If you take only the normal kernel into > account that will be an 80386 processor. Minimum for an x86 kernel is about 2Mb and 386 CPU. The 8086 subset kernel isn't really "Linux", its more an escaped insanity. For non x86 you need a bottom end mmuless 32bit processor and a couple of Mb. There are folks driving the size down (the -tiny patches) because 2Mb for the entire system is still too large for some users. Alan
