineers do it!).System Utility supported by your computer vendor.There are a couple of different ways to update BIOS on a system but here we are going to focus on just 3.

BIOS code is stored in ROM, making it non-volatile in nature.

Unlike other things, BIOS is not stored on hard drives but on a chip which is soldered down to the motherboard.

It is a non-volatile firmware used for initializing hardware on the system during the boot up.

BIOS stands for Basic Input/Output System.

But if you are careful enough and follow manufacturer’s instructions, you can save yourself from burning a hole in your pocket.īefore moving forward to the actual article let’s have a quick look at this chip called BIOS.

AMI-specific features like NCBs, ROM_AREA structure and other things like that can't be implemented by me because of the NDA I have.You might have heard people saying how dangerous it can be to update BIOS.

If someone wants to write an unpacker for such crappy files - I will be glad to use it.

The program is meant to work with BIOS images, not some vendor-specific BIOS update files, that is why some of that update file either cant be opened at all or return errors on reconstruction.

It's on my high priority features list, so I hope it will be corrected soon.

Some images may not work after modification because of no FIT table support implemented yet.

Some images has non-standard calculation of base address of TE images, so the program can rebase them incorrectly after modifications.

Don't rush it, because reconstruction process can also generate some usefull messages, which will be lost if you open the reconstructed file immediatelly. If anything goes wrong on the reconstruction, an error will pop up, otherwise the program will prompt if you need to open the reconstructed file. After you've finished the modifications, you need to initiate image reconstruction using Save image file command from the File menu.
