Are you sure you want only 8086 instructions? 'pushd' is not an 8086 instruction. Neither is 'push imm'. Perhaps you want to select a more capable CPU? You need 80386 at least to get pushd, and/or 80186 to get push imm.

Judging from the rest of code I suspect that 16-bit PUSH is needed here. Just replace "pushd" with "push".

PS. You also need to pop the right number of bytes off stack with RET.
