<p>PURPOSE:To provide an information processing system capable of constructing a system having a number of IO and starting the whole system normally even if the only power source of a main body system is turned ON-OFF. CONSTITUTION:An IO system 20 is provided with plural of IO 21, an IO bus 22, an IOP2(IO processor) 23 and power source for an 10 system (PS2) 24. Further, the system is provided with a signal generation part 25 detecting that main body power source 13 of a main body system 10 is turned ON based on a power source ON decision signal 111 transmitted from the main body system 10 via an interface 16 and generating a power source ON clear signal 110.</p> |
