# Getting U-Boot
Jetson TK1 boards come with Linux4Tegra R19.x installed, which doesn't use U-Boot. The easiest way to get U-Boot is to upgrade to Linux4Tegra R21.x (Linux PC or VM required) following the [quick start guide](http://developer.download.nvidia.com/embedded/L4T/r21_Release_v4.0/l4t_quick_start_guide.txt).
# Modesetting
To be able to use the mode setting features of the Tegra DRM driver, you must use the xf86-video-modesetting driver. Put this in xorg.conf:
[[!template id=programlisting text="""
Section "Device"
Identifier "DRM Modesetting"
Driver "modesetting"
EndSection
