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

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

353 With this option, you can specify how Linux should detect the PCI
354 devices. If you choose "BIOS", the BIOS will be used, if you choose
355 "Direct", the BIOS won't be used, and if you choose "Any", the

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

312 This allows you to specify the maximum number of CPUs which this
313 kernel will support. The maximum supported value is 32 and the
314 minimum value which makes sense is 2.
315
316 This is purely to save memory - each supported CPU adds
317 approximately eight kilobytes to the kernel image.

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

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