TRS-80 Software REGISTRATION NUMBER 00000001 NEWDOS 8O FOR THE TRS-80 MODEL I / III / 4 MICRO COMPUTER Apparat Incorporated takes pleasure in presenting NEWDOS/80, Version 2.5. Above is the registration number of your NEWDOS/80. This registration number must be the same as the registration number you find on your diskette label and the enclosed registration card. If they are not, return them to the dealer from whom you purchased your NEWDOS/80 to be reissued. This registration Number is your assurance of receiving any corrections or minor revisions to NEWDOS/80 that may be released. The registration card should be completed and returned to Apparat at your earliest convenience. PLEASE RETURN THE CARD IT IS IMPORTANT! It our only method of determining who has purchased this copy of the system. This number should be included in all correspondence with Apparat. Apparat, Inc 4401 So. Tamarac Parkway • Denver, Colorado 80237 HELPFUL HINTS IN USING YOUR NEWDOS/80 VERSION 2.5 We suggest using the following checklist as a guide to setting up software on your Hard Disk System: 1. Carefully read through all related documentation. 2. Make hardware installation as directed by instructions supplied with your Hard Drive Unit. 3. Boot on your NEWDOS/80 Version 2.5 original master diskette and make backup copy or copies. Refer to Chapter 1, Section 1.4 of the NEWDOS/80 Version 2.0 manual for details if unfamiliar with the procedure. 4. Designate one of your backups as a working copy an d boot (or reset) on it. Use this diskette for the remainder of this procedure. 5. Use HDFMTAPP/CMD. Refer to Section 4 in the NEWDOS/80 Version 2.5 manual (Appendix C). 6. Set up your PDRIVE definitions for the Hard Drive Volumes according to Section 3 & 6 of the NEWDOS/80 Version 2.5 manual. 7. Use DOS command FORMAT on each defined volume of the Hard Disk. This has not been very clear to some of our users. HDFMTAPP/CMD is only a "media format" utility that allows the hard drive to be used with NEWDOS/80 (or other DOS system). DOS command FORMAT, although does not prepare the media as HDFMTAPP/CMD, is important for checking the media and preparing the directory (DIR/SYS) and the boot sectors (BOOT/SYS) on the hard drive volumes. If the volume was not prepared with FORMAT, it will seem to operate correctly with COPY, OPEN, and CLOSE (ie. normal file operations), but HDBACKUP/CMD and DIRCHECK/CMD will not function. 8. (Optional) Move NEWDOS/80 Version 2.5 to Hard Disk Volume. Refer to Section 5 of the NEWDOS/80 Version 2.5 manual. Don't forget to move your PDRIVE definitions to appropriate new slots. Follow procedure to create Boot Diskette. 9. Install application software and related data files. Table of Contents Chapter 1. INTRODUCTION 1.1.
