3. Technical Notes

None

4. Reported Working Video Cards

Rage Fury AGP 32MB
XPERT 128 AGP 16MB
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 xorg.conf file are:

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

or let xorgconfig do this for you.

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

VideoRam - in kilobytes
MemBase - physical address of the linear framebuffer
IOBase - physical address of the memory mapped IO registers
ChipID - PCI DEVICE ID

6. Driver Options

"hw_cursor" - request hardware cursor (default)
"sw_cursor" - software cursor only
"no_accel" - software rendering only
"dac_8_bit" - use color weight 888 in 8 bpp mode (default)
"dac_6_bit" - use color weight 666 in 8 bpp mode (VGA emulation)

7. Known Limitations

None
