Abstract
A method, system and computer program product for managing multiple software images in a data processing entity. At least part of the memory blocks of each of the software images is stored into a corresponding image portion of a mass memory. A current software image stored in a current image is selected. The memory blocks stored in boot locations of the current software image are relocated to a relocation portion of the mass memory. The boot blocks of the current software image are copied into the corresponding boot location. The data processing entity is booted from the boot blocks of the current software image in the corresponding boot locations and each request to access a selected memory block of the current software image by the access function is served.
