Throughout the years, many "distros" were released for download over the Internet. These distros were copies of the Mac OS X installer disc modified to include additional components necessary to make the OS run on the non-Apple hardware. A prominent member of the community, JaS, released many distros of Mac OS X Tiger containing patched kernels. Some other popular distros are iATKOS, Kalyway, iPC and iDeneb. Distros have fallen out of favour as the OSx86 community grew, as new bootloaders were developed that made it possible to use actual copies of the OS X Installer.
When "Snow Leopard" was released, Russian hacker netkas created a version of Chameleon that can boot Mac OS X v10.6. The main problem was that many people were forced to modify DSDT or use kexts due to some specific issues. As soon as possible modbin and dmitrik released test versions of kernel that allow to boot Snow Leopard on AMD machines. Stable XNU kernels for v10.6 were released by Qoopz and Pcj. There are some popular builds based on Retail by the name Universal (Intel only), Hazard, and iAtkos. Since v10.6.2 Nawcom, Qoopz, and Andy Vandijck have been working on Legacy kernel for unsupported CPUs.
