33 | Default video modes | ||
34 | ------------------- | ||
35 | At the moment, there are two kernel command line arguments supported: | ||
36 | |||
37 | mode:640x480 | ||
38 | mode:800x600 | ||
39 | or | ||
40 | mode:1024x768 | ||
41 | |||
42 | Full support for startup video modes (modedb) will be integrated soon. | ||
43 | |||
44 | Version 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 | |||
52 | Version 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 | |||
64 | Version 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 | |||
75 | Version 1.9.4.2 | ||
76 | --------------- | ||
77 | * Casting fixes. | ||
78 | * Assertions no longer cause an oops on purpose. | ||
79 | * Bug fixes. | ||
80 | |||
81 | |||
82 | Version 1.9.4.1 | ||
83 | --------------- | ||
84 | * Add compatibility support. Now requires a 2.1.x, 2.2.x or 2.3.x kernel. | ||
85 | |||
86 | |||
87 | Version 1.9.4 | ||
88 | ------------- | ||
89 | * Several enhancements, smaller memory footprint, a few bugfixes. | ||
90 | * Requires kernel 2.3.14-pre1 or later. | ||
91 | |||
92 | |||
93 | Version 1.9.3 | ||
94 | ------------- | ||
95 | * Bundled with kernel 2.3.14-pre1 or later. | ||
