ABSTRACT:
A mechanism for uninterrupted booting of a client computer coupled to a pre-boot execution server computer over a network is provided. The client computer has at least two or more network interface cards. A network bootstrap file is downloaded from the server computer to the client computer. The network bootstrap file is configured to monitor the booting process of the client computer. On detection that the network interface card has failed to transmit or receive packets, the network bootstrap file is configured to switch over to the next available network interface card on the client system thereby providing uninterrupted execution of the booting process.
