+.SH NAME
+apm \- Alliance ProMotion video driver
+.SH SYNOPSIS
+.nf
+.B "Section \*qDevice\*q"
+.BI " Identifier \*q" devname \*q
+.B " Driver \*qapm\*q"
+\ \ ...
+.B EndSection
+.fi
+.SH DESCRIPTION
+.B 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.
+.SH SUPPORTED HARDWARE
+The
+.B apm
+driver supports PCI and ISA video cards on the following Alliance
+ProMotion chipsets
+.TP 12
+.B ProMotion 6420
+.TP 12
+.B ProMotion 6422
+.TP 12
+.B AT24
+.TP 12
+.B AT3D
+.TP 12
+.B AT25
+.SH CONFIGURATION DETAILS
+Please refer to XF86Config(__filemansuffix__) for general configuration
+details. This section only covers configuration details specific to this
+driver.
+.PP
+The driver auto-detects the chipset type, but the following
+.B ChipSet
+names may optionally be specified in the config file
+.B \*qDevice\*q
+section, and will override the auto-detection:
+.PP
+.RS 4
+"6422", "at24", "at3d".
+.PP
+The AT25 is Chipset "at3d" and the 6420 is 6422.
+.PP
+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
+.B VideoRam
+entry in the config file
+.B \*qDevice\*q
+section.
+.PP
+The following driver
+.B Options
+are supported:
+.TP
+.BI "Option \*qHWCursor\*q \*q" boolean \*q
+Enable or disable the hardware cursor. Default: on.
+.TP
+.BI "Option \*qNoAccel\*q \*q" boolean \*q
+Disable or enable acceleration. Default: acceleration is enabled.
+.TP
+.BI "Option \*qNoLinear\*q \*q" boolean \*q
+Disable or enable use of linear frame buffer. Default: on.
+Note: it may or may not work. Tell me if you need it.
+.TP
+.BI "Option \*qPciRetry\*q \*q" boolean \*q
+Enable or disable PCI retries. Default: off.
+.TP
+.BI "Option \*qRemap_DPMS_On\*q \*q" string \*q
+.TP
+.BI "Option \*qRemap_DPMS_Standby\*q \*q" string \*q
+.TP
+.BI "Option \*qRemap_DPMS_Suspend\*q \*q" string \*q
+.TP
+.BI "Option \*qRemap_DPMS_Off\*q \*q" string \*q
+Remaps the corresponding DPMS events. I've found that my
+Hercules 128/3D swaps Off and Suspend events. You can correct
+that with
+.nf
+.RS
+.RS
+.BI "Option \*qRemap_DPMS_Suspend\*q \*qOff\*q"
+.BI "Option \*qRemap_DPMS_Off\*q \*qSuspend\*q"
+.RE
+.fi
+in the
+.B Device
+section of the config file.
+.TP
+.BI "Option \*qSWCursor\*q \*q" boolean \*q
+Force the software cursor. Default: off.
+.TP
+.BI "Option \*qShadowFB\*q \*q" boolean \*q
+Enable or disable use of the shadow framebuffer layer. Default: off.
