39 .Nd introduction to ISA bus support
43 The system includes a machine-independent
45 bus subsystem and several machine-independent
49 Note that interrupt mappings on the i386 may require that you configure
50 your BIOS to reserve the interrupts for these devices as "Legacy ISA".
51 If such configuration is not done, the system may use those interrupts
