Assembly command check_sum is not included in educational book in class rooms in usa. And more...
And I have weird error for a PPC laptop that has an older BIOS (weird alien protection). If i try to boot it with an OS CD (not DVD reading) that didn't do a checksum (i was doing MD5 on command prompt) then it throws a decrementer exception on the screen and it feels the system admin hit me.
