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---------------

77* Assertions no longer cause an oops on purpose.
78* Bug fixes.
