Apparently, if you build a kernel for other than i386 (say, i486), it won't run on i386 > If I missed the topic of the thread, please tell. Maybe I also know the > answer of the original question ;) Well, I was experimenting with builing packages from source and I noticed that they were compiled for i486. The rules file calls dpkg --print-gnu-build-architecture to determine the machine. I wondered why it sees my i586 as a i486. Don't confuse this with the architecture which is i386, even for PentiumII I guess.
