UEFI & Linux

From: John Aldrich 
Anyone installed Linux on a UEFI BIOS system yet? Can you upgrade an existing 
system that doesn't have UEFI BIOS to a new motherboard that does? Thinking 
about upgrading my current dual-core system to something more powerful (like I 
*need* more power, but... :D) but I think pretty much everything is going UEFI 
and I really don't want to have to reinstall from scratch just to get UEFI to 
allow my system to boot!

=============================================================== From: Matt Keys ------------------------------------------------------ I've installed ubuntu and centos on a few with UEFI. No problems to speak of but I've never tried the scenario you're talking about.

=============================================================== From: wes ------------------------------------------------------ once you turn off UEFI (which you'll be doing either way), it behaves just the same as a legacy BIOS would. the OS doesn't care which one you have once it actually begins booting. it's this beginning that is the challenge. the method for turning off UEFI (or "secure boot") is dependent on the motherboard model. some won't even let you turn it off, meaning you will not be able to run linux on it, ever. google before you buy. -wes

But yes, if you plan to run anything other than Windows on any new MLB, you should determine if secure boot can be disabled, failing that, if UEFI can be disabled. If you can't do either, particularly the first, I'd avoid that manufacturer like the plague, and send the highest ranking email address I could locate and tell them why.

=============================================================== From: Ralph Edge ------------------------------------------------------ Just got a new laptop a month ago, was able to disable all the UEFI crap and get ubuntu installed, took me like an hour to get through it. -Ralph

=============================================================== From: Dave Brockman ------------------------------------------------------ -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Nothing wrong with UEFI... it's about time we retired the damn BIOS anyway. SRM was almost a complete *nix console, and that was early 90's!

=============================================================== From: "Alex Smith (K4RNT)" ------------------------------------------------------ SRM, OpenBoot and OpenFirmware FTW :)

=============================================================== From: John Aldrich ------------------------------------------------------ Looking at ASUS F2A85-M PRO. According to the manual, it appears that UEFI Secure Boot is only enabled if you select "Windows 8" as your OS in the BIOS config. The other option is "Legacy/Other UEFI", which I guess is for Win7 or earlier versions of Windows, or OS/2 or Linux. :D
