I have done install on several boards with UEFI; ASUS, Gigibyte, MSI,
ASrock, and All will boot stand-alone Linux installations Without issue
using either lilo or grub-0.xx series.

This cauldron system on an ASUS Crosshair V no issues using lilo
(have at times used grub).

A second system, Mandriva 10.1 on MSI 990FXA no issues using lilo.
