Abstract
An information processing apparatus includes a rewritable non-volatile memory with first and second areas for storing a boot program, a central processing unit (CPU), a downloader for downloading a new boot program from outside the information processing apparatus, and a status monitoring circuit. The status monitoring circuit includes a status memory for periodically storing a boot selecting signal, which may change in response to a detected error. The status monitoring circuit generates a reset signal for rebooting if an error is detected and also selects a boot address, which indicates whether the first or second memory area should be used for the reboot in response to the boot selecting signal.
