Random information on the term “E-I-E-I-O”:

Enforce In-order Execution of I/O, or EIEIO, is a machine code instruction used on the PowerPC computer processor which prevents one memory or I/O operation from starting until the previous memory or I/O operation completed. This instruction is needed as I/O controllers on the system bus require that accesses follow a particular order, while the CPU reorders accesses to optimize memory bandwidth usage.
