+ ______________________________________________________________________
+
+ 1. Introduction
+
+ This document provides a brief summary of the i810/i815 support
+ provided by the i810 driver. Support for later chipsets is not
+ covered here. More up to date information about the i810 driver can
+ be found in the i810(4) manual page.
+
+
+ 2. Supported Hardware
+
+
+ +o Intel 810 motherboards:
+
+ +o i810,
+
+ +o i810-dc100,
+
+ +o i810e
+
+ +o i815
+
+
+
+ 3. 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.
+
+
+
+ 4. 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 recent versions
+ of FreeBSD. It requires the agpgart kernel support, which is
+ included in Linux kernels 2.3.42 and higher, and FreeBSD 4.1 and
+ higher.
+
+
+
+ 5. Reported Working Video Cards
+
+
+ +o Intel evaluation hardware - i810, i810-dc100, i810e and i815.
+
+ +o Tyan Tomcat Motherboard.
+
+ +o HappyPC set-top box.
+
+
+
+ 6. 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 "Intel i810"
+ Driver "i810"
+ EndSection
+
+
+ or let xorgconfig 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 (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.
+
+
+
+ 7. 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)
+
+
+ 8. Known Limitations
+
+
+ +o No 3D support in this release.
+
+ +o Running two X servers on different VTs is not supported at this
+ time.
