The diagnostic test is described which provides the means to obtain data on the system's performance. The test is divided into five different areas: storage test, disk drive(s) test, ROM checksum test, screen buffer test, and sleep mode test. The storage test provides the means to test all the available memory (RAM). The storage test includes the following: - The system writes a checkerboard pattern "10101010" for all available storage (RAM). Then the system reads all the pre-written locations and checks if the pattern was success fully written. The system writes once and reads twice. - The system writes the complement of the checkerboard "01010101" previously written on RAM.
