编译64位cpu的两个问题（超线程和双核）

3rd0mit

我的版本是debian sarge
对于双核cpu,我在设置时选中了:
Processer type and featrue-->[ * ]Symmetric multi-processing support
Processer type and featrue-->[    ] SMT (Hyperthreading) scheduler support
Processer type and featrue-->[ * ]Multi-core scheduler support
结果系统监视器里还是看不到两个cpu
是否还需要加入别的选项?

我编译另一台机器的内核时，想加入超线程：
Processer type and featrue-->[ * ]Symmetric multi-processing support
Processer type and featrue-->[ * ] SMT (Hyperthreading) scheduler support
Processer type and featrue-->[    ]Multi-core scheduler support
同样系统监视器里看不到两个cpu

请教高手，应该如何设置啊？
