React to some Viagra spam to solve that problem

If you have another computer you can also do a PXE of a freedos image to which you copy the firmware and update program. Nowadays i first have to resize the standard floppy image though (since the firmwares are getting so damn big). Then leave that setup around and simply update your floppy image whenever you need to do a new firmware upgrade, select PXE boot in your boot setup and do the update..
