Memory Checkout (8551)



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 kit, run 5. Automatic configuration or 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.) Power-off the computer before removing or replacing parts.
