Configuration with a dynamic server

The SCO X Server uses a dynamic loading mechanism to access different drivers. A new display driver is installed into the apropriate directory, in a manner similar to how a device driver exists in the kernel link kit. Each driver resides in a directory named after itself. The object modules have a specified name and pathname, shown in the following table:

Platform	Object name	Example: full pathname of nte8 driver
SCO OpenServer 5	XDriver.o	/usr/lib/X11/dyddx/nte8/XDriver.o
SVR5	libXDriver.o	/usr/X/lib/X11/dyddx/nte8/libXDriver.o

At startup, the server does the following:

• Looks at the /usr/lib/grafinfo/grafdev file to see which adapters are installed.

• Reads the appropriate grafinfo(DSP/4dsp) file.

• Searches dyddx tree for the appropriate driver directory, using the XDRIVER variable from the grafinfo file.

• When the matching directory is found, the server dynamically loads the module.

• This is repeated for each adapter which is loaded into the server.

As the X Server detects each graphics adapter that is configured by the user, it automatically pulls in the display driver needed for that piece of hardware.
