41 | Full support for startup video modes (modedb) will be integrated soon. | |
42 | ||
43 | Version 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 | |

50 | ||
51 | Version 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 | |
f884ab15 | 57 | modelled after that in atyfb and matroxfb. |

60 | * Bug fixes. | |
61 | ||
62 | ||
63 | Version 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 | ||
74 | Version 1.9.4.2 | |

84 | ||
85 | ||
86 | Version 1.9.4 | |
87 | ------------- | |
88 | * Several enhancements, smaller memory footprint, a few bugfixes. | |
89 | * Requires kernel 2.3.14-pre1 or later. | |
