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

345 VESA. If you have PCI, say Y, otherwise N.
348 prompt "PCI access mode"
355 On PCI systems, the BIOS can be used to detect the PCI devices and
356 determine their configuration. However, some old PCI motherboards
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.
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
