Abstract
An apparatus for providing management storage via a USB port of a computer system is disclosed. The apparatus includes a flash memory, a first and second switches, a first and second inverters, a designated port, and a controller. Coupled to the flash memory, the first and second switches are controlled by a main power of a computer system in a complementary manner. The first and second inverters, which are powered by a standby power of the computer system, are coupled to a respective control input of the first and second switches. The designated port, which is coupled to the flash memory via the first switch, allows data to be read from and written to the flash memory without booting up the computer system. On the other hand, the controller, which is coupled to the flash memory via the second switch, allows data to be read from and written to the flash memory by the computer system only after the computer system has been booted up.
