r128 - ATI Rage 128 video driver
r128 is an XFree86 driver for ATI Rage 128 based video cards.
It contains full support for 8, 15, 16 and 24 bit pixel depths, hardware
acceleration of drawing primitives, hardware cursor, video modes up to
1800x1440 @ 70Hz, doublescan modes (e.g., 320x200 and 320x240), gamma correction
at all pixel depths, a fully programming dot clock and robust text mode
restoration for VT switching.
The r128 driver supports
all ATI Rage 128 based video cards including the Rage Fury AGP 32MB, the
XPERT 128 AGP 16MB and the XPERT 99 AGP 8MB.
refer to XF86Config(5)
for general configuration details. This section
only covers configuration details specific to this driver.
The driver auto-detects
all device information necessary to initialize the card. 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 MMIO registers
ChipID - PCI DEVICE ID
In addition, the following driver Options are supported:
- Option "SWcursor" "boolean"
- Selects software cursor. The default is off.
- Option "NoAccel" "boolean"
- Enables or disables all hardware acceleration.
The default is to enable hardware acceleration.
- Option "Dac6Bit" "boolean"
- Enables or disables the use of 6 bits per color component when in 8 bpp
mode (emulates VGA mode). By default, all 8 bits per color component are
used. The default is off.
- Option "VideoKey" "integer"
- This overrides the
default pixel value for the YUV video overlay key. The default value is
