Well I tried installing squeeze in a qemu VM emulating a 486. It worked fine there. But qemu is emulating a 486DX4, which supports CPUID. If your 486 is older if probably does not have the CPUID instruction. The place grub is blowing up appears to be the test suite which uses qemu-system-i386. So my suspicion is that it is actually qemu crashing, not grub, and that your best bet would be to just not run the test suite. The compile almost certainly worked fine. Simply uninstalling qemu whould make it not try to run the test based on the debian/rules file, although debian/control considers qemu a built dependancy. So you probably have to use -d with dpkg-builcpackage to make it ignore the missing dependancy. Or edit debian/rules and simply set the with_check variable to no. I can't find anything that says if qemu should run on an older 486, probably since those usually didn't have enough memory to make that worth the bother and they are too slow. Maybe no one had ever tried it before. -- Len Sorensen _______________________________________________ Grub-devel mailing list Grub-devel@gnu.org https://lists.gnu.org/mailman/listinfo/grub-devel
