DESCRIPTION

       apm  is	an  XFree86  driver  for Alliance ProMotion video
       cards. The  driver  is  accelerated  for	 supported  hard
       ware/depth  combination. It supports framebuffer depths of
       8, 15, 16, 24 and 32 bits. For 6420, 6422, AT24, AT3D  and
       AT25,  all  depths are fully accelerated except 24 bpp for
       which only screen to screen copy and rectangle filling  is
       accelerated.


SUPPORTED HARDWARE

       The  apm	 driver	 supports  PCI and ISA video cards on the
       following Alliance ProMotion chipsets

       ProMotion 6420

       ProMotion 6422

       AT24

       AT3D

       AT25


CONFIGURATION DETAILS

       Please refer to XF86Config(5)  for  general  configuration
       details.	  This	section only covers configuration details
       specific to this driver.

       The driver auto-detects the chipset type, but the  follow
       ing  ChipSet names may optionally be specified in the con
       fig file "Device" section, and  will  override  the  auto-
       detection:

	   "6422", "at24", "at3d".

	   The AT25 is Chipset "at3d" and the 6420 is 6422.

	   The driver will auto-detect the amount of video memory
	   present for all chips. The actual amount of video mem
	   ory can also be specified with a VideoRam entry in the
	   config file "Device" section.

	   The following driver Options are supported:
