1778 Loongson 2F03 and later have fixed these issues and no workarounds
1779 are needed. The workarounds have no significant side effect on them
1780 but may decrease the performance of the system so this option should
1781 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1782 systems.

2982 bus system, i.e. the way the CPU talks to the other stuff inside
2983 your box. Other bus systems are ISA, EISA, or VESA. If you have PCI,
2984 say Y, otherwise N.

3016 The Extended Industry Standard Architecture (EISA) bus was
3017 developed as an open alternative to the IBM MicroChannel bus.
3018
3019 The EISA bus provided some of the features of the IBM MicroChannel
3020 bus while maintaining backward compatibility with cards made for
3021 the older ISA bus. The EISA bus saw limited use between 1988 and
3022 1995 when it was made obsolete by the PCI bus.
3023
3024 Say Y here if you are building a kernel for an EISA-based machine.
