Yes, I am trying to avoid a bios disaster. However, there are some changes in the bios that seem advisable such as one that prevents CMOS battery bulging problems. So, I would like to perform an update to bios version A23. I thought there might be someone out there who is running version A23 with a Linux installation. This warranty on this laptop expired a long time ago. So, Dell is of no help--though they may know the answer to my question.
I use Linux exclusively. To update a Dell BIOS I use a bootable FreeDOS thumb drive. Just download the newest BIOS file and copy it to that thumb drive. I've done this on probably 15 Dells. If you need more details I'd be glad to provide them.
I don't have an E7450 yet (a used one is coming), but (unless something has changed with this model) you're not stuck with newest BIOS, you can always downgrade. I've been using Linux exclusively for about 17 years now and I almost exclusively use Dells, and in all that time I've always updated the BIOS to the newest one available. One time (only) did I then downgrade to an older BIOS (turned out the BIOS wasn't the issue) so I upgraded again. Here's the list of older BIOS' for the E7450. All available to d/l.

Welcome to the Dell Community @Ramdy
That is a good question but limited to a very select few that would know the answer.
What BIOS version has the best advantages and the least conflicts while running Linux Mint???
I am not sure about that???
But you are correct the version is A23.

You could click on "DOS" as the operating system.
Then follow the "DOS" installation instructions.
I use a bootable USB drive for doing BIOS updates.
