Ezdiag is a simple system configuration checker. The utility is a safe, non-destructive way for you to verify the configuration of your older AT compatible computer, and to specifically test the hard drive/controller subsystem. Upon loading the program, the low-order RAM pointer bytes are presented to the screen. The machine's power-on self tests test installed peripherals, and if valid ones exist, the tables are updated.
