1.  Supported Hardware

   o ATI Rage 128 based cards

2.  Features

   o Full support (including hardware accelerated 2D drawing) for 8, 15, 16,
     24 bit pixel depths.

   o Hardware cursor support to reduce sprite flicker.

   o Support for high resolution video modes up to 1800x1440 @ 70Hz.

   o Support for doublescan video modes (e.g., 320x200 and 320x240).

   o Support for gamma correction at all pixel depths.

   o Fully programmable clock supported.

   o Robust text mode restore for VT switching.

3.  Technical Notes

   o None

4.  Reported Working Video Cards

   o Rage Fury AGP 32MB

   o XPERT 128 AGP 16MB

   o XPERT 99 AGP 8MB

5.  Configuration

The driver auto-detects all device information necessary to initialize the
card.  The only lines you need in the "Device" section of your XF86Config
file are:

            Section "Device"
                Identifier "Rage 128"
                Driver     "r128"
            EndSection

or let xf86config do this for you.

However, if you have problems with auto-detection, you can specify:

   o VideoRam - in kilobytes

   o MemBase  - physical address of the linear framebuffer

   o IOBase   - physical address of the memory mapped IO registers

   o ChipID   - PCI DEVICE ID

6.  Driver Options

   o "hw_cursor" - request hardware cursor (default)

   o "sw_cursor" - software cursor only

   o "no_accel"  - software rendering only

   o "dac_8_bit" - use color weight 888 in 8 bpp mode (default)

   o "dac_6_bit" - use color weight 666 in 8 bpp mode (VGA emulation)

7.  Known Limitations

   o None
