Default video modes¶
At the moment, there are two kernel command line arguments supported:
- mode:640x480 
- mode:800x600 
- mode:1024x768 
Full support for startup video modes (modedb) will be integrated soon.
Version 1.9.9.1¶
- Fix memory detection for 512kB case 
- 800x600 mode 
- Fixed timings 
- Hint for AXP: Use -accel false -vyres -1 when changing resolution 
Version 1.9.4.4¶
- Preliminary Laguna support 
- Overhaul color register routines. 
- Associated with the above, console colors are now obtained from a LUT called ‘palette’ instead of from the VGA registers. This code was modelled after that in atyfb and matroxfb. 
- Code cleanup, add comments. 
- Overhaul SR07 handling. 
- Bug fixes. 
Version 1.9.4.3¶
- Correctly set default startup video mode. 
- Do not override ram size setting. Define CLGEN_USE_HARDCODED_RAM_SETTINGS if you _do_ want to override the RAM setting. 
- Compile fixes related to new 2.3.x IORESOURCE_IO[PORT] symbol changes. 
- Use new 2.3.x resource allocation. 
- Some code cleanup. 
Version 1.9.4.2¶
- Casting fixes. 
- Assertions no longer cause an oops on purpose. 
- Bug fixes. 
Version 1.9.4.1¶
- Add compatibility support. Now requires a 2.1.x, 2.2.x or 2.3.x kernel. 
Version 1.9.4¶
- Several enhancements, smaller memory footprint, a few bugfixes. 
- Requires kernel 2.3.14-pre1 or later. 
Version 1.9.3¶
- Bundled with kernel 2.3.14-pre1 or later.
