: INITIALIZE CARD

This section will ini tialize the memory space to all ones or all zeros and clear the syndrome register( s) of all memory controller( s) in the system. Step 12 will write all zeros to memory then read it back and verify proper storage. Step 11 will write all ones to memory then read it back and verify proper storage. Step 10 will clear the memory controller syndrome registers.

This section has three steps. as shown below. The user can select any combination of steps.

Step 10 Initialize memory controller(s) Step 11 Initialize memory to alIi's Step 12 Initialize memory to all O's POSSIBLE OUTPUT MESSAGES:

Memory Diagnostic 4·11

The N[enl0ry Controller tables below show how MEMDIAG will display memory configuration for 9000/720- TjO. 9000/8xi, and 3000/9x7 machines. ~Iemory array cards on these machines are configured in pairs (labelled as OA. OB. lA, lB, etc.). Each memory array card can be doubl(>-sized; it is possible to disable half the memory on each card in a memory array pair which is double-sized. The operating system treats a double-sized memory array card as if it were a two- bank memory array card. and assigns two SPAs to it.

MEMDIAG treats a pair of slot numbers (e.g., 0 and 1) as a virtual memory controller. Each of these virtual memory controllers controls two memory array cards (A and B) per bank.

This rneans that the user will see the same virtual memory controller displayed twice for a two-bank nlemory array card. A user can locate a memory array card by combining the virtual memory controller number (slot O. 1, 2, etc.) and the memory array (A or B) together to form a slot number (OA. OB, lA. lB, etc.).
