Any 32-bit x86 kernel should work on an AMD Opteron machine. The only question is whether all drivers are supported. Red Hat 7.2 might not have support for all the hardware that is in an AMD Opteron ystem. > I know someone will want to know why I would want to, so here is the > explanation.

SuSE Linux 8.2/x86 works on AMD Opteron systems and I guess current Red Hat distributions do work also, Andreas -- Andreas Jaeger SuSE Labs aj@suse.de private aj@arthur.inka.de http://www.suse.de/~aj
