Abstract: Apparatus and method (200) for updating firmware in a chipset having a chipset microcontroller and a chipset memory. The chipset microcontroller is placed in an inactive state (208), such as during a boot reinitialization sequence. A host microcontroller writes a firmware image, representing updated firmware for the 5 chipset microcontroller, directly to the chipset memory (210) using an SPI (Serial Peripheral Interface) connection. The host microcontroller reads back the transferred firmware image from the chipset memory to verify a successful transfer of the firmware image (212). The chipset microcontroller is subsequently transitioned to an active state to execute the transferred firmware image (214). The chipset may form a 10 controller of a computer peripheral device, such as a data storage device. The firmware image may be supplied to the chipset memory using an HID (Human Interface Device).

Abstract: Apparatus and method for distributing power to a host computer (112). A first serial cable (145) establishes a first data link (146) and a first power transfer link (148) between a first serial port of a peripheral device (110) and the host computer. A second serial cable establishes a second data link (146) and a second power transfer link (148) between a second port of the peripheral device and an external power supply unit (PSU). A peripheral controller circuit (114) detects available power from the external PSU at a level suitable for use by the host device, notifies the host computer of the available power from the external PSU, and interconnects the first and second serial ports to flow the available power to the host device via the first and second power transfer links. The peripheral device may take the form of a solid-state drive (SSD) (110) with a non-volatile memory (118), such as flash memory.
