The PGX framebuffer card is an 8-bit, PCI-based, 2-D acceleration graphics
card that supports the following following resolutions:

   - 1600 x 1000, 76 Hz refresh rate, single buffered
		  66 Hz
   - 1440 x  900, 76 Hz refresh rate, single buffered
   - 1280 x  800, 76 Hz refresh rate, single buffered
		  75 Hz
		  67 Hz
		  60 Hz
   - 1152 x  900, 76 Hz refresh rate
		  66 Hz
   - 1024 x  768, 75 Hz refresh rate
		  70 Hz
		  60 Hz
   -  800 x  600, 75 Hz refresh rate
   -  768 x  575, 50 Hz refresh rate
   -  640 x  480, 60 Hz refresh rate

In order to change the resolution, you need to issue the m64config command.
For most installations, the M64 Frame Buffer card will automatically configure 
itself to the proper screen resolution and refresh rate for your monitor. 
However, if a non-Sun monitor is connected to the M64 Frame Buffer, the monitor 
may come up in the wrong screen resolution. 

To see which resolutions are supported on your system for the card, issue the
command
	/usr/sbin/m64config -res \?

If the command cannot be found on the system, make sure that SUNWm64cf is 
installed.

When installed, the PGX framebuffer will show up as /dev/m640.

The card is not supported on the Ultra1[TM] and Ultra2[TM] or any other SuperSPARC[TM]
based systems.  It'll work on any PCI equipped Sun system and is standard
on the Ultra 5 and Ultra 10 motherboards.
