Are you sure it wasent doing a bios failback ? I'd be surprised to see a device like that with exclusive uEFI support ( although, I know lots of people run CentOS 6 on MacBook Air's and Macbook's of various shapes / sizes, which have no bios mode )
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")
to some extent yes, but once the machine is running and dmi stuff has been setup, there would be little impact
- 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"?)
its the same grub, running with different paths. There should be no stability impact as far as I can tell.
Thanks in advance for your advice or for providing more details about what you know about EFI pro and cons!
I've switched over everything that is capable of running uEFI to uEFI modes ( including my HP EliteBook laptop ) - and dont have any stability or performance issues ( that I've noticed anyway ).
