Hi, What's the most comfortable way to switch between normal and fallback images in LinuxBIOS on AMD64. I was using lxbios from http://www.llnl.gov/linux/lxbios/lxbios.html But when changing the parameters to Normal, the next boot LinuxBIOS still says "Invalid CMOS LB checksum" and it sets "boot_option" back to Fallback.
