Hello, I am using an up to date CentOS 6 x86_64 laptop (Thinkpad X220t) and after struggling a bit I could install it a few months ago with a pure EFI boot. However, I am not really satisfied with such things as stability, power consumption, etc. and now that I have a little more time I want to investigate these issues thoroughly. So, my questions are: - Does EFI impacts other things than the boot sequence? (a friend of mine told me that this is a complete replacement of BIOS, and thus impacts "everything") - Could it change (improve?) stability, power consumption, etc. if I would reinstall CentOS 6 using the traditional boot? (or is it just a legacy wrapper around an EFI "BIOS"?) Thanks in advance for your advice or for providing more details about what you know about EFI pro and cons! Cheers, Mathieu
