A target device initiates the boot process by first loading a bootstrap program. A bootstrap program is a small program that runs before the operating system is loaded. Provisioning Services uses a special bootstrap program that initializes the streaming session between the target device and the Provisioning Server. After this session starts, the operating system begins to be streamed and loaded from the vDisk that was initiated.
The PXE service can deliver the bootstrap file location to a target device according to the PXE Specification Version 2.1. Use this service if a DHCP service exists and cannot be changed, and another PXE service is not used.
The TFTP service delivers the bootstrap file to a target device on request. Use it if another TFTP service is not available.
The illustrations and steps that follow describe the boot process both with and without the use of PXE.
