.Sh NAME
.Nm eisa
.Nd Introduction to EISA bus machine-independent drivers and support
.Sh SYNOPSIS
.Cd options EISAVERBOSE
.Pp
Machine-dependent; depends on the bus topology and
.Tn EISA
bus interface of your system.  Typical
.Tn EISA
buses are either connected directly
to the main system bus, or via an
.Tn PCI
to
.Tn EISA
bridge.  See the
.Xr intro 4
documentation for your system for details.
.Sh DESCRIPTION
.Nx
includes a machine-independent
.Tn EISA
bus subsystem and several machine-independent
.Tn EISA
device drivers.
.Pp
Your system may support additional
.Tn EISA
devices.
Drivers for
.Tn EISA
devices not listed here are machine-dependent.
Consult your system's
.Xr intro 4
for additional information.
.Sh SUPPORTED DEVICES
.Nx
includes machine-independent
.Tn EISA
drivers, sorted by device type
and driver name:

.Pp
Note that most or all
.Tn EISA
devices also have
.Tn PCI
or
.Tn ISA
equivalents.
These are listed in
.Xr pci 4 ,
.Xr isa 4 ,
or
.Xr isapnp 4 ,
respectively.  The manual pages for each individual driver also lists the
supported bus variants.
