56 The Mappi-I is an FPGA board for SOC (System-On-a-Chip) prototyping.
57 You can operate a Linux system on this board by using an M32R
58 softmacro core, which is a fully-synthesizable functional model
59 described in Verilog-HDL.
60
61 The Mappi-I board was the first platform, which had been used
62 to port and develop a Linux system for the M32R processor.
63 Currently, the Mappi-II, an heir to the Mappi-I, is available.

282 than one CPU, say Y.
283
284 If you say N here, the kernel will run on uni- and multiprocessor
285 machines, but will use only one CPU of a multiprocessor machine. If
286 you say Y here, the kernel will run on many, but not all,
287 uniprocessor machines. On a uniprocessor machine, the kernel
288 will run faster if you say N here.

291 Y to "Enhanced Real Time Clock Support", below. The "Advanced Power

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