| |
I am working with several SMP Athlon machines, and they are all reporting the first CPUs model ID(*** called 'model name' in /proc/cpuinfo) as 'AMD Athlon(tm) MP 1800+' and the second CPUs model ID as 'AMD Athlon(tm) Processor'.
From looking at the code it seems that the model IDs are obtained using cpuid calls. Does anyone have insight into this?
Some Info: Motherboard: Tyan S2462NG CPUs: 2 Athlon MP 1800+ Kernel Version: 2.4.18-rc4
