Microsoft discussed the upcoming changes to Windows 8's boot process at BUILD last week, but Matthew Garrett, a mobile Linux developer and blogger at Red Hat has pointed out that the company's new requirements could be used in ways that harm the Linux community. One of Microsoft's new rules for Windows 8 is that any company that ships a windows 8 device must enable UEFI secure boot.

Secure boot uses signing keys to ensure that only verified, trusted hardware (and associated drivers) are allowed to boot the system or run once the system has booted. There are separate sets of keys for the boot process and OS/firmware communication. Garrett writes:
Quote:
An OS vendor cannot boot their software on a system unless it's signed with a key that's included in the system firmware. A hardware vendor cannot run their hardware inside the EFI environment unless their drivers are signed with a key that's included in the system firmware. If you install a new graphics card that either has unsigned drivers, or drivers that are signed with a key that's not in your system firmware, you'll get no graphics support in the firmware.

Microsoft is becoming more like Apple in such ways I do not like. I see lawsuits coming on.

“For the enthusiast who wants to run older operating systems, the option (disabling secure boot) is there to allow you to make that decision,” said the Microsoft blog post. (The statement didn’t specify whether this is a reference to older versions of Windows only or if it also applies to Linux and other operating systems.)

Linux enthusiasts will make a UEFI version of GRUB, which supports Windows 8 then. Or Microsoft will create something like Boot Camp.

This.

If I'm reading it's just safety. Leave it on for end-users... Then either have boot-camp like features or a switch to turn it off for more advanced users. I doubt Microsoft will go Apple on us and lock it all down.

1 buy a 3rd party mobo AMD has long been a supporter of Linux so any AMD mobo should be good

2 remember how at first Linux didn't support SD cards then they reversed the SD interface and that got Linux support for SD cards..
yah the same things is gonna happen to secure boot

besides that theres no such thing as secure just ask sony about the PS3

They've already got similar features optionally in Windows 7, Bitlocker will get REALLY whiny if you modify the boot loader or boot parameters. Presumably the point is to try to make rootkits and other exploits more tricky, or this is part of some kind of DRM system licensing agreement.

Smartphones have had this for years and they've always managed to hack past it anyway, but I'd hope no OEM is stupid enough to not allow users to disable this. I'd certainly be [censored] off if my laptop stops booting because I replaced the hard drive and the new is not an exact replacement.

I believe people are working on UEFI support for GRUB. I doubt they'll add this to LILO though.

GRUB has supported GUID partition tables for a long time so I can only assume that means it also already supports UEFI booting.

EDIT: Found elilo (started 2003), Fedora has support as of 2009, also found this: https://wiki.ubuntu.com/EFIBootLoaders
Just remembered that Intel Macs all have some sort of EFI, so anyone running Linux on a Mac since then has had some kind of EFI bootloader.

It should say "Intel's UEFI Rules Could Be Used to Block Linux"

Yeah it might have taken a long time but the PS3 security eventually broken through. The Geohot incident I find was avoidable and was very brash and illogical of Sony. Geohot may have been the one to enable homebrew, which only made the PS3 better but the person they should have sued were the people who created the software to rip the games off the discs and make them playable on the PS3. Apple tried to beat Geohot in a similar case but failed, the court did not seem to grasp the word "precedent" in the Sony vs. George Hotz case. In all technicality Geohot, in my opinion as a law student, should have won against Sony or at least had been able to come to a mutually beneficial agreement. Sony fired a missile at the wrong target and still claimed victory.

True that. Thought EFI was something relatively new being worked on besides the Intel switch in 2005/2006
