BIOS Spotlight: (UEFI) Dell XPS 15z L511z

This article documents the exciting work being done by some of our top contributers in our forum. The modifications performed on systems like the Dell 15z reflect the most advanced examples of BIOS modifications done within our  community.  For more information, please visit the thread.
Phoenix SecureCore Tiano, used by Dell, is a tough nut to crack – we came to what we have today by taking little steps on a road that wasn’t smooth to begin with. Phoenix nor Dell have provided any information regarding SCT 2.0 and to this day the BIOS on these machines has not been upgraded to 2.3.1 which allows for ME v8 (brings IVB CPU support) and SecureBoot capabilities.

The number one utility in all of our research is without a doubt AndyP’s Tool, which can be found here. Huge props to him – without his tool our work wouldn’t be possible. Please note, that for some reason later versions of this tool such as 2.11 don’t seem to unpack the BIOS.wph’s capsule properly, so use versions prior to that if you are going to attempt doing some *magic* on your own. There have been a new Phoenix Tool release v2.12 but I have yet to try it, I personally still use 2.02 and it has been producing stable and working output.

HP Nettle2/3 COMPAQ IRIS8 and Acer Aspire E380 Unlocked RETAIL Bios

We finally have some really really exciting news. The battle for these common boards to have stable OC menus, voltage modification, Phenom II support, and a professional retail BIOS has finally come. Our most helpful members banana19 and MrTangoWhiskey have found an ABIT retail BIOS, that successfully flashes to all of the OEM boards mentioned with full control of voltage, OC, and has support for all Phenom I/II proccessors.

So before we get to specifics, a brief timeline on the modding proccess for this motherboard. This has been going on for over a year, and it has taken a lot of support and research to get this board where it should be. We originally started off modifying the HP BIOS for the board. we were able to get overclocking options from it, but the menu was very unstable and items were always floating on the screen. After about 8 months of searching for the solution within the HP BIOS, we realized that poor coding quality in the BIOS was unfixable, and it was time to find the retail fit. I had been doing research on this when a kind member on the forum pointed that this BIOS had all the goods. Its version numbers were similar, it had the same chipset (BIOS donated from ABIT board) and abit has always been known for having overclocking options. With this unlock, we have unlocked what we would see in a retail award bios. The most appealing features are control of AMD Cool and Quiet, Adjustment of CPU FSB, and even setting the voltage and memory timings.
