Bill Gates puzzle

Oct 1st, 2007

[[ re-posted from the DesktopLinuxAsm mailing list ]]

<< Here is a puzzle for assembler guru's and anyone
who needs a diversion.

Bill Gates has spent the last year working on a virus to
destroy Linux. To complete his virus he needs the constant
of -4 in eax. His virus hides in the ELF header and at this
point he only has 2 bytes of program space left. All his
general registers are zero at this point.

How does Bill generate -4 in two bytes of code?

Warning, Bill Gates is devious, cunning, and so is the
solution. If anyone can solve this they will suffer exposue
on DesktopLinuxAsm web page and envy from everyone
who claimed it could not be done.

all the best, jeff >>
