     149        Running a multilib system means also that the kernel has to be
     150        configured proper. It is required that the kernel is able to
     151        identify and start binaries compiled for different architectures
     152        than the default. Setup the required parameter in the kernel

     156    [*] IA32 Emulation

     160      <para>Make sure that the option
     161        'IA32 Emulation' is set if you built support for the 32bit ABI.
     162        If you selected the x32 ABI or built support for both, also select
     163        'x32 ABI for 64-bit mode'. The option 'IA32 a.out support' is
     164        optional.
