Marie.o: initial notes on using Sandybridge based stuff

initial notes on using Sandybridge based stuff

New page

This page contains some notes regarding getting a Sandy Bridge based MD working.

After doing a 1004 MD setup, I've changed all Ubuntu Lucid URLs in sources.list to natty and apt-get dist-upgraded, until I no longer had anything missing. Make sure to change the softlink in /tftroot on the core to point to the newest vmlinuz and initrd in the diskless dir.

The main reason for going natty is the support for the graphics chipset out of the box in natty. BUT, starting the system resulted in not much success. Many times I'd see stuff like:
intel(0): [drm] failed to set drm interface version.

Playing a bit around the solution was to remove the xserver-xorg-video-vesa and xserver-xorg-video-fbdev - after that X and the Orbiter came up in all their glory.
