custom boot loader

HI all,

I need to create my own bootloader that will watch for a "start programmation" sent via a PCI interface

to start downloading a new program to flash.

At the moment I can achieved writing stupid data to the flash from a DLL via a PCI.

I am wondering which is the file that is written by the ALTERA flash programmer to the flash. Obviously

it is not the *.flash file. This *.flash seems to be converted in another format which is then written to the flash.

What is the file that is written in the flash after conversion of the *.flash ???.

I am really stucked now http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/unsure.gif

HELP !!!!.
