How do I install the firmware update for LinkSys E900 router?

Hi,

I'm using Mac 10.7.5 and a few months back had purchased the E900 wireless router.  It has firmware 1.0.03 installed and I noticed there is a 1.0.04 update.  I downloaded the update, which is a .bin file, but I do not have a CD burner nor access to a Windows machine.  How can I install the firmware update?

Thanks, - Dave
