<pre>I think it depends a bit on the specific model, but many Macs will only boot
EFI from USB. Refind (<a href="http://www.rodsbooks.com/refind/index.html">http://www.rodsbooks.com/refind/index.html</a>) is
potentially a way around that, although I'm not entirely sure if that counts as
booting in EFI mode or in BIOS mode.</pre>
