1081 might be a safe bet. If the resulting kernel does not work,

1906 Find out whether you have a PCI motherboard. PCI is the name of a
1907 bus system, i.e. the way the CPU talks to the other stuff inside
1908 your box. Other bus systems are ISA, EISA, or VESA. If you have PCI,
1909 say Y, otherwise N.

1935 The Extended Industry Standard Architecture (EISA) bus was
1936 developed as an open alternative to the IBM MicroChannel bus.
1937
1938 The EISA bus provided some of the features of the IBM MicroChannel
1939 bus while maintaining backward compatibility with cards made for
1940 the older ISA bus. The EISA bus saw limited use between 1988 and
1941 1995 when it was made obsolete by the PCI bus.
1942
1943 Say Y here if you are building a kernel for an EISA-based machine.
