Many times over the years I've gone to looking to d/l a boot disk but for some reason they don't provide one even though for most people bios flashing is the only reason they'd need the project. If that's the case and you do have a floppy another way of doing this would be to use dosemu for creating boot floppy with bios update. I only tried to reflect my situation where I had linux (and only linux), had no floppy, and still wanted to flash my bios, nevertheless.

A lot of vendors ship compressed floppy images as exe file (how to extract bios upgrade from there if not by using dosemu). Yes, it's true that in the end you flash the BIOS from the Free DOS, but why's that so important?

The title was misleading only to those who look for problems.

I have Linux and I cannot flash my BIOS via conventional methods.

At least until we achieve the World Domination(tm) and thus get to compile our own BIOS-es from source. I was just in this audience: no windows, no dos, no floppy drive.

I roughly knew what to do, but did not know where to find freedos, rarely edited iso images, never burnt a bootable cdrom before, this article saved me a few hours of research and trial/error. No, installed OS is not affected with a BIOS update.

In other words: If the mount went without errors, copy BIOS flash utility and new BIOS image to the mounted floppy disk image.

You'll probably have to unzip the archive you downloaded from your motherboard vendor site, to get to those two files.

Well, you theoretically could have some trouble after the BIOS update if some feature in the new BIOS is incompatible with your setup.

But that is VERY unlikely, so IMHO you can effectively ignore that outcome.

Notice that on some modern distributions, Step 4: Reboot, flash, reboot, enjoy your new BIOS Finally reboot your machine, make sure that your CD drive is first in the boot sequence, and then run your BIOS upgrade procedure when the CD boots.
