Abstract

Securely removing system capabilities, being available to at least one logical partition, from that partition, the partition being hosted by a computer system running an operating system. The system capabilities are available to a boot loader of the computer system, wherein the boot loader is started in the logical partition. The logical partition remains activated while removing the system capabilities. A removal request is initiated by the boot loader; and a deconfigure command is performed by the boot loader.
