52 The Mappi-I is an FPGA board for SOC (System-On-a-Chip) prototyping.
53 You can operate a Linux system on this board by using an M32R
54 softmacro core, which is a fully-synthesizable functional model
55 described in Verilog-HDL.
56
57 The Mappi-I board was the first platform, which had been used
58 to port and develop a Linux system for the M32R processor.
59 Currently, the Mappi-II, an heir to the Mappi-I, is available.

355 On PCI systems, the BIOS can be used to detect the PCI devices and

357 have BIOS bugs and may crash if this is done. Also, some embedded
358 PCI-based systems don't have any BIOS at all. Linux can also try to
359 detect the PCI hardware directly without using the BIOS.
360
361 With this option, you can specify how Linux should detect the PCI
362 devices. If you choose "BIOS", the BIOS will be used, if you choose
363 "Direct", the BIOS won't be used, and if you choose "Any", the
364 kernel will try the direct access method and falls back to the BIOS
365 if that doesn't work. If unsure, go with the default, which is

278 ---help---
279 This enables support for systems with more than one CPU. If you have
280 a system with only one CPU, say N. If you have a system with more
281 than one CPU, say Y.
282
283 If you say N here, the kernel will run on uni- and multiprocessor
284 machines, but will use only one CPU of a multiprocessor machine. If
285 you say Y here, the kernel will run on many, but not all,
286 uniprocessor machines. On a uniprocessor machine, the kernel
287 will run faster if you say N here.
288
289 People using multiprocessor machines who say Y here should also say
290 Y to "Enhanced Real Time Clock Support", below. The "Advanced Power
291 Management" code will be disabled if you say Y here.

309 This allows you to specify the maximum number of CPUs which this
310 kernel will support. The maximum supported value is 32 and the
311 minimum value which makes sense is 2.
312
313 This is purely to save memory - each supported CPU adds
314 approximately eight kilobytes to the kernel image.

337 Find out whether you have a PCI motherboard. PCI is the name of a
338 bus system, i.e. the way the CPU talks to the other stuff inside
339 your box. Other bus systems are ISA, EISA, MicroChannel (MCA) or
340 VESA. If you have PCI, say Y, otherwise N.

349 ---help---
350 On PCI systems, the BIOS can be used to detect the PCI devices and
351 determine their configuration. However, some old PCI motherboards
352 have BIOS bugs and may crash if this is done. Also, some embedded
353 PCI-based systems don't have any BIOS at all. Linux can also try to
354 detect the PCI hardware directly without using the BIOS.
355
356 With this option, you can specify how Linux should detect the PCI
357 devices. If you choose "BIOS", the BIOS will be used, if you choose
358 "Direct", the BIOS won't be used, and if you choose "Any", the
359 kernel will try the direct access method and falls back to the BIOS
360 if that doesn't work. If unsure, go with the default, which is
361 "Any".
