The OPs processor could very well be named as it is and still be x86_64 capable. The right place to look is a bit further down: >> flags : fpu vme de pse tsc msr pae mce cx8 apic mtrr pge mca >> cmov pat pse36 clflush mmx fxsr sse sse2 syscall nx mmxext fxsr_opt >> 3dnowext 3dnow up pni lahf_lm ts fid vid ttp tm stc This part lists all the features of the CPU and the one that means x86_64 is callled "lm" (long-mode). This Semperon CPU should not be able to run an x86_64 linux dist. /Peter -------------- next part -------------- A non-text attachment was scrubbed...
