853 | help | |
854 | The Maple Bus is SEGA's serial communication bus for peripherals | |
855 | on the Dreamcast. Without this bus support you won't be able to | |
856 | get your Dreamcast keyboard etc to work, so most users | |
857 | probably want to say 'Y' here, unless you are only using the | |
858 | Dreamcast with a serial line terminal or a remote network | |
859 | connection. | |

867 | help |
868 | Find out whether you have a PCI motherboard. PCI is the name of a | |
869 | bus system, i.e. the way the CPU talks to the other stuff inside | |
870 | your box. If you have PCI, say Y, otherwise N. | |
