Updating bios with usb

This all started one day recently when I decided to upgrade two of my older Linux systems.

I have been running BOINC for several years to participate in various distributed computing environments and have been using those two computers almost exclusively as compute platforms for that purpose.

I don't know for certain what the last field is, but I think it might be a time in 24-hour format so that the last three fields represent the date and time the BIOS was compiled.

My original BIOS was version 23 and, according to the Intel website, the most current version is 120.

The third field, 0048, is the actual BIOS version level, and is what appears in the Intel web pages; if someone says you need to be at BIOS version 48, that is the number to look at.

I decided that I wanted to add more computing power to those tasks so decided to update some of my older computers rather than purchasing new ones.

After all, these are perfectly good computers with yet untapped capabilities.

Note that not all of the intervening BIOS version numbers were released to the public, but there were still 20 versions posted and 17 were more recent than mine.

So I downloaded the most recent and tried to use the F7 option at boot time to upgrade the BIOS.
