NAME
       apm - Alliance ProMotion	video driver

SYNOPSIS
       Section "Device"
	 Identifier "devname"
	 Driver	"apm"
	 ...
       EndSection

DESCRIPTION
       apm is an XFree86 driver	for Alliance ProMotion video cards. The	driver
       is accelerated for supported hardware/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 following ChipSet
       names may optionally be specified in the	config 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 memory	can also be specified  with  a
       VideoRam	entry in the config file "Device" section.

       The following driver Options are	supported:

       Option "HWCursor" "boolean"
	      Enable or	disable	the hardware cursor.  Default: on.

       Option "SWCursor" "boolean"
	      Force the	software cursor.  Default: off.

       Option "NoAccel"	"boolean"
	      Disable	or  enable  acceleration.   Default:  acceleration  is
	      enabled.

       Option "NoLinear" "boolean"
	      Disable or enable	use  of	 linear	 frame	buffer.	 Default:  on.
	      Note: it may or may not work. Tell me if you need	it.

       Option "PciRetry" "boolean"
	      Enable or	disable	PCI retries.  Default: off.

       Option "Remap_DPMS_On" "string"

       Option "Remap_DPMS_Standby" "string"

       Option "Remap_DPMS_Suspend" "string"

       Option "Remap_DPMS_Off" "string"
	      Remaps  the  corresponding  DPMS events. I've found that my Her-
	      cules 128/3D swaps Off and Suspend events. You can correct  that
	      with
		     Option "Remap_DPMS_Suspend" "Off"
		     Option "Remap_DPMS_Off" "Suspend"
	      in the Device section of the config file.

       Option "ShadowFB" "boolean"
	      Enable or	disable	use of the shadow framebuffer layer.  Default:
	      off.
