    摘要: Methods and apparatus to enable console redirection in a multiple execution environment are disclosed. In an example method, at least one periodic interrupt in a first basic input/output system (BIOS) execution environment of a local console is initiated. Data associated with a second BIOS execution environment of the local console is retrieved. The data associated with the second BIOS execution environment is communicated to a remote terminal.

    摘要: Redirection of accesses to non-existent memory is instead sent to a virtual buffer. The virtual buffer may be implemented in headless systems which include no video buffer. Console redirection may use the virtual buffer to display information about the headless system. Accesses to the non-existent video hardware, either directly or using the BIOS API, are redirected to the virtual buffer before being retrieved by a remote console. The headless system is cheaper and may support additional add-in cards because the system includes no video controller.

    摘要: Technologies for secure offline activation of hardware features include a target computing device having a platform controller hub (PCH) including a converged security and manageability engine (CSME) and a number of in-field programmable fuses (IFPs). During assembly of the target computing device by an original equipment manufacturer (OEM), the CSME is provided a list of hardware features to be activated. The CSME configures the IFPs to enable the requested features, generates a digital receipt including the activated features and a unique device ID, and signs the receipt using a unique device key. Signed receipts may be periodically submitted to a vendor computing device, which verifies the signed receipts, extracts the active feature list, and bills the OEM for activated features of the PCHs. The vendor computing device may bill the OEM a maximum price for PCHs for which there is no associated signed receipt. Other embodiments are described and claimed.
