There's 2 stuff patched on the DNAS image. One is the code that checks the DVD drive and extracts the disc ID to authenticate. It's put a code that aways output the same number and never go actually check the disc. Other is the modchip sniff code that is NOPed out (No OPeration is a CPU instruction that does nothing but takes space and is used to delete code without having to relocate other parts of the program.)
