        ==================
	HP Product Numbers
	==================

	The following displays are supported with this CFB X Server.

	Please refer to the HP catalog or to the apropriate data sheets
	for the displays.  The following data relates the use of the 
	product names with their official HP product numbers:

	HPA1659A  CRX       1280x1024 Color, 8 planes
	
	HPA1439A  CRX24	    1280x1024 Color, 24 planes

	HPA1924A  GRX       1280x1024 Grayscale, 8 planes

	HPA2269A  Dual CRX  1280x1024 Color, 8 planes, two displays

	HP710C    710 SPU   1280x1024 Color, 8 planes

	HP710G    710 SPU   1280x1024 Grayscale, 8 planes

	HP710L    710 SPU   1024x768 Color, 8 planes

	
	=======================
	MULTIPLE SCREEN SUPPORT
	=======================

	The HP X11 sample server supports multiple physical screens
	connected to a single server program.  The file
	/usr/lib/X11/X*screens is read by the X11 server to determine
	information about the system screen configuration.

	For a complete description of the X*screens file, refer to the
	HP-UX manuals, or view the sample file in /usr/lib/X11.
	
	==========================
	24 PLANE SUPPORT FOR CRX24
	==========================
	
	The HP X11 sample server support two modes for the CRX24 display
	hardware:  8 plane and 24 plane, with 8 plane being the default.
	To run the server in 24 plane mode, add a depth parameter to
	the Xnscreens file.  For example:
	
		/dev/crt  depth 24
		
	In depth 24 mode, the default visual type is DirectColor.


	=====================
	FAST SCROLLING OPTION
	=====================

	Since scrolling speed is especially slow on this server compared
	to HP's product server, we have supplied fast scrolling support,
	using a .o to link into the server.  Using HP's fast scrolling
	is optional.  To enable the fast scrolling, set the token
	"HPFastScrolling" to TRUE in the config/hp.cf file.  If you want
	to use the CFB scrolling module, simply remove the define in
	config/hp.cf, remake the Makefiles, and recompile.
