This kernel patch allows you to run Linux-8086 executables transparently
on a Linux-i386 (1.2.13) system.
It requires V0.0.2 or better of elksemu in the file "/lib/elksemu".
If you are using kernel 1.3.* or later try the module: binfmt_elks.o
If you are using 2.0.36, 2.1.43 or 2.2.0 and later use binfmt_misc.
