Abstract
Method of passing inbound messages to an I/O processor's local memory. A message is received in a messaging unit within the I/O processor. The messaging unit is read to fetch the message. A free local message frame address is retrieved from the messaging unit. A direct memory access unit coupled to the messaging unit is set up. The message is then copied into the I/O processor's local memory.
