Ensure that your computer meets the following requirements before installing Adélie Linux. On Windows, you may run the msinfo32 program to determine your computer's specifications. On a Macintosh, choose About This Mac from the Apple menu, and then choose System Report or More Info.

You will need at least a Pentium or Celeron compatible CPU, with MMX extensions. This includes most AMD (K5+), Transmeta, VIA, and other x86-compatible CPUs. A processor speed of at least 500 MHz is highly recommended for running interactive desktop applications; lower speed may be usable in text-only or server modes. All Intel and AMD CPUs with 64-bit extensions are supported by the Adélie Linux system. You will need at least a G3 or later CPU. The 603 CPU is not supported by this version of Adélie Linux. A processor speed of at least 600 MHz is highly recommended for running interactive desktop applications, but all G3 and G4 CPUs are supported. AltiVec/VMX is not required to run Adélie; however, software titles are increasingly taking advantage of processors with these extensions. You will need a POWER4+, or 970/970fx, or later generation CPU. You cannot use Adélie Linux on a POWER4 or earlier CPU. The Freescale e5500/e6500 and SPE processors do not have the required AltiVec/VMX extensions, and therefore will also not be able to run the 64-bit Adélie Linux. All 64-bit ARM processors are supported by the Adélie Linux system; however, some SoCs may need a custom kernel. For more information, see the AArch64 HCL.

Memory and disk space requirements depend on the edition of Adélie Linux you wish to use.

For systems with less than 96 MB RAM, it is highly recommended that you use the HorizonScript Executor in Target Mode on a computer with more than 96 MB RAM. For more information, see the section on Target Mode.
