.Nd introduction to ISA bus support
.Sh SYNOPSIS
.Cd "# amd64 and i386"
.Cd "isa0 at mainbus0"
.Cd "isa0 at pcib?"

.Cd "# i386"
.Cd "isa0 at ichpcib?"

.Pp
Attachments are machine-dependent and depend on the bus topology and
.Tn ISA
bus interface of your system.
See
.Xr intro 4
for your system for details.
.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
or
.Xr isapnp 4
devices instead.
.Pp
