Summary:Provided are a computer program product, system, and method for verification of a boot loader program at a control unit to be provided to a host system to load an operating system. A stored value is generated from a cryptographic function applied to portions of a boot loader program stored in the storage. The boot loader program is read from the storage in response to execution of a boot loader request from the host system. The cryptographic function is applied to at least a portion of the read boot loader program to produce a calculated value. The host system is provided access to the boot loader program to use to load the operating system from the storage into the host system in response to the calculated value matching the stored value.
