Apparently, the slides from a past semester have an error in them. When you're getting the device instruction to start an I/O operation, you want to access the process control block's (rb->pcb) segment table (segtable). You don't want to use MEMMAP. MEMMAP is the memory from the cpu's point-of-view. A blocked process keeps track of its segments with its own segment table.

Second, the variable "dev" should be calculated by taking the instruction's opcode and subtracting OPCDSIZE. Omit the additional minus 1 found in the supplemental (not my slides) slides.

Many of you have come in with this same problem. Sorry the slides contained an error.
