Abstract
Apparatus and methods for replacing partition units are disclosed. Generic and platform-specific drivers based on a driver model that specify a plurality of callbacks are disclosed. The drivers enable the replacement of partition units without the firmware and/or software of a computing device having to be recompiled for each platform. The plurality of callbacks provide access to a plurality of functions that are safe to use when operating system services are not available. The plurality of callbacks include, but are not limited to, initialization, memory transfer, and transfer processor state callbacks. The methods use the drivers to replace partition units. Preferably, partition units are replaced using platform-specific partition unit replacement (PUR) drivers that take advantage of platform-specific capabilities.
