0033 Default video modes
0034 -------------------
0035 At the moment, there are two kernel command line arguments supported:
0036
0037 - mode:640x480
0038 - mode:800x600
0039 - mode:1024x768
0040
0041 Full support for startup video modes (modedb) will be integrated soon.
0042
0043 Version 1.9.9.1
0044 ---------------
0045 * Fix memory detection for 512kB case
0046 * 800x600 mode
0047 * Fixed timings
0048 * Hint for AXP: Use -accel false -vyres -1 when changing resolution
0049
0050
0051 Version 1.9.4.4
0052 ---------------
0053 * Preliminary Laguna support
0054 * Overhaul color register routines.
0055 * Associated with the above, console colors are now obtained from a LUT
0056 called 'palette' instead of from the VGA registers. This code was
0057 modelled after that in atyfb and matroxfb.
0058 * Code cleanup, add comments.
0059 * Overhaul SR07 handling.
0060 * Bug fixes.
0061
0062
0063 Version 1.9.4.3
0064 ---------------
0065 * Correctly set default startup video mode.
0066 * Do not override ram size setting. Define
0067 CLGEN_USE_HARDCODED_RAM_SETTINGS if you _do_ want to override the RAM
0068 setting.
0069 * Compile fixes related to new 2.3.x IORESOURCE_IO[PORT] symbol changes.
0070 * Use new 2.3.x resource allocation.
0071 * Some code cleanup.
0072
0073
0074 Version 1.9.4.2
0075 ---------------
0076 * Casting fixes.
0077 * Assertions no longer cause an oops on purpose.
0078 * Bug fixes.
0079
0080

0084
0085
0086 Version 1.9.4
0087 -------------
0088 * Several enhancements, smaller memory footprint, a few bugfixes.
0089 * Requires kernel 2.3.14-pre1 or later.
0090
