I have a problem with the assembly code.
When I try  to send a pointer as an argument of an assembler
function, this function ignores the argument.

For example:

globl _flip

align 4

pushl %ebp
movl %esp,%ebp
pushw %es

movl 8(%ebp),%esi   /* Here is the problem. The function don't take
                       the pointer */

movl $0xA0000,%edi

movl _dos_seg,%es

pushw %ds

movw _dos_seg,%ds     

movl $16000,%ecx      

rep
movsl

popl %ds

popl %es

movl %ebp,%esp

pop %ebp

ret /* End */


If somebody knows something, please tell me.
