Flashing bios using a usb drive

If you are like me where most PC run's linux and has no optical drive.  I saw the following steps around the net to be helpful.

1. Get the bios update iso
2. Get 'geteltorito' and extract the boot image from the iso

   $ wget 'http://www.uni-koblenz.de/~krienke/ftp/noarch/geteltorito/geteltorito.pl'
   $ perl geteltorito.pl biosupdate.iso > biosupdate.img
   

3. Copy the image to the usb thumdrive

$ sudo dd if=biosupdate.img of=/dev/usbthumdrive bs=512K
