不选这个功能，加载的模块就不能卸载 [ ] Forced module unloading [ ] Module versioning support (EXPERIMENTAL) [ ] Source checksum for all modules [*] Automatic kernel module loading 处理器类型及特性： Processor type and features ---> Subarchitecture Type (PC-compatible) ---> Processor family (Pentium-4/Celeron(P4-based)/Pentium-4 M/Xeon) ---> [ ] Generic x86 support 这一选项针对x86系列的CPU使用更多的常规优化。如果你在上面一项选的是i386、i586之类的才选这个 [*] HPET Timer Support HPET是替代8254芯片的下一代时钟处理器。这里你可以安全的选上这一选项。如果硬件不支持的话，将仍使用8254时钟处理器 [*] Symmetric multi-processing support 对称多处理器支持，在单CPU的机器上，不选这个选项会更快一些。由于超线程技术，看起来是两颗CPU，因些要选上这个选项 (1) Maximum number of CPUs (2-255) 支持的最大CPU数 [ ] SMT (Hyperthreading) scheduler support [*] Preemptible Kernel 这个选项能使应用程序即使内核在高负载时也很可靠，建议最好选上 [*] Machine Check Exception 这个选项能让CPU检测到系统故障时通知内核，一般我用组装的台式机会选这项。 < > Toshiba Laptop support < > Dell laptop support < > /dev/cpu/microcode - Intel IA32 CPU microcode support < > /dev/cpu/*/msr - Model-specific register support < > /dev/cpu/*/cpuid - CPU information support Firmware Drivers ---> < > BIOS Enhanced Disk Drive calls determine boot disk (EXPERIMENTAL) High Memory Support (4GB) ---> [ ] Allocate 3rd-level pagetables from highmem [ ] Math emulation [*] MTRR (Memory Type Range Register) support [ ] Boot from EFI support (EXPERIMENTAL) [*] Enable kernel irq balancing [ ] Use register arguments (EXPERIMENTAL)
[page_break]电源管理： Power management options (ACPI, APM) ---> [*] Power Management support [ ] Power Management Debug Support [ ] Software Suspend (EXPERIMENTAL) ACPI (Advanced Configuration and Power Interface) Support ---> APM (Advanced Power Management) BIOS Support --->
