Updating bios with usb

Rated 4.3/5 based on 974 customer reviews

First, my BIOS version did not actually support F7 at boot time despite the fact that the option did appear on the BIOS screen.

Second, a very obscure response to another user indicated that not all BIOS versions would install directly, and it would be necessary to install multiple BIOS revisions in sequence.

The motherboard documentation—yes, I download and keep it—translated that as meaning the system had a memory error.

Of course, it was perfectly good memory right in the middle of the spec for the new processor.

That failed and the system just locked up when I tried that.

Most sysadmins also would agree that "if it is not broken, don't fix it." Upgrading BIOS just to get to the latest level is counter-productive in terms of the time it takes, but also can cause problems that did not previously exist. And that can be a problem for those of us who don't use Windows in any form, like me.

At this point, I could not get to the BIOS to do any configuration so I removed the new CPU and put the old one back in.

This at least allowed the system to boot and let me get to BIOS to check the BIOS version level and, using the Intel support website, found that to be many levels behind the most current.

There is another way to locate the BIOS level from the Linux command line and I rebooted into Fedora 25 and used the dmidecode command to locate the current BIOS.

The -t option specifies the type information to be displayed, in this case, type 0 is for BIOS information.
