Abstract
A computer apparatus includes a main memory, a first memory diagnosis unit that determines a faulty area in the main memory by executing a first memory diagnostic program, and a storage unit that stores a relocatable second memory diagnostic program. Moreover, the computer apparatus includes a second memory diagnosis unit, that loads the second memory diagnostic program into areas of the main memory other than the faulty area determined by the first memory diagnosis unit.
Claims18
A computer apparatus including a main memory, comprising:
- a first memory diagnosis unit for determining a faulty area in the main memory by executing a first memory diagnostic program;
- and
- a second memory diagnosis unit for loading sequentially a plurality of memory diagnostic programs from the one with smaller program size into areas of the main memory other than the faulty area determined by the first memory diagnosis unit, each of the plurality of memory diagnostic programs being larger in program size than the first memory diagnostic program and being loaded into areas of the main memory other than the faulty area which is re-calculated and determined, by the second memory diagnosis unit, using the previously loaded memory diagnostic program among the plurality of memory diagnostic programs.
A method of diagnosing a main memory in a computer apparatus, comprising:
- determining a faulty area in the main memory by executing a first memory diagnostic program;
- and
- loading sequentially a plurality of memory diagnostic programs from the one with smaller program size into areas of the main memory other than the faulty area determined by the determining of the faulty area, each of the plurality of memory diagnostic programs being larger in program size than the first memory diagnostic program and being loaded into areas of the main memory other than the faulty area which is re-calculated and determined, at the loading, using the previously loaded memory diagnostic program among the plurality of memory diagnostic programs.
A non-transitory computer-readable storage medium that stores therein a computer program for diagnosing a main memory in a computer apparatus, the computer program causing the computer apparatus to execute:
- determining a faulty area in the main memory by executing a first memory diagnostic program;
- and
- loading sequentially a plurality of memory diagnostic programs from the one with smaller program size into areas of the main memory other than the faulty area determined by the determining of the faulty area, each of the plurality of memory diagnostic programs being larger in program size than the first memory diagnostic program and being loaded into areas of the main memory other than the faulty area which is re-calculated and determined, at the loading, using the previously loaded memory diagnostic program among the plurality of memory diagnostic programs.
