The problem is your format is completely wrong. 

The 'rep movsd' instructions automatically use the es:edi pair as the
destination, and the ds:esi pair as the source. 

What you need to do is move the segment and offset values into the
registers first, and then execute the rep movsl instructions.

This is some pseudo code to show you what I mean:

	mov		source_segment, %ds
	mov		source_offset, %esi
	mov		dest_segment, %es
	mov		dest_offset, %edi
	mov		count, %ecx			
	rep
	movsl

Note the rep and the movsl are on seperate lines.

Leathal.
