The invention relates to a pre-launch execution environment testing device, method and system.

The Pre-boot Execute Environment (PXE) is a technology that enables a computer to download a mapping file from a remote server over a network and thereby support the boot process of the operating system from the network. At present, various server boards have the function of PXE startup, and the testing requirements for this function are also increasing. During the test, the PXE server needs to be configured to store modules such as Dynamic Host Configuration Protocol (DHCP), Trivial File Transfer Protocol (TFTP), and Test Image (map file). The client computer connects to the server through a network card with PXE boot function, downloads the mapping file and starts the operating system.

However, this test method has obvious disadvantages. For example, when multiple client computers are connected to the server for testing, if the server has an abnormality such as a crash, power failure, or virus, or if there is a problem with the network, all the client computers will be affected, so The stability requirements of the server are very high; if only one client computer needs to be tested, the server must work at the same time, and the cost cannot be reduced.
