It's designed to be the fastest (also the smallest, but that's not the main aim) SeaBIOS that is just enough to boot a Linux kernel using the -kernel option on i686 and x86_64. This commit does not modify the -kernel option to use this. You have to specify it by doing something like this: -kernel vmlinuz -bios bios-fast.bin Signed-off-by: Richard W.M.
