.Sh NAME
.Nm isa
.Nd introduction to ISA bus support
.Sh SYNOPSIS
.Cd "device isa"
.Sh DESCRIPTION
The system includes a machine-independent
.Tn ISA
bus subsystem and several machine-independent
.Tn ISA
device drivers.
.Pp
Note that interrupt mappings on the i386 may require that you configure
your BIOS to reserve the interrupts for these devices as "Legacy ISA".
If such configuration is not done, the system may use those interrupts
for
.Xr pci 4
devices instead.
