34-------------------
35At the moment, there are two kernel command line arguments supported:

37mode:640x480
38mode:800x600
39 or
40mode:1024x768

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.

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
93Version 1.9.3
94-------------
95* Bundled with kernel 2.3.14-pre1 or later.
