.Sh NAME
.Nm pnpinfo
.Nd "Reports information about Plug-n-Play ISA devices"
.Sh SYNOPSIS
.Nm pnpinfo
.Sh DESCRIPTION
.Nm pnpinfo
reports information about Plug-n-Play ISA devices. Some of the information,
such as the vendor ID, serial number, I/O ports, IRQ, etc. are useful when
configuring a kernel with ISA PnP devices.
.Sh BUGS
A few of the tags are unimplemented (Enough exist for 99% of PnP cards).
.Sh SEE ALSO
.Xr pnp 4
.Sh HISTORY
The
.Nm
utility first appeared in
.Tn FreeBSD
2.2.
