Memory Tests
Memory Test (All) - Eighteen test patterns are used to test memory locations. If errors are
detected, the address of the block the error was detected in is shown. During testing, these
diagnostics will also look out for parity errors and other exceptions. These will be added to the Test
Log as errors if encountered.
Memory: Pattern Test - The program uses several test patterns to test as much memory as
possible.
Memory: Parity Test - This test checks for parity errors on the memory bus during intensive string
transfer operations. If an error is detected, the address of the failed block is displayed.
