    Sounds like EFI can't come too soon. I had no idea the BIOS had so many limitations.

    Will be interesting to see what it can bring to the table thought honestly i don't see the need to change things...but if its beneficial bring it on :toast: On a side note if this is ever adopted.....whats going to happen to companies like AMI and Phoenix? :wtf:

    I've run into to not enough ROM issues on my server in using the latest BIOS and my RAID card. Server hardware is especially borderline functional due to the limits imposed by the BIOS. I just hope this new stuff is backwards compatible in terms of capabilities. I also hope it has a unified and secure means to be upgraded.

    Do you mean secure as in TPM style secure? :confused:

    Hell no! :roll: I mean non-execute bit, secure memory blocks (read-only), and other technologies that dictate anything loaded on top of the BIOS platform cannot directly modify it--only read from it. It therefore prevents viruses or any software from doing permanent damage to the machine.

    TPM is an Infineon technology. It is basically a money laundering scheme like HDCP and DPCP. Worst. "Technologies." Ever. They help the corporations control how you use your electronics. They, in no way, help the consumer. Where the law should prevent such practices, the law (certain members of Congress) is actually trying to see this practices implemented. It is disgusting, appalling, and by every stretch of the word, offensive.

    :nutkick: ohh come on, your trying to twist what i said. I was simply stating i have yet to personally experience the supposed short comings of the BIOS so im in no rush to try to find something to replace it :p

    According to that article Foxconn aren't having any of it...

    ... >.<

    I like the idea of having access to the internet from within my 'BIOS' - features such as being able to troubleshoot when your OS goes bad, or for when you don't want to boot all the way into your OS. Being able to download another users (with the same components as yours) OC profile would be pretty handy for those that are having issues hitting a speed someone else has.

    Still - "If it isn't broken, don't fix it."

    I've very keen to see EFI implemented in upcoming motherboards, even if it does turn out to be a novelty.

    EFI trashes legacy support. Thats why I don't like Apple's lack of support in general.

    For me that isn't a problem.

    This is kind of interesting, might give it a go on my P5Q Deluxe after I read more of what it's about.

    As long as I can still overclock with it I'm good...

    Current EFI doesn't allow it, short of clock generating software. If you ran EFI-X you could but those are expensive hardware hacks to use PC hardware on OSX and has very limited hardware support.

    What kind of limits? I can't really think of any apart from the capability to boot from GPT disks, which usually isn't needed.

    EFI is supported in vista SP1 and onwards, so we're all heading there sooner or later.


    Its all down to how long it takes mobo manufacturers to release a board that uses it for the enthusiast community.

    I was booting from the RAID card and also had the itegrated RAID enabled. The card BIOS pretty much filled all the remaining memory allocated by the motherboard BIOS. The new BIOS was (I think) 4 KiB larger which prevented the card BIOS from being loaded.

    That sounds more like a bug/bad design than some limit that applies to the design of whatever standards a BIOS follows.

    UEFI = will be awesome. but not yet.


    i've heard it can have a mini OS and store drivers in there as well, so you do a "BIOS" (UEFI?) flash to update it, and you'll never need to worry about "F6" floppy drivers for RAID ever again

    want to repartition a HDD, or resize partitions? no worries, your EUFI has that built in!


    its got great possibilities, once they get their asses in gear.


    edit: hell, if someone went totally utterly hardcore, they could make the UEFI the main OS, and run virtual machines out of it for your other OS's.
    many cool, yet pointless things await!

    Making a BIOS the whole OS is not a new idea. All the 8-bit computers of the eighties had this and even the grown-up 32-bit Acorn Archimedes released in 1987 did it this way.

    Ultimately, removing the current BIOS restrictions and adding in certain flexibilities will probably provide the best balance.

    *yawn* When manufacturers actually get around to doing something about it, let me know. Otherwise it's the same discussion every couple years when someone brings up EFI :)

    but this is UEFI - now with 33.3% more letters than ever before!

    MSI released a UEFI (or was it EFI:confused:) bios for my P45 Platinum. I gave it a go but it was crap so I went back to the traditional one, LOL

    Heh, so it does. By the time any one takes notice we'll be up to UEFI-X Pro with Facebook support so that your system can update it's status and give out it's IP for causal encounters with other systems. Unfortunately...

    ... that feature and EFI as a whole still won't be implemented very well on devices other than Macs if the current trend continues :banghead: Oh well, I'm not really losing sleep over it. Just wish that if they're going to get it done - get it done! The possibilities go well beyond what the Tom's article mentions.

    I'm still not 100% sure I grasp the concept of EFI. I have been playing with PCs for 16 years, taught myself BASIC and HTML in middle school, taught myself C/C++ in high school, played with the Linux kernel source dode at 16 and built my own custom Linux install, recently got my A+, and have no idea what this EFI exactly is. It's like the EFI does nothing but read data stored by the operating system to get all its configuration? But then the computer needs to have an operating system installed or an OS disk somewhere with basic BIOS-like functions so it can boot? Trying to wrap my head around this.
