Memory Checkout
Customer diagnostics can eliminate defective memory so
no memory error code appears at power-on reset. After
you replace a defective memory module on the system
board or IC DRAM card, run Automatic Configuration.
Otherwise, the new memory will not be recognized. (If you
have to run configuration with your own diskette, be sure
the customer has all the correct option diskettes available.)
