  33Default video modes
  34-------------------
  35At the moment, there are two kernel command line arguments supported:
  36
  37mode:640x480
  38mode:800x600
  39        or
  40mode:1024x768
  41
  42Full support for startup video modes (modedb) will be integrated soon.

  44Version 1.9.9.1
  45---------------
  46* Fix memory detection for 512kB case
  47* 800x600 mode
  48* Fixed timings
  49* Hint for AXP: Use -accel false -vyres -1 when changing resolution
  50
  51
  52Version 1.9.4.4
  53---------------
  54* Preliminary Laguna support
  55* Overhaul color register routines.
  56* Associated with the above, console colors are now obtained from a LUT
  57  called 'palette' instead of from the VGA registers.  This code was
  58  modeled after that in atyfb and matroxfb.
  59* Code cleanup, add comments.
  60* Overhaul SR07 handling.
  61* Bug fixes.
  62
  63
  64Version 1.9.4.3
  65---------------
  66* Correctly set default startup video mode.
  67* Do not override ram size setting.  Define
  68  CLGEN_USE_HARDCODED_RAM_SETTINGS if you _do_ want to override the RAM
  69  setting.
  70* Compile fixes related to new 2.3.x IORESOURCE_IO[PORT] symbol changes.
  71* Use new 2.3.x resource allocation.
  72* Some code cleanup.
  73
  74
  75Version 1.9.4.2
  76---------------
  77* Casting fixes.
  78* Assertions no longer cause an oops on purpose.
  79* Bug fixes.
  80
  81
  82Version 1.9.4.1

  84* Add compatibility support.  Now requires a 2.1.x, 2.2.x or 2.3.x kernel.
  85
  86
  87Version 1.9.4
  88-------------
  89* Several enhancements, smaller memory footprint, a few bugfixes.
  90* Requires kernel 2.3.14-pre1 or later.
  91
  92
