Where can i get "advanced_boot_copier.c " file?

Hi all,

Where can i get "advanced_boot_copier.c "?

In an458 document of niosII_docs_8_0, it guides:

"The source code for the default boot copier is included with the Nios II

embedded design suite (EDS) in the <Nios II EDS install path>/

components/altera_nios2/boot_loader_sources directory, or in the

Nios II literature page ( www.altera.com/literature/lit-nio2.jsp) with this

document."

But i did not see the source code such "andvanced_boot_copier.c" and "advanced_boot_copier.h "

(an458.pdf document is about NIOS boot methods)

Thanks for your helps in advance!
