Chimera: Unified Chameleon Bootloader

Chameleon is an open-source project with numerous development teams working in parallel creating various branches containing new and exciting features. The source code is organized using the Subversion version control system (SVN). SVN repositories are comprised of a trunk and branches. The Chameleon team keeps the trunk as the 'stable' version, whereas side-line or experimental development projects are done in branches.

The problem is some branches have features that other branches don't have, and many new features are still not merged into the trunk. While this is an inevitable side-effect of rapid open-source development, it creates some confusion for new users. The result of multiple branches not only increases the difficulty of choosing which version of the bootloader to use, but makes it impossible to support certain hardware.

To assist new users, MacMan started a project to merge the best features from the branches into a new branch based on the latest Chameleon 2.0 RC5 trunk version. He's also added some new capabilities and fixes to support the latest hardware. 

Today we're announcing the results of that project, Chimera. This version consolidates the best features from all of the available sources for maximum compatibility across platforms. We've decided to use the name Chimera to differentiate the project from the Chameleon trunk. Our focus for Chimera going forward is to support current, new, and future hardware, not to add legacy support for older hardware. 

Chimera Includes:
  • All Current Features of Chameleon 2.0 RC5 Trunk 
  • Intel Sandy Bridge Support 
    • In mythology, a Chimera is a creature
      with parts from various animals. 
    • Based on valv r709 and enhanced
  • ATI 5xxx Graphics Support
    • All known Device IDs and Framebuffers
    • From Kabyl r748
    • Improved NVIDIA Graphics Support 
      • All known Device IDs
      • From valv r709 and other sources
    • Improved Core i CPU Detection and Reporting
      • Intel LGA Socket 1155/1156/1366
      • Hexacore i7 Support
    This project will be maintained with full source available shortly. We have asked the Chameleon team to add Chimera as an official branch. In the meantime, we've set up a dedicated area in the tonymacx86 Forum for bug reporting and feature requests.

    We've added Chimera to iBoot and MultiBeast as our default recommended bootloader. It contains all of the current features that were previously available in iBoot and MultiBeast along with these new capabilities. The updated versions are now available for download at

    This wouldn't have been possible without the Chameleon team, and especially Kabyl and valv for their hard work and effort. Stay tuned for updates!

      DSDT-Free and UserDSDT Solutions for ASUS Socket 1156 H55/P55 Motherboards

      I've always been a Gigabyte fan. When looking at last year's ASUS specs for 1156, standard Realtek ALC HDEF audio made Gigabyte the best choice. However, we recently picked up the ASUS P7H55-M LE. We figured it would be an important board to test, as many people buy ASUS, and would like them better supported

      I was astounded that when booting without a DSDT, most of everything just worked! No kernel panic on power management, built in USB hubs, SATA recognized- and best of all sleep worked! 

      As far as buying advice goes, because of the Sandy Bridge onslaught, there are some amazing deals on both Gigabyte and Asus 1156 stuff right now, and they're 100% supported. Here are 2 methods you can use for Post-Installation on most ASUS 1156 motherboards.

      Using a DSDT is not necessary for most ASUS Socket 1156 boards using a recent BIOS. Most implement RMH (Rate Matching Hubs) for USB, use VIA audio, and initiate Power Management on their own with no further tweaks. This means sleep works, even without DSDT edits! Please note that you'll still have to install audio, graphics, and network support separately.
      1. Backup and delete your /Extra folder
      2. Run MultiBeast
      3. Install choices below and reboot.
      ASUS 1156: UserDSDT METHOD
      In general, a DSDT is a helpful thing to have if you are planning on tweaking and optimizing. If you want to configure 2 graphics cards via DSDT graphics edit, or if you want to add support for HDMI (HDAU edit) you need a DSDT. To utilize AppleHDA instead of VoodooHDA for Realtek ALC8xx audio, you need a DSDT. Please note that you'll still have to install audio, graphics, and network support separately.
      1. Backup and delete your /Extra folder
      2. Download your motherboard's DSDT from the DSDT Database
      3. Place the .aml file on Desktop
      4. Run MultiBeast
      5. Select UserDSDT + System Utilities
      6. Reboot
      ASUS P7H55-M PRO - AMAZON / NEWEGG  $99.00

      Please report back in comments if the DSDT-Free method works for you!  Thanks!

      Apple to Allow Mac OS X Lion on Generic PC Hardware [April Fools]

      Apple announced today a stunning move to open up OS X to run on generic PC desktops. Founder and CEO Steve Jobs in a statement announced, "We have decided that we simply cannot produce a product that meets our standards and be priced between an iMac and Mac Pro. Our top engineers have researched this and determined that the solution of iBoot and MultiBeast is the finest solution available and will be included in Mac OS X 10.7 Lion."

      Stay tuned for details.
      April Fools from tonymacx86 and MacMan.
