Upgrade The BIOS On A Dell PE650, Upgrade Poweredge 650 BIOS

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.

In this example I was upgrading a Dell PE650 from BIOS version A04 to BIOS version A05.

Upgrade Dell Poweredge 650 BIOS Using A Floppy Disk:

  1. Download A05 Floppy Disk App: Visit the Dell BIOS FTP site in a browser by clicking here. Locate the PE650-BIOSA05.EXE file, right click it, and save as.
  2. Launch BIOS Floppy Tool: Now insert a floppy disk into the floppy drive on your computer and double click the PE650-BIOSA05.EXE file to launch the Dell application which will display similar to the example image below.

  3. Format Floppy With BIOS: Now click the Continue button to format the floppy disk with the Dell BIOS as shown in the below example image.

  4. Reboot Server: Now insert the floppy you have just created into the PE650 floppy drive. Modify the BIOS to boot from the floppy drive and then reboot your server. During the boot process the server will display that it is booting into MS-DOS as shown in the below image.

  7. Verify BIOS Version: Once your server is back online you can verify the BIOS version from Linux by using dmidecode as shown below.

    1. [root@cent1 ~]# dmidecode -s bios-version
    2. A05
    3. [root@cent1 ~]#

The BIOS on your Dell Poweredge 650 has now been upgraded from its previous version, which in this example was A04, to Dell PE650 BIOS version A05.
