Speaking of DOS: Every version I know of (although being only
the 4.0 through 6.2 lines of MS and DR's versions) came with a
program called debug.exe. If one doesn't mind (e)ntering the
data (maybe by means of a clipboard or selection tool when of the
lazy kind) one can (u)nassemble any hex dump coming across. But
then: debug.exe doesn't know about processors beyond 80286 or
doesn't even know this one's features. So chances are you won't
see i386 code in any readable form and being "db"ed instead. :(

Just FYI if you don't get what you want with objdump(1) -- I
don't know well this can cope with formats _not_ being produced
by cc(1), ld(1) or ar(1), i.e. not being a supported executable

If you don't understand or are scared by any of the above
ask your parents or an adult to help you.
