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.
I have a development server, which is a Dell Poweredge 650, running CentOS Linux that is used for testing PostgreSQL database replication via log shipping and recently the server has been crashing after only running for a couple hours from a kernel panic. One of the things I wanted to verify is if there is a new BIOS version available but first needed to verify the current BIOS version installed. Below is information on how to determine what BIOS version a Linux server is using while the server is running.
