46 | The Mappi-I is an FPGA board for SOC (System-On-a-Chip) prototyping. | |
47 | You can operate a Linux system on this board by using an M32R | |
48 | softmacro core, which is a fully-synthesizable functional model | |
49 | described in Verilog-HDL. | |
50 | ||
51 | The Mappi-I board was the first platform, which had been used | |
52 | to port and develop a Linux system for the M32R processor. | |
53 | Currently, the Mappi-II, an heir to the Mappi-I, is available. | |

271 | will run faster if you say N here. | |

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