-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.

- Say Y here if you are building a kernel for a desktop, embedded
- or real-time system. Say N if you are unsure.

Find out whether you have a PCI motherboard. PCI is the name of a

your box. Other bus systems are ISA, EISA, MicroChannel (MCA) or
VESA. If you have PCI, say Y, otherwise N.

- information about which PCI hardware does work under Linux and which
- doesn't.
