 .Sh DESCRIPTION
 The
 .Nm
-driver provides support for the PCI bus present on BlizzardVisionPPC,
-CyberVisionPPC and CybrerVision 64/3D graphics cards.
+driver provides support for the PCI bus present on various devices equipped with
+the Phase5 PCI bridge. 
+.Pp
+Processor boards running firmware revision older than 44.69 need a kernel 
+configured with P5PB_OLD_FIRMWARE option. 
+.Pp
+The
+.Nm 
+driver provides necessary support for CyberVisionPPC and BlizzardVisionPPC, 
+allowing attachment of 
+.Xr genfb 4
+driver. 
+Owners of these cards should enable the P5PB_GENFB option.
+.Pp
+Additional, excessive debugging output is enabled by P5PB_DEBUG option.
 .Sh HARDWARE

 driver was written by
 .An Radoslaw Kujawa Aq radoslaw.kujawa%gmail.com@localhost .
 .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.
+The
+.Nx developers don't have access to G-REX hardware or documentation.
+Support for this device is based on best wishes. 
 .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.
+Support for 
+.Xr genfb 4
+framebuffer on CVPPC/BVPPC needs more testing.
 .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.
+DMA to host memory is not supported. This is a driver limitation.
 .Pp
-It is not (yet) possible to use the CVPPC/BVPPC as a console.
+The P5PB_OLD_FIRMWARE option should only be enabled if PCI hardware is 
+present. Otherwise kernel panic might occur due to bus error.
