A framebuffer is known to display graphics on a console that otherwise only shows text. You want to know how to write directly into the buffer. The framebuffers also are known to support video technology where it otherwise could not exist. Follow the steps below to figure out how, and feel free to have some fun in this tech-savvy process.
Step 1: Find the kernel source directory. This can be found usually by cd/usr/src/linux, and run your makemenuconfig program. Entries are located under device drivers and graphics support.
Step 2: Find Enable firmware EDID. If that kernel takes a while to load, disable it.
Step 3: Use MTRR option defaults 0-4. 0 means disabled; 1 means uncacheable; 2 means write-back; 3 means write-combining and 4 means write-through.
Step 4: A complete kernel command line would be /boot/grub/grub.conf.
