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.

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

371 have BIOS bugs and may crash if this is done. Also, some embedded
372 PCI-based systems don't have any BIOS at all. Linux can also try to
373 detect the PCI hardware directly without using the BIOS.
374
375 With this option, you can specify how Linux should detect the PCI
376 devices. If you choose "BIOS", the BIOS will be used, if you choose
377 "Direct", the BIOS won't be used, and if you choose "Any", the
378 kernel will try the direct access method and falls back to the BIOS
379 if that doesn't work. If unsure, go with the default, which is
