<p>PURPOSE:To prevent a read error due to an IPL action by controlling the IPL (initial program load) action by means of hysteresis data of a temperature. CONSTITUTION:A power control part 13 is connected by a temperature sensor 1 in a magnetic storage device 20 and a signal line 6, and it stores temperature data into an internal memory at every prescribed time as a fetch hysteresis. When the instruction of power supply and IPL is given from a control display part 14, the power control part 13 reads present temperature data through the signal line 6, compares data with a specified use temperature range and judges whether it has passed a specified acclimating time. The control part 13 judges whether to immediately output the IPL instruction to SVP9 or to hold the IPL instruction until a temperature condition is satisfied according to the result. Thus, the read error is prevented from occurring since IPL considering the acclimating time can automatically be executed.</p> |
