Abstract
In one embodiment, a multiprocessor computer system comprises at least a first partition having a first operating system and a second partition having a second operating system, comprising logic in the first operating system to generate a request to remove a device from the first partition, logic in a firmware module in the computer system to invoke an ACPI interface eject method for the device in response to the request to remove the device, determine whether the device has memory spaced allocated to it by firmware in the computer system, and reject the ACPI interface eject method when the device has memory spaced allocated to it by firmware in the computer system.
