How do I store and use 32 bit values in 16 bit mode

Question

Am I allowed to use E*X registers in 16 bit mode? If not how am I supposed to store and use 32 and 64 bit values (DWORDS and QWORDS). I know about using ax and dx together to store a 32 bit value, but how do I address memory like that? I don't think I can do push [ax dx], or can I?

Any information how do this is greatly appreciated, I looked online and it seems I am just to uneducated to figure it out because nobody seems to have the same question as I...

Answer 1

Is it possible to use 32 bits registers/instructions in real mode?

The link above solved my question... I was just wording the issue wrongly in google.
