    Your info on the graphics cards is basically what I have seen, but I could have missed something. Since the latest 600 series cards don't have this, GOP support for UEFI booting has been ignored (I can't believe they forgot or overlooked this.)

    The basic point of UEFI firmware is a replacement for the old BIOS firmware, which is overdue. The GUI that UEFI firmware provides is only one new feature that it brings to the PC world. Other features it has is secure booting, but these two things are just a beginning. BIOS firmware is (I think) limited to 1MB of space for its code, Option ROMS, etc. UEFI firmware is 8MB, so there should be more room to use for OROMs, etc. IMO, it is to early to decide that UEFI firmware capabilities are no big deal, we've barely scratched the surface of using it.

    The reality of UEFI usage today is that 99% of people with boards that have UEFI firmware are only using its GUI feature. All these UEFIs contain a Compatibility Support Module (CSM) that is enabled by default, which causes the UEFI to function as if it were a standard BIOS, I call that BIOS emulation. AFAIK, the first generation of mother boards with UEFI firmware are not even able to disable the CSM. While UEFI booting support goes back to Vista, how many people know it exists? I didn't until very recently. Plus it was not until Windows 8 that the secure boot feature is supported.

    The first use (need) for the GPT partition table is to allow addressing of disks larger than 2TB. That is caused by the MBR's limit of using 32bit addresses. So while your PC may support 64bit OS's and applications, MBR disk formatting is 32bits. Do we really want to stay with that?

    UEFI firmware acceptance reminds me of the use of AHCI drivers, the features they have are really useful, but we don't understand them all yet. It took until 2010 for AHCI to be the common default SATA mode, but it was designed long before that.

    I don't know enough about UEFI firmware to describe it properly, but it's not just a gimmick, it's been available for years but we are only starting to use it.

    Its a pretty BIOS with flowers, rainbows, happy thoughts.

    That's only Evega, I haven't seen anything from MSI, XFX, Asus, see, we are coaxed into all the hype, the thrill, but no ba lls to back it up or use it.

    Just as we see an OS get faster boots, SSD's giving real fast boots, we get Ultra boot WTF. How about we get things when we need then.


    When they make the BIOS so we can add features, ROMS with ease, be able to control fans better and actually have them run at what we set them at, then its a real nice BIOS.

    AHCI didn't matter, a junk HDD can't even break SATA 1, then you had all the people who saw SATA 3 and thought it was going to be amazing and had no clue it was all just for compatibility.

    People asking, I got a SATA 3 HDD why am I getting only 100MB speed ?, because you were fooled.

    Just like with enabling 2TB, we are going to SSD, where was this when we had HDD's ? tell me. ROLOL


    We need someone who has a computer telling them how it should be, cause right now, its like they never had one. We had a major intersection and highway, it was a huge cluster mess, later we found out the engineer didn't have a drivers license.

    OMGosh, you want to equate SATA III HDDs with UEFI firmware? You're at least partially messing with me, I hope...

    Consider that BIOS firmware only works at the 16bit level, and therefore can only address system memory with 16bit addresses. It can't even use 4GB of memory. UEFI has 64bit addressing, is that just smoke and fast booting?

    A little, but the main point pushed is the GPT 3TB, how many 3TB SSD's do you have ? lol

    The memory is a huge difference, which gives a hugs plus, the interface which can go into all kinds of faces, settings . We see speed, maintenance, business advantage.

    Secure boot, don't really have an opinion.

    The disadvantage is attacks, there will be attacks, no matter what is done, software will be attacked.

    I also hear with the future we might not have a socket.

    I must say that the type of software secure boot protects a PC against, false drivers and OS boot loaders, doesn't seem to be what the typical malware is.

    The commonly used MBR is limited to four partitions per disk, and a size of ~2.2TB disk size. GPT extends that to limits of disk size far beyond what will ever be used by our current file systems, they will be long gone before GPT partition sizes are obsolete. BTW, the user file system used on a GPT formatted disk is NTFS. GPT only replaces the MBR. MBR was introduced in 1983, and came into use not long afterwards. An update to this ancient, in computer years, method of storing the partition table of a storage drive is long overdue. What other 30 year old complex data structure design are we still using, or want to use?

    GPT and UEFI booting exists, is being used, and will replace MBR and BIOS booting. You can't boot to a drive larger than 2.2TB without using a GPT partition table, and UEFI firmware. That can't be done with BIOS firmware. Newegg currently lists 46 HDDs of 2.5TB and larger. There likely would be more is PC's could boot from them, which is finally available to the common PC user, with Windows 8 and UEFI firmware on laptops and desktop mother boards. MBR and BIOS are holding us back.

    The world of PCs is an odd mix of the old and new, great, modern hardware is available (CPUs, memory, SSDs, graphics), with software lagging behind (32bit OS's still exist), and some of the most basic things, like the partition table of a storage drive, is far behind. GPT and UEFI is not just new and exciting due to marketing, they are updates to two of the oldest pieces of the PC puzzle. Frankly, it's about time.
