Abstract
A host controller performs a centralized controlled over the operation of an information processing apparatus as a whole. Codes which are read out for booting the information processing apparatus are stored in a ROM in advance. The host controller copies the contents of the ROM into a high speed storage element and reads out the storage contents of the high speed storage element to boot the apparatus when a V,power supply is turned on after the V,power supply is once turned off. This allows the apparatus to be booted based on the contents read out from the high speed storage element which can be read much faster than the ROM.
