Y400 BIOS Update (yx00s204.exe) without OS?

My Windows install is corrupt and while trying to recover it was suggested by Microsoft that I try a BIOS update.

 

Currently, my Y400 has version 6BCN34WW (v1.05)

I'd like to upgrade to version yx00s204 (v2.04)

 

However, as I cannot get into Windows, I can't very well run yx00s204.exe!

 

How can I update the BIOS now?
