Is this a problem to anyone? It's always a bit sad to have to give up compatibility, but otoh most boxes with i386 CPUs (including Cyrixes and WinChips) are usually not that well equiped to run the bloated releases we have today anyway. Actually i386 support has already been effectively discontinued (https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=103078). Time to start looking for some small footprint distros for such boxes. > There have been some i486+ only instructions accidentally > used in the past in many C++ programs (from libstdc++-v3 > headers) and apparently nobody noticed this in RHL or > Fedora, so I assume not really many people are attempting > to revive their i386 boxes. Well, at least one person has tried to :) . > Another alternative is to change all rpms in FC3 which are .i386.rpm > in FC2 to .i486.rpm, with rpmrc: Although it might appear a bit funny at first I think this is the most consequent solution. If it's not i386 compatible it shouldn't be called so. Also have a look at https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=91933 . Leonard. -- mount -t life -o ro /dev/dna /genetic/research
