| |
For use mainly by graphical installation disks, I have written a `least common denominator' 640x480x16 framebuffer for VGA and compatible cards. It is essentially complete. You can find it at http://pfaffben.user.msu.edu/~blp and http://www.msu.edu/user/pfaffben
To use it, patch a 2.2.0 kernel pre-patch with vga16.patch, then select `VGA 16-color graphics console' and `VGA 16-color planar support' in configuration. When you reboot, you must specify vga=274 (which is 0x112 in hex) to kick your card into the proper video mode for use by VGA16 (I have not implemented mode-setting yet).
Question: does anyone know why the entire screen turns white before the kernel messages start scrolling up? I hunted through the kernel source code for this, but couldn't quite figure it out.
Additional comments and suggestions are welcome.
Thanks,
Ben. -- "To the engineer, the world is a toy box full of sub-optimized and feature-poor toys." --Scott Adams
