-
- 1. Supported Hardware
-
- o Intel 810 motherboards:
-
- o i810,
-
- o i810-dc100,
-
- o i810e
-
- 2. Features
-
- o Full support for 8, 15, 16, and 24 bit pixel depths.
-
- o Hardware cursor support to reduce sprite flicker.
-
- o Hardware accelerated 2D drawing engine support for 8, 15, 16 and 24 bit
- pixel depths.
-
- o Support for high resolution video modes up to 1600x1200.
-
- o Fully programmable clock supported.
-
- o Robust text mode restore for VT switching.
-
- 3. Technical Notes
-
- o Hardware acceleration is not possible when using the framebuffer in 32
- bit per pixel format, and this mode is not supported by this driver.
-
- o Interlace modes cannot be supported.
-
- o This driver currently only works for Linux/ix86, and normal use requires
- the agpgart.o kernel module, included in Linux kernels 2.3.42 and
- higher.
-
- 4. Reported Working Video Cards
-
- o Intel evaluation hardware - i810, i810-dc100 and i810e.
-
- o Tyan Tomcat Motherboard.
-
- o HappyPC set-top box.
-
- 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 "Intel i810"
- Driver "i810"
- EndSection
-
- or let xf86config do this for you.
-
- However, if you have problems with auto-detection, you can specify:
-
- o DacSpeed - in MHz
-
- o MemBase - physical address of the linear framebuffer
-
- o IOBase - physical address of the memory mapped IO registers
-
- In order to use most resolutions, it is necessary to install the 'agpgart.o'
- module. You will probably have to compile the module yourself (see the notes
- in the module).
-
- Note: the i810 driver detects whether your motherboard has display cache
- video memory. This memory is has reduced bandwidth compared to normal system
- memory, and isn't used by the server. The main function of this memory is
- for ancillary buffers (eg. z buffer) in a forthcoming 3d capable server.
-
- 6. Driver Options
-
- o "NoAccel" - Turn off hardware acceleration
-
- o "SWCursor" - Request a software cursor (hardware is default)
-
- o "Dac6Bit" - Force the use of a 6 Bit Dac (8 Bit is the default)
-
- 7. Known Limitations
-
- o No 3D support in this release.
-
- o Running two X servers on different VTs is not supported at this time.
