dpreed / Pure64

Pure64 is a 64-bit software loader initially created for BareMetal OS. The loader gets the computer into a full 64-bit state with no legacy compatibility layers and also enables all available CPU Cores in the computer. If you need a quick way to boot a 64-bit AMD/Intel based computer that will enable all available processors and load your software then Pure64 is ideal. Pure64 keeps an information table in memory that stores important details about the computer (Amount of RAM and memory layout, number of CPU cores and their APIC IDs, etc). The Pure64 loader has been released separately so others can use it in their own software projects.

Building

The only requirement for building Pure64 is NASM (The Netwide Assembler). In Linux you can probably download it from the distro's repository. If you are using Windows or Mac OS X you can grab pre-compiled binaries here in the macosx and win32 directories, respectively.

Build scripts are included for Unix/Linux and Windows systems.

Mac OS X/Linux: ./build.sh

Windows: build.bat

Notes

Building Pure64 from source requires NASM v2.10 or higher; the version included in the OS X 10.10 Developer Tools is not recent enough. - Seriously, Apple? NASM v0.98 is from 2007!!

If you use MacPorts, you can install NASM v2.10+ by executing: sudo port install nasm
