I spent a lot of time trying to figure out the best way to upgrade the BIOS on a Dell Poweredge 650. I had multiple problems because I didn’t have a floppy drive to use at first and the fact that the PE650 is an older Dell server model. Since I didn’t have a floppy drive to test with initially I attempted to use the Dell System Build & Update Utility however I was unable to ever get it working properly. Initially the problem was simply getting the tool downloaded. Finally I decided to order a floppy drive and below are instructions to upgrade the PE650 using a floppy disk.
