摘要： In connection with a computer system, a method for performing efficient memory testing of large memory arrays in a single contiguous block is disclosed. Memory test code normally residing in ROM or flash memory is copied to a processor's primary (L1) cache via the processor's test registers. Once contained in the processor's L1 cache, the memory test code is executed to test all of system memory in a single, contiguous block, allowing a more complete test for memory-related faults. The method results in greatly improved performance because the only accesses external to the processor are memory test accesses, and because cache memory is typically high-speed as compared to RAM, ROM or flash memory.

摘要： Disclosed are a system and method for providing user-invocable, non disk-based diagnostics routines for a personal computer. The method comprises the steps of (1) storing a diagnostics routine capable of performing diagnostic tests on portions of the personal computer in ROM, (2) monitoring a status of a reset button coupled to the personal computer and (3) executing the diagnostics routine if the reset button is pressed twice within a preselected period of time. The disclosed system and method allow a user to control the invocation of a diagnostics routine that needs a minimum of functioning computer hardware to execute.
