[syslinux] syslinux.com 6.02 Invalid Opcode under FreeDOS

_ Vbox 4.2.18 VM booted with FreeDOS floppy, kernel 2041, no 
config.sys, no autoexec.bat, no TSR's, no memory managers.

_ The booting floppy includes syslinux.com 6.02.

_ Two HDD images attached to the VM, MBR + 1 FAT16 formatted 
partition each.

Executing syslinux.com -i c: (or "d:") results in the following 
error:
"Invalid Opcode at AD04 5080 0206 5080 2021 3666 FFFD 0083 0000 5208 
0000 0083 0000".

The 2 relevant files (ldlinux.sys and ldlinux.c32) are copied to the 
destination volume anyway. The resulting volume is still not 
bootable.

A similar scenario, but with memory manager(s) will fail with 
different errors.

Hopefully this can be replicated and resolved.

TIA,
Ady.
