My kernel still doesn't boot completely, but it runs now correctly calibrate delay loop (0.59 BogoMIPS, isn't it great? ;) since the timer interrupt is working. According to the "release early, release often"-mantra, I want now to send some patches to the list. Do you want to have the Atari bootstrap patches in this mailinglist? I'm asking because bootstrap is not (anymore) part of the kernel sources... The next question would be whether you want to have a single head.S version for the Atari ST-nommu platform or a merge with the current arch/m68k/kernel/head.S. The head.S I use does not use much code from the "classic" head.S and is for sure easier to read due to its small size. Best regards, Matthias
