ABSTRACT:
When connection between a computer body and an expansion unit has been detected, a system BIOS detects whether or not a storage device in an access lock state exists in the expansion unit. If a storage device in the access lock state exists, the system BIOS issues APM event to turn on a high-order driver for requiring a user to input a password through the operating system. The system BIOS supplies the input password through the high-order driver to the storage device and returns, to the high-order driver, a result of determination of releasing of the access lock of the storage device. If the result of the determination of releasing is affirmative, assignment of the resource to the storage device is performed.
