.Sh HISTORY
The

device first appeared in
.Nx 6.0 .
.Sh AUTHORS
.An -nosplit
The
.Nm
driver was written by
.An Radoslaw Kujawa Aq radoslaw.kujawa@gmail.com .
.Sh CAVEATS
G-REX PCI bridge is currently not supported, however the driver
will try to attach to it, because it has the same vendor and product
ID as CVPPC/BVPPC cards.
Due to similarities between these products, it may even detect the
card inserted into first slot, but the driver will (most likely)
not work properly.
.Pp
Support for CV64/3D is disabled by default, since the
.Xr grfcv3d 4
driver does attach directly to
.Xr zbus 4 .
Machine independent PCI driver for S3 ViRGE does not exist yet.
.Sh BUGS
Current version of this driver depends on PCI bus setup and enumeration
done by the firmware.
.Pp
The driver will not attach at all, if there is no AutoConfig entry
for CVPPC/BVPPC card (Zorro product ID 110).
Some firmware revisions are known not to create this entry.
.Pp
It is not (yet) possible to use the CVPPC/BVPPC as a console.
