I knew some of those words

Generally good work - yay! Thanks. Suggestion: While most of us do genuinely appreciate a few humorously snarky asides and a bit of smart-ass Brit-Wit commentary in these kinds of presentations, please consider the possibility that compulsively tossing it in every 5 seconds might be, um, a bit much. Also, stopping to blow your nose occasionally would be *much* less distracting than the constant sniffling... But, again - nice work.

cheers I'm learning a lot

So basically UEFI solves a problem and creates so many other problems that the whole solution is rendered useless anyway :D

And how long until Intel and AMD processors refuse to execute firmware unless that firmware is signed? That's the next logical step for this "secure boot" stuff. After all, we can't have people hacking or replacing their BIOS to thwart secure boot.

6:57 this was done in April. In kernel >=3.3 these is a new option CONFIG_EFI_STUB which allows launching the kernel from the UEFI Shell itself, thus removing the need for a separate boot-loader.

unbuntu has no problem loading with uefi enabled but some operating systems require that you switch to legacy mode in the bis setup menu before they will boot.

I just recently used EFI to dual boot Win11 and openSUSE. I'm in the Windows Insider program and Win11 updates often. I noticed that the Win11 update process changes my boot driver order. I have a M.2 running openSUSE and W11 is on a 2.5 SATA drive. Any way to prevent this from happening?

this guy is the hope for the entire linux mac community. how do I donate to him so that I can get grub to work on a mac properly?

Microsoft has a very good history of trying to stop Linux progressing. He says that they have their point, but I think that there is a pretty big probability that they use secure boot mostly to make sure they dominate the market(cause from stats Linux and Mac grow faster than Windows now). I don't say that's the reason but it can be...

@thomasggpm AMD datasheets available to the public? I'll believe it when I see it. Where can I get the "AM3 Processor Functional Data Sheet", AMD document number 40778?

The Linux kernel has been able to use EFI at boot time since early 2000,[38] using the elilo EFI boot loader or, more recently, EFI versions of GRUB.[39] Grub+Linux also supports booting from a GUID partition table without UEFI.[13] The distribution Ubuntu added support for UEFI secure boot as of version 12.10.[40] Further, the Linux kernel can be compiled with the option to run as an EFI bootloader on its own through the EFI bootstub feature. see wikipedia UEFI and follow those sources.

11:30 ipad or iphone?

True, true, and true. But to be clear, some of your concerns are about Secure Boot, not UEFI. Various bootloaders have been able to load Linux on EFI for quite some time (rEFInd is particularly good; GRUB2 is a mess, but gets it done too), and the kernel itself can now be loaded directly from EFI. Matt's journal on Dreamwidth has a lot of info on the progress of Linux on UEFI and Secure Boot.

Microsoft has long done whatever necessary to kill the competition, but I'm sure there will be people to figure out how to run Linux (and other OSes) on UEFI boxes. After all, the current booting system is very DOS-based. I'm sure people could come up with a more OS-agnostic way to do things, but of course, Microsoft has no interest in doing that (in fact, it's just the opposite). But this rings of the "problem" with CPUs with built-in DRM.

@BernofMiracles I'm pretty sure the vendors don't really care. If they did care, we would have pretty well-written BIOS all around already, and there would be few bugs in Tiano itself. So we will be lucky if the vendors don't actually introduce new bugs to the system!

And after that, they won't execute software unless it's signed. Like mobile devices (android, ios).. then anyone who wants to write software will just have to register as a developer on their site and let them control distribution like Apple does now... what a Utopia we'll be in then!

And my new ACER laptop doesnt allow me to disable secure boot

Where is the POSIC C API port? Hardcore stuff!

But he makes valid points, i think biggest one is secure boot, it's very hard for linux to be sign due fact how open and elastic it is and casuals won't figure how to install unsign system (yes because they are stupid in those topics), which create barricades not only Linux but any other modular open kernel systems.

Is he talking about EFI or UEFI? or are they one in the same as far as this presentation is concerned?

Tiano is Intel's reference implementation of UEFI. UEFI Spec does not require the use of Tiano implementation. Besides, do not tribute implementation bugs as spec being "awful". No one system implements everything in the 1500-page UEFI Specification or use all 7601 files of Tiano code. The modularity and flexibility allow the pick and choose of the needed code, that is crucial to the faster boot time enabled by UEFI. Nobody is putting on a system a 100MB UEFI BIOS. UEFI can be in the 100K's.

in his defense some distros do not boot with EFI yet now im not saying its a bad thing just some haven't gotten around to it.

Yes and no. Coreboot can actually address more problems. One being you only need to maintain one driver that will work in both the BIOS and a linux OS. If also allows for pre-boot code audits. It can then load any multi-boot compliant payload directly.

Basically , And I will only say this one time Right here. - If The Software Cult of Microsoft wont Cooperate with the Free-Software Community ; It will basically Rip the Entire BIOS Frame. Seriously , it is not that difficult to do and it will be a Fatal blow to the entire MS Software Cult. - The more you try to control ; the weaker your System Becomes , and this is common knowledge. Microsoft is basically Shootin it self in the foot and the Aim is Raising towards the Tempel of the Head. - So thank you MS for killing yourself and Strengthening the Free-Software Community by the Boot Camp you call Windows (it is a intelligence test). We are just getting smarter here.

Nice. This video actually plays in youtube html5 mode. guess it has a webm version.

This is such a mess. Perhaps OSes will go more into visualization (with all the performance hits). Maybe OSes have to move into two categories where specialized host oses (slim and compact) host Windows, Linux and such to run in their own black boxes.

I don't know why I'm watching this, but, hey it's fun

Parted Magic does its job on UEFI, but it's too damn complicated, being based on Slackware

Isn't this precisely what Coreboot is set to address? Methinks everyone should get behind this project and make sure the OEM are compatible.

why should boot services ever end?

UEFI. Used by Microsoft. As their Bank Manger said " #Fud "

This guy seems to have been beaten, broken, had his spirit eroded down to nil and then fled into sarcasm and sardonic remarks. Not that I mind, but I do feel kind of bad for him.

Stop me if I'm wrong but being a Linux professional involves being a better programmer than the 'commercial' companies but not being told about all the problems the commercial companies already know about and have already worked past. I realise as I'm typing this that everyone already knows about something so obvious but my point is that if it's so obvious why can't something be done about it? I don't mean free access to proprietary code but free access to proprietary bug reports and suchlike.

I know that it's a Linux conference, but it would be nice to acknowledge the ramifications of UEFI for Windows users. I have worked on several Win 8/8.1 machines for clients, and the one problem I run into is that Win 8 trusts UEFI for booting. So, for example, if the machine won't boot the OS, you can't boot a CD. Thanks to UEFI, those options don't exist in a factory machine. Sure, you can make it boot from CD/USB, but only if the OS boots and you know what to do to change the boot options. I'm a Windows fan. I like the balance of control v reliability (Linux v iOS comparison?). But when a machine sticks in a restart loop, or won't boot, or has any serious hardware problem, booting a USB with my tools on it is the simplest option. UEFI means that, by default, Win 8 thinks its booting when it isn't!

Just got involved with UEFI, took me by surprise, after 5 days still do not have a working system, win7 wont install 64bit ver, xp fails etc. as for linux i managed to get the live cd to work, but appears to be a graphics problem in all cases. May give up and contact supplier for help. I am aware of whats required. I tried running setup for win7 with ext uefi as recommended, but all failed, starts to load files as normal but then fails abruptly. UEFI shell appears to work similar to dos, but my ITX system NOGO. May stick with my existing dual core amd64 by installing to a smaller case. A software developer friend of mine heavily into coding condemned it due to linux problems. As far as he is concerned Microsoft are stitching us all up, does not look good for linux.

EFI was deployment for the HP itanium hardware.

It is top down "I tell you what you should run on your pc" VS bottom up "we want to be free"

Also, again stop me if I'm wrong, but the irony is that no one ever did anything with the BIOS (or indeed understood half of it) that was ever useful even if the nerdy types fiddled around with it (e.g. parallel port settings) instead of just getting on with using the computer (me included.) So, UEFI is that with pretty pictures to please the kids yes? Or is UEFI immensely important with modern hardware & includes detailed documentation for the stuff you didn't look up in the motherboard manual?

Yeah, you have no issues with UEFI and Windows XP/7 because the developers had a political/commercial agenda and slanted the whole thing towards Wintel and against other OSes, that's part of what he says in the talk, if you actually listened to more than a minute or two (function names starting with WIN, etc.). UEFI is a biased bios, jumping thru hoops to preserve Wintel market-share.

Dude got pwned my Linus recently. :D

"technobabble" "laughter" #observer: "I'm in Startrek"

MS play dirty games trying to control every pc on the planet. Both my kids are teenagers and 2 years ago I installed on their PCs linux alongside windows. Although both game fans now open wins only for games and are both fans of linux because they understand the difference in stability, speed, safety and power of the 2 OS. I dont think MS will have any luck finally

I don't believe you, because Windows 8 mandates that you can. Can you just not get to the firmware, because on my Acer laptop to get to it I had to go under an option in Windows 8 called Advanced Startup. Once I got there though, there was an option to enable accessing the multiboot menu and formware settings by pressing F12, an option to disable SecureBoot, and even an option to browse FAT32 filesystems (what EFI uses) and select files to sign so they can be booted by SecureBoot, like Linux.

BIOS? You mean UEFI?

UEFI centralizes your points of failure to one single point.

Hmm ok so GG started blocking links so time to disguise. HyperTexTransPort colon slash slash coreboot org

impossible to listen to. Thinks about what to say next... starts speaking extremely fast, stops midway, goes back, resumes, holy shit he is worse than a first grader answering "what did you do today at school?"

No machines can host a 100MB UEFI BIOS on earth today. Not even servers. Flash part physics in play here. Besides, not everyone is using the same Tiano code. Even in Tiano there are EDK and EDK II. Let alone all the BIOS vendors. Besides why are the Linux guys worry about the actual BIOS code in the first place, whether 1 file or 7600 files? Linux consume APIs provided by BIOS, Linux does not produce BIOS code.

test

You're trying for something better than Ubuntu? You're not exactly aiming for the moon, are you?

while UEFI = ALIVE newpc = 0 if newpc = 0 printf NO NEW PC FOR YOU else printf WATCH THIS AND LEARN HOW TO GET AROUND SECURE BOOT To bad its alive and not going anywhere, causing the average user to loose out and be afraid to switch over to linux.
