Show me your UEFI settings page - looking for functions

    I agree with JLyman.
    The BIOS interface is the SAME as on my older 100% BIOS and is also made by Insyde.

    The UEFI is added on top: seems a good explanation. But legacy mode (classic BIOS boot) comes in second place so, yeah, UEFI is more important as default choice.

    What we have here are between the first UEFI based BIOSes from HP and it's not excluded they'll modify and add extra options in the future. For stability alone I had already 2 firmware updates since September.

    However they still hide some functionality away. I've seen that by looking at extra options people unlocked at biosmods.com but that was by looking at classic BIOS options (will be available for newer version as well with increased demand). The new UEFI ones will also have advanced hidden menu's that are hidden for the sake of most users (ok, there are a few experts here and there but that's all). The normal users don't know what the settings do and can mess their configs pretty fast. UEFI has many options and most still evolve as newer functionality is added, it's still early for UEFI as intended to replace the BIOS for good BUT is pretty normal they don't apply all theory (specifications) into practice stating with the first versions you get.

    In my opinion it seems someone at Microsoft thought it would be a great idea if all Windows 8 users became test subjects. Almost as if they said, " Lets get people to use this buggy unproven technology and see what happens". I know it didn't happen that way but that's what it seems like. I have browsed many Linux distro forums and am even on some trying to get the likes of Mint 14 or Ubuntu to install and work properly under UEFI with secure boot disabled and have run into tons of troubles even the Linux old time experts have a hard time figuring out. You'll notice on those forums the first thing people with Windows 8 does is disable UEFI and switch to Legacy Bios mode. They don't want to deal with UEFI. I am one of the crazy ones who have spend a week fighting with these systems - and Ubuntu and Mint do have compatibility build in for EFI. ( I like the idea of UEFI's faster hardware access coupled with a fast 64 bit system so I stuck it out trying to make this work) One would think that these forums would be full of people with Windows 8 trying to get a Linux distro to install under UEFI but that isn't happening this time around. These Linux old timers are folks that are used to getting into the code in the systems and configuring the system they way they want to - yet, they are leery of UEFI. On one hand it's said Uefi is more secure than Bios but Bios is written in assembly language which hardly anyone uses anymore. UEFI is written in C which tons of people use. I think it's possible hackers have a better chance of exploiting UEFI than they do Bios for these reasons. One things for sure, these new adventures into Uefi are going to be a wild ride.

    Even if these UEFI's were fully functional versions with no Bios mode, it should not be possible for someone to mess up the system very badly (outside of using a hack/malware to attack the system) . There appear to be contingencies build in for this where the system would revert to factory default firmware and in the case of Secure Boot default PK's and datebase.

    Who said that? Well... it's said... legends... but I programmed a thing or two and can tell you that the programming language of BIOSes is not assembler nowadays. The assembler is in portions not entire code because it's too hard to follow.
    The used language is irrelevant and it's mostly C and C++ but watch out the slight differences.
    SO They even, use C and C++ to make BIOSes, actually the same BIOS makers are the ones adapting the UEFI in newer models, or you thought just for UEFI new companies will rise?
    The hackers will always be able to reverse-engineer in assembler no matter what the code is. Nobody programs in assembler anymore but that's a different story.

    Even if these UEFI's were fully functional versions with no Bios mode, it should not be possible for someone to mess up the system very badly
    No UEFI alone is pretty solid.
    I was refering to a BIOS with all possible options available: I don't think you've seen one otherwise you will complain for other reasons like too many options.

    I've seen HP BIOSes that expose the advanced menu and to be honest 70% of what's available there a normal, even more advanced user wouldn't understand. And there are options with "do not change" next to choice menu's: those are the ones you have to avoid because you'll mess things pretty badly if you touch them.

    If they hide most of the options is good thing.
    For your more choice-friendly UEFI you'll have to wait a bit more because it's just the beginning and you'll see other stuff coming along the way.

    I agree that a more advanced choice menu should be available, I have HP too. We'll just have to see what updates or fixes will be available in future versions.

    Some pre-production boards with the full UEFI feature-set exposed can have upwards of two hundred different things to tweak, most of it even I don't understand.

    Thanks for the updated info Hopachi. I supposed I read that about Bios being written in assembly by people who were pushing UEFI. Actually I think it was a youtube video telling of the differences between the two.

    Seems many Samsung models are bricking the systems when you try to run Ubuntu under UEFI with secure boot disabled. Booting Linux using UEFI can brick Samsung laptops - The H Open: News and Features Reading this it's not clear to me if this is an Ubuntu problem, a Samsung firmware problem or a hybrid with both.

    Bricking for those who don't know means permanently crippling the system where they will boot nothing, even Win 8 with Secure Boot enabled. It effectively turns the system into a brick, a door stop.

    You're welcome.

    The bricking is troublesome, I saw the article.

    For those Samsung laptops a fix has been found and probably the'll learn something about this and release a few updates on it:
    Samsung Laptops Bricked by Booting Linux Using UEFI

    Luckily those aren't entirely bricked. But Linux won't be recommended on them until they decide to do something about it.

    Confirmed by a MS Windows Engineer. Thanks.
    That explains even more why many options, irrelevant for the end-user, are hidden.

    A lot of it is specific stuff for Intel or AMD to test their chipsets with and are really only there to forcibly create new scenarios.
