- Say Y here if you want to be able to execute Linux/Intel ELF

- this to work, you need to have the emulator /usr/bin/em86 in place.

- You can get the same functionality by saying N here and saying Y to

-
- You may answer M to compile the emulation support as a module and
- later load the module when you want to use a Linux/Intel binary. The
- module will be called binfmt_em86. If unsure, say Y.
