<li>Matthew J. Garrett, the developer of the shim boot loader to manage Secure Boot, maintains <a href="http://mjg59.dreamwidth.org/">a blog</a> in which he often writes about EFI issues.</li>

<li>J. A. Watson has a <a href="http://www.zdnet.com/the-refind-boot-loader-for-uefi-systems-7000010275/">review of rEFInd on an HP laptop</a> on ZDNet. He had serious problems because of the HP's UEFI bugs, but finally got it to work.</li>
<li>James Jesudason has a tutorial on installing Ubuntu 13.04 beta on a Macbook Retina Pro on <a href="http://randomtutor.blogspot.com/2013_02_01_archive.html">this blog page.</a> I'd recommend using a Linux filesystem driver to read the kernel directly from a Linux filesystem rather than copy the kernel to the OS X partition as in the tutorial, but either method will work.</li>
