QBoot is not meant for use in production; SeaBIOS actually is just as fast if you configure it right. > Do you have any opinion for the topic? I honestly don't like the idea. Linux patches itself a lot, which makes the memory savings minimal (if they exist at all). What is the decompression time for a kernel that is compressed with LZO? Paolo
