Patent number: 11989551Abstract: Boot firmware for a computing device can be modularly and dynamically composed to facilitate implementing changes and updates to a computing device's firmware. The firmware image can include a primary module, which is responsible for certain basic initializations, and a module list, which can include a listing of additional modules that are to be executed during the boot procedure. The module list can be used to identify and access the selected modules from a module library, such as via globally unique identifiers (GUIDs). Once acquired, the selected modules can be executed, taking into account required dependency modules (whether included in the selected modules or not) and configuration settings. The module library can be stored entirely locally (e.g., as part of a distributed firmware image), entirely remotely (e.g., accessible via network connection), or a mixture of locally and remotely.Type: GrantFiled: March 18, 2021Date of Patent: May 21, 2024Assignee: QUANTA COMPUTER INC.Inventors: Cheng-Han Chen, Yi-Chun Liao, Kuo-Chun Liao, Chong-Ren Guo

Patent number: 10977158Abstract: Firmware can be built to be capable of generating and outputting trace data, during execution, to assist in debugging firmware problems without substantially slowing operation of the firmware and without potentially disclosing secret information associated with the firmware. The firmware (e.g., BIOS) can output hash digests of various modules within the firmware, which can be compared with a pre-established mapping table to identify modules that successfully completed or did not successfully complete during execution of the firmware, such as during a startup procedure. The hash digest can be a one-way hash, which can be rapidly executable during operation of the firmware and can keep the code of the modules hidden from unauthorized reverse engineering.Type: GrantFiled: March 27, 2020Date of Patent: April 13, 2021Assignee: QUANTA COMPUTER INC.Inventors: Cheng-Han Chen, Cheng-Han Wu, Jyun-Jie Huang
