Updating the bios on a Dell PE 860 using USB

Sorry, this is going to be brief:

  1. Use unetbootin to put freedos on a USB stick
  2. Download the BIOS update from the Dell site (use the unpackaged version), copy to the root of the USB drive and rename to install.exe
  3. Boot the Dell machine to the USB stick (see previous post for details on this)
  4. When you’ve reached the FreeDOS boot menu, choose “FreeDOS Live CD with HIMEM only” (live CD only and HIMEM + EMM386 didn’t work for me)
  5. Change to the USB stick (should be “c:”)
  6. Install the new BIOS (“install”)
