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.

287 you say Y here, the kernel will run on many, but not all,

289 will run faster if you say N here.

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