+.Sh NAME
+.Nm empb
+.Nd ELBOX Mediator 1200 PCI bridge driver
+.Sh SYNOPSIS
+.Cd "empb0 at zbus0"
+.Cd "emmem0 at zbus0"
+.Cd "pci* at empb0"
+.Cd "options PCI_NETBSD_CONFIGURE"
+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for the PCI bus present on Mediator 1200 bridge for
+Amiga 1200.
+.Sh HARDWARE
+The
+.Nm
+driver supports the following hardware:
+.Bl -tag -offset indent
+.It ELBOX Mediator 1200
+.It ELBOX Mediator 1200 LT2
+.It ELBOX Mediator 1200 LT4
+.It ELBOX Mediator 1200 SX
+.It ELBOX Mediator 1200 TX
+.El
+.Sh SEE ALSO
+.Xr mppb 4 ,
+.Xr p5pb 4 ,
+.Xr pci 4
+.Sh HISTORY
+The
+.Nm
+device first appeared in
+.Nx 7.0 .
+.Sh AUTHORS
+.An -nosplit
+The
+.Nm
+driver was written by
+.An Radoslaw Kujawa Aq radoslaw.kuj...@gmail.com .
+It was developed using information obtained through reverse engineering
+by Frank Wille and Radoslaw Kujawa. The authors have no access to official
+documentation (which is only available under NDA).
+.Sh CAVEATS
+Mediator 4000 and ZIV models are not supported, but support could easily be
+added if the developers had access to this hardware.
+.Sh BUGS
+DMA to host memory is not supported.
+This is a hardware limitation.
+It is possible to implement DMA through bounce buffers in graphics card memory,
+but this needs further research.
+.Pp
+PCI memory space access is buggy, this is a driver problem.
