【正确答案】 A

【答案解析】解析：Explanation: The hardware abstraction layer (HAL) is installed during the installation of the operating system. Usually the operating system will detect the HAL and install a standard HAL. To install the customized hardware abstraction layer (HAL) designed for the computer that the manufacturer has provided we must press F6 when the Windows 2000 setup prompts us to do so. This will allow us to supply the setup program with the customized HAL that should be installed. To supply a HAL file to Setup, we should press F5 and specify the type of custom Hardware Abstraction Layer (HAL) to be loaded by the Setup Loader and installed by text-mode Setup. Incorrect answers: B: The Recovery Console is not used to install the HAL. C: The Emergency Repair process is not used to install the HAL. D: Device manager could be used to upgrade the HAL for multiprocessor support. However, the HAL is configured during the Windows 2000 installation phase.
