Adam? It works fine on such machines, I tested it on my Pentium III: [atkac@drtic ~]$ cat /proc/cpuinfo |egrep '(model|flags)' model : 8 model name : Pentium III (Coppermine) flags : fpu vme de pse tsc msr pae mce cx8 mtrr pge mca cmov pse36 mmx fxsr sse up libjpeg-turbo code uses the cpuid instruction and dynamically selects the best routines (SSE2/MMX/standard FPU). -- Configure bugmail: https://bugzilla.redhat.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug. _______________________________________________ package-review mailing list package-review@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/package-review
