Note If the destination computer’s HAL is compatible, but not identical, to the source computer’s HAL, you must update the HAL on the destination computer after you finish the restore. For example, if the source computer has a single processor and is using the ACPI uniprocessor HAL, you can restore a backup from that computer to a multiprocessor destination computer. However, the destination computer will not use more than one processor until you update the HAL to an ACPI multiprocessor HAL.
To determine the computer HAL type that you are using on each computer, follow these steps: 1. Click Start, point to Settings, click Control Panel, and then click System.
2. On the Hardware tab, click Device Manager, and then expand the Computer branch.
