How to get the OF to equal 1

[Netherbeast]

How can I get the OF to equal 1 by adding 2 32bit integers?
This is what I tried:

.data
var5 DWORD 0ffffffffh
var6 DWORD 0ffffffffh

.code
mov eax, var5
add eax, var6
call DumpRegs

Adding -1 to -1 to get -2, this does not produce a carry with overflow.

try adding 1 to 07Fh (127) or 07FFFFFFFh

07FFFFFFFh is the largest positive value a signed 32 bit register can hold.

on the other hand if you just want to set the OF flag try:

(32bit)

pushf
pop eax
or eax,0800h ;set OF in eflags
push eax
popf
