for thinkpad model P50
  1. Download the BIOS Update bootable CD image from Lenovo "n1eur31w.iso" (Select Windows as OS so it's available for download).
  2. Extract the eltorito boot image from the image "geteltorito -o thinkpad.img Downloads/n1eur31w.iso".
  3. Dump it on a USB thumb drive "dd if=thinkpad.img of=/dev/sdX".
  4. Boot from this thumb drive and follow the instructions of the installer.
'I guess the process is similar for almost all ThinkPads.'
  • For supermicro and others I have seen well designed bios upgrade procedures for windows users. it would be nice to have a procedure like the one for thinkpad for supermicro.
