====== Build architecture setting ======

===== Name =====

    buildarch

===== Details =====

^ Type                | [[:cfgtype:string|String]]            |
^ DHCP option number  | not applicable                        |
^ ISC dhcpd syntax    | not applicable                        |

===== Examples =====

=== Display the build architecture ===

    iPXE> show buildarch
    builtin/buildarch:string = i386

===== Description =====

Specifies the CPU architecture for which this version of iPXE was compiled.  Possible values are:

^ ''i386''    | 32-bit x86 CPU   |
^ ''x86_64''  | 64-bit x86 CPU   |
^ ''arm32''   | 32-bit ARM CPU   |
^ ''arm64''   | 64-bit ARM CPU   |

  * ''[[:cmd:cpuid]]'' command

===== Notes =====

The build architecture does not necessarily represent the architecture of the machine on which iPXE is running.  In particular, a version of iPXE built for ''i386'' may be running on a 64-bit machine.  You can use the ''[[:cmd:cpuid]]'' command to determine the architecture of the current machine:

    cpuid --ext 29 && set arch x86_64 || set arch i386
