Demand-paged executable files are really outdated now.  If you wish to
use them, your kernel has to be compiled for a.out support.  Most
stock kernels in distributions have module support for this, you have
to load the module binfmt_aout.o for this.

Please note that loading this module is not enough, you will also need
the old linker /lib/ld.so and old a.out libc which are not included
nowadays in the distributions.

Perhaps the only noteworthy a.out program for which I could not find
an ELF equivalent was ID software's DOOM.  Are you also stuck with the
same program?

Bye,
Lokesh.
