Hi, Look into /usr/include/asm/unistd.h header file.. This will list all System call nos. , which will go into EAX. Other parameters will be same as for that particular system call and will be passed in register EBX onwards Regards, Anil. "Ethy H.

I need to disassemble a fragment of code that calls int 80 with different parameters. Regards -- Ethy H.
