Using Eva's disk you don't need to worry about commands, this is what you do:

Boot into DOS and using Eva's files on a CD or Dos disk type:

backup0 (this will backup original bios on master);
backup1 (this will backup original bios slave);

update0 (updates master to Asus Top Bios)
update1 (updates slave)

If someday you need to return the cards to stock, using same disks you will type:

restore0
restore1

Simple as that...
