I have a machine for wire cutting. It must boot from its own processing card, and cannot boot from a floppy disk or hard disk, otherwise it cannot carry out wire-cutting tasks. After it boots, is there any way to then enter the hard disk and execute some command to connect it to the LAN, instead of entering the network by booting from a floppy disk or hard disk? Its built-in processing card cannot be modified. I hope all the experts here can give me some advice...
