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 sup-
       ports 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 Hercules 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.
