DESCRIPTION

The cgtwo interface provides access to the cg30 color graphics controller board.  It provides the standard frame buffer interface as defined in fbio(4S) with one additional ioctl.  The FBIOSOLBOURNE ioctl will return the Solbourne-specific frame buffer type (defined in <mfg/fbio.h>).  This ioctl is designed to return -1 on Sun systems so applications can determine if Solbourne graphics extensions are present.
