elksemu - Embedded Linux Kernel Subset emulator
/lib/elksemu program [arguments]
Elksemu is a program that allows 8086 ELKS programs to be run under Linux-i386. These programs can be compiled using the bcc(1) C compiler. It is not usual to invoke /lib/elksemu directly, either the simple patch or kernel module distributed with it will cause the kernel to run /lib/elksemu with the correct arguments whenever the user tries to execute an ELKS executable directly.
There are no flag options to elksemu, the first argument is the name of the program to run the rest are arguments that are passed to the Elks program. The elksemu program is normally installed suid-root and in this event it is able to run execute only (chmod 111) elks executables and act correctly on the suid permission bits on those executable. This may be considered a security hazard so elksemu does not have to be installed suid-root.

Elksemu is incomplete. The program may still have security bugs! Jan, 1997 elksemu(1)
