thinkpad 600e bios update without floppy drive

i think i should have put this in it's own post so here i go..

HELP!!!

i have the thinkpad 600e that is on bios 35 but needs to be the latest which is 36 as i want to put xp onto it.
unfortunately the bios file on lenovo site is a floppy image and the laptop has cd drive.
i downloaded the Virtual floppy drive and set it to A. i then set it to run so it shows in my computer as an actual drive. when i double click the file it goes into a sort of dos screen and seems to go fine asking me to press enter to agree with certain bits then says that there is no floppy disk in the drive.

i am lost here. i simply need a VERY exact help as i am not very computer minded and have got this far with reading these posts.

if it helps, it currently runs win2000

come on guys, surely someone can give some advice.

i have just purchased an external floppy drive but not arrived yet. it works through usb but not sure if the laptop will boot from it or if i can only use it in windows?
