Making Newdos80 2.5 bootable

Apparat (the designers of Newdos80 and Newdos2.5) never thought the ROM would ever change to read a HDD so they didn't write a boot sector for the Model I. Well here is one from my Rence!
Without going into details too far the boot sector below tells the computer to go ahead reading from disk (in this case that is the hard disk). The computer should watch out for text (e.g. the name of a program), data and programs. Texts should be omitted. Data must be place a the right place (pdrive table etc.) and program commands should be run. Low format your hard disk and use Superzap (SCOPY command) to copy the boot sector at the right place on the hard disk.
