how 2 modify stage2

[Sandeep Dhull]

 i am in a big mess...am working on a project to modify grub to introduce dongle based password authentication instead of the conventional password security of grub. i need to modify stage 2 for that but this is where the problem comes. i am not able to understand the code of grub stage 2 because,

1) the code has a number of c-functions. i was not able to find the body of the functions.only the fucntion declaration could be found in the header files.

2) in the line

       if(!auth && password)

    what is password. i was not able to locate its declaration anywhere.

kindly give my problem a thought...
