Abstract

A computer-implemented method, for booting a computer system, that provides a list with entries of startup processes. Each startup process defines a resource of the computer system. For each startup process a requirement is defined. The method further comprises fetching one of the entries of the list with entries of startup processes; determining whether the requirement is satisfied for the one of the entries of the list with entries of startup processes; fetching, in case the requirement is not fulfilled, a next one of the entries of the list with entries of startup processes; starting, in case the required resource is fulfilled, the startup process; and repeating the fetching a next one of the entries, the determining and the starting until all startup processes of the list of startup processes have been started.

Claims9

Dependent claims

A computer-implemented method for booting a computer system, comprising:

producing an extended boot sequence table (BST-E) with respect to a plurality of startup processes, where for each startup process, the BST-E includes a computer system resource requirement;
determining, with respect to each startup process, whether a corresponding computer system resource requirement is satisfied;
for each startup process of the plurality of startup processes, on condition a corresponding system resource requirement is satisfied, starting the startup process;
for each startup process, on condition the corresponding system resource requirement is not satisfied, placing the startup process in a wait status;
receive a trigger indicative of a resource becoming available, the resource satisfying a computer system resource requirement for a corresponding startup process that is in the wait status;
and
remove the wait status from the corresponding startup process.
