1802 Loongson 2F03 and later have fixed these issues and no workarounds
1803 are needed. The workarounds have no significant side effect on them
1804 but may decrease the performance of the system so this option should

3052 The EISA bus provided some of the features of the IBM MicroChannel
3053 bus while maintaining backward compatibility with cards made for
3054 the older ISA bus. The EISA bus saw limited use between 1988 and
3055 1995 when it was made obsolete by the PCI bus.
