copy extended memory.

can anyone point me to an documenation on bios's
interrupt 15, ah=87. It is 'copy extended memory'.
I suspect the implementation I have is wrong, and
thus stops me from adding support for legacy
applications under LinuxBIOS.
Going over phoenix manual and Ralf Browns's
interrupt list, I know that
CX = counter
ES:SI = pointer to GDT
what is not clear to me is what does determine source and destination
of the copy. Would it just copy between first and second segment
(if so why it is not documented).
