The EISA bus saw limited use between 1988 and 806 1995 when it was made obsolete by the PCI bus. 807 808 Say Y here if you are building a kernel for an EISA-based machine. 809 810 Otherwise, say N. 811 812config MCA 813 bool 814 help 815 MicroChannel Architecture is found in some IBM PS/2 machines and 816 laptops.
