It's probably quite a recent stepping, though. I think behavior of Cyrix 486 CPU depends on its step. I know following kind of machines: 1) No patch is needed. 2) The modifications of machdpe.c and trap.c are needed. 3) The modification of pmap.c is needed. 4) All modifications are needed. ---- KATO Takenori <kato@eclogite.eps.nagoya-u.ac.jp> Dept.
