不要钻牛角尖，没有好处。

这叫钻牛角尖？？？？

这叫学习！！！
你不知道自己的处理器是多少位的怎么装fc？

这个完全没有必要细究。说是钻牛角尖也不算。

当今主流的PC用CPU大多是32位的。16位的CPU估计在工控机或嵌入式上还有。64位的PC用CPU只有AMD有（除非你是Intel的人。）

另外，如果你是迅驰的BB，那么肯定是32位的。
所谓迅驰，是Intel P-M的CPU＋Intel主板＋板载ipw2100无线网卡的统称。
对linux来说，现在完全可以驱动起来。没有需要仔细辨别CPU位数的必要。

如果真想学习，应该自己去查资料

另外，linux一开始就是针对32位CPU的

自己买的车, 却在问"怎样才能知道我的发动机是几缸的?"

我用的是ibox-final-2.0，在EM64T的机器上运行i386的内核，/proc/cpuinfo是：

不知道如何能看出来？
另外，dmesg里也没看出来有CPU的信息：

dmesg 如果太长，前面的部分就被丢弃了，所以还得看 /var/log/dmesg

echofrompat

版主大人，我贴上的就是/var/log/dmesg里的信息。
其实应该在/proc/cpuinfo里看的。
笨笨地到google上搜一搜，找到以下讯息：
http://lists.debian.org/debian-amd64/2005/02/msg00117.html
http://www.paradicesoftware.com/specs/cpuid/index.htm

/proc/cpuinfo里的flags告诉我们CPU的特性。这个可以用来标识不同的CPU。

flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe lm pni monitor ds_cpl cid xtpr
bogomips : 6307.84

又在www.intel.com/design里看了Intel CPUID的介绍，现在总结如下：

mmx sse sse2 这些都是Pentium的标识，分别代表了多媒体处理，和SSE(Streaming SIMD Extensions)。这里，SIMD可能是Single Instruction Multi-Data的意思(俺记不太清楚了)。这些特别的指令集在其它非Pentium上是没有的。
ht(Hyper-Threading)，lm (Long Mode)都是EM64T机器的特性，其中lm使EM64T具备了操控64位内存的空间的能力。
pni(Prescott New Instructions)说明我用的是Prescott，是由P4进化而来的x86_64类型的CPU。
monitor ds-cpl cid xtpr这些都是ECX寄存器里的特征标记，说明我用的是EM64T的CPU，详细的说明，大家到Intel的网站上去看好了。

有人用AMD64的CPU吗？我这里没有AMD的CPU，没办法看cpuinfo。。。

沸魂

不知安腾有64位版的没有

不然INTEL都是32位的
AMD除了ATHLON64以外都是32位的

PS:知道CPU的型号也就知道知道是多少位的了,这个查一下就知道了啊~~
