39 The Mappi-I is an FPGA board for SOC (System-On-a-Chip) prototyping.
40 You can operate a Linux system on this board by using an M32R
41 softmacro core, which is a fully-synthesizable functional model
42 described in Verilog-HDL.
43
44 The Mappi-I board was the first platform, which had been used
45 to port and develop a Linux system for the M32R processor.
46 Currently, the Mappi-II, an heir to the Mappi-I, is available.

231 help
232 This option reduces the latency of the kernel when reacting to
233 real-time or interactive events by allowing a low priority process to
234 be preempted even if it is in kernel mode executing a system call.
235 This allows applications to run more reliably even when the system is
236 under load.

239 or real-time system. Say N if you are unsure.

244 This enables support for systems with more than one CPU. If you have
245 a system with only one CPU, like most personal computers, say N. If
246 you have a system with more than one CPU, say Y.
247
248 If you say N here, the kernel will run on single and multiprocessor
249 machines, but will use only one CPU of a multiprocessor machine. If
250 you say Y here, the kernel will run on many, but not all,
251 singleprocessor machines. On a singleprocessor machine, the kernel
252 will run faster if you say N here.
253
254 People using multiprocessor machines who say Y here should also say
255 Y to "Enhanced Real Time Clock Support", below. The "Advanced Power
256 Management" code will be disabled if you say Y here.

328 On PCI systems, the BIOS can be used to detect the PCI devices and
329 determine their configuration. However, some old PCI motherboards
330 have BIOS bugs and may crash if this is done. Also, some embedded
331 PCI-based systems don't have any BIOS at all. Linux can also try to
332 detect the PCI hardware directly without using the BIOS.
333
334 With this option, you can specify how Linux should detect the PCI
335 devices. If you choose "BIOS", the BIOS will be used, if you choose
336 "Direct", the BIOS won't be used, and if you choose "Any", the
337 kernel will try the direct access method and falls back to the BIOS
338 if that doesn't work. If unsure, go with the default, which is
