A system and method for unlocking storage drives during the transition from a low power state to an operational state in a computer system is disclosed. During initiation of the computer system, a password for each password-protected storage drive is saved to a memory location in the computer system. During the transition from a low power state to an operational power state, the password associated with each password-protected device is retrieved from the memory location on the basis of the unique identifier associated with each storage drive and applied to the storage drive for the purpose of unlocking or making the storage drive accessible.

Bus numbering management for an information handling system, such as a personal computer, is provided by interfacing one or more selectively hidden devices with one or more buses through either a hardware or software implementation. If an inactive bus becomes active, then disabling of a selectively hidden device interfaced with another active bus provides a bus number to the newly active bus. For instance, if a graphics capability is added to a computer system through a PCI bus, a PCI bridge associated with a second PCI bus is disabled so that the PCI bus number for the portion of the second PCI bus between the chipset of the computer system and the PCI bridge is available for use as the PCI bus number for the PCI bus associated with the graphics capability. The PCI bus number for the portion of the second PCI bus between the PCI bridge and existing peripheral devices is available for use for both portions of the second PCI bus. Thus, peripheral devices associated with the second PCI bus will continue to be recognized by the operating system as associated with the same PCI bus number. Alternatively, instructions associated with the PCI bus controller enables or disables a virtual device by handling input/output accesses.
