TM check, IPL checksum check in ROM 37, optical disk device 22 check, magnetic disk device 27 check, keyboard 23 and mouse 29 check, optical disk 20 read/write simulation test (image data through test), etc. or will be done.

For example, discuss read/write simulation tests. That is, the CPU 34 first writes the original data to the page memory 40, compresses the written data using the compression/decompression circuit 50, and stores the compressed data in the main memory 38 via the buffer memory 40a.
Write to the free area of . Thereafter, the CPU 34 sends the data written into the free area of the main memory 38 to the compression/expansion circuit 50 via the buffer memory 40a, in the opposite direction to the flow of data during compression, and uses this compression/expansion circuit 50. The expanded data is written to the page memory 40. Then, the CPU 34 compares the decompressed data with the original data before compression to check for a match, and to check for code data errors, data conversion, etc.

As a result, if a code data error occurs in the read/write simulation test, the CPU
