APPARATUS AND METHOD FOR BACKGROUND MEMORY TEST DURING SYSTEM START UP |
摘要 |
A system and method is provided for testing a computer system main memory during system startup. An initial block of memory (20) is tested and marked as valid or invalid during a startup sequence, with the remaining system memory initially marked as bad. An operating system and applications can be loaded into the initial block and operate normally, and a concurrent process is invoked to test the remaining system memory. This allows the remaining system memory to be tested and marked as valid during normal system operation. <IMAGE> |
