| This allows you to specify the maximum number of CPUs which this |
| kernel will support. The maximum supported value is 32 for 32-bit |
| kernel and 64 for 64-bit kernels; the minimum value which makes |
| sense is 2. |
| |
| This is purely to save memory - each supported CPU adds |
| approximately eight kilobytes to the kernel image. |

| config PREEMPT |
| bool "Preemptible Kernel" |
| help |
| This option reduces the latency of the kernel when reacting to |
| real-time or interactive events by allowing a low priority process to |
| be preempted even if it is in kernel mode executing a system call. |
| This allows applications to run more reliably even when the system is |
| under load. |

| The Extended Industry Standard Architecture (EISA) bus was |

| |
| The EISA bus provided some of the features of the IBM MicroChannel |

| 1995 when it was made obsolete by the PCI bus. |
