  33Default video modes
  34-------------------
  35At the moment, there are two kernel command line arguments supported:
  36
  37- mode:640x480
  38- mode:800x600
  39- mode:1024x768

  41Full support for startup video modes (modedb) will be integrated soon.

  43Version 1.9.9.1
  44---------------
  45* Fix memory detection for 512kB case
  46* 800x600 mode
  47* Fixed timings
  48* Hint for AXP: Use -accel false -vyres -1 when changing resolution

  51Version 1.9.4.4
  52---------------
  53* Preliminary Laguna support
  54* Overhaul color register routines.
  55* Associated with the above, console colors are now obtained from a LUT
  56  called 'palette' instead of from the VGA registers.  This code was
  57  modelled after that in atyfb and matroxfb.
  58* Code cleanup, add comments.
  59* Overhaul SR07 handling.
  60* Bug fixes.
  61
  62
  63Version 1.9.4.3
  64---------------
  65* Correctly set default startup video mode.
  66* Do not override ram size setting.  Define
  67  CLGEN_USE_HARDCODED_RAM_SETTINGS if you _do_ want to override the RAM
  68  setting.
  69* Compile fixes related to new 2.3.x IORESOURCE_IO[PORT] symbol changes.
  70* Use new 2.3.x resource allocation.
  71* Some code cleanup.
  72
  73
  74Version 1.9.4.2
  75---------------

  84
  85
  86Version 1.9.4
  87-------------
  88* Several enhancements, smaller memory footprint, a few bugfixes.
  89* Requires kernel 2.3.14-pre1 or later.
