The patch additionally...

From: Matt Fleming <matt.fleming at linux.intel.com> This series fixes some bugs and switches the elflink branch to be entirely ELF modules. It applies on top of, http://syslinux.zytor.com/archives/2011-April/016369.html The deletions in the diff stat below are mainly from deleting com32/elflink/modules (finally!). Now there should be no duplicate code because we don't need COM32 and

Hello all, We're having the following issue: when in UEFI mode, any output/errors from a lua script is invisible! This occurs even just running 'lua -v'. It runs and returns to a (visible) 'boot:' prompt, but there is simply no output visible from lua! (It does do a linefeed, but no visible text appears.) Has anyone encountered this? And/or know of a solution? For
