Booting the ZY

As described in appendix A, the ZY computers boot from a local 1.44 MByte floppy. DOS and the network software reside on this floppy, as well as a simple FTP client program, RLOAD.EXE, whose sole purpose is to retrieve the ZY executable. After RLOAD.EXE successfully terminates, ZY.EXE is executed, and initializes itself. Booting thus involves ensuring that the proper hardware is installed, inserting a boot diskette that was created according to the instructions in appendix A, and turning on the power. At the end of the boot process, the ZY is ready to be used.
