- Making a Boot Disk
-
- You should make sure that you always have a boot floppy available
- for your system. There are things that can go wrong which may make
- it impossible to boot from your hard disk. Many of these are
- simple problems which can easily be fixed, but only if you can
- start up the computer.
-
- Even if you don't consider yourself a power user, you can make sure
- that you can boot from a floppy. With a boot floppy, you may be
- able to restore the computer yourself. You may know exactly what
- went wrong and how to fix it.
-
- For more difficult problems, you may be able to get help from a
- service department or technical support by telephone. If you can
- describe the symptom and can access your hard disk, someone may be
- able to walk you through the steps necessary to restore operations.
- This can save you hours or days of unnecessary downtime.
-
- If you have the original diskettes that came with your system, you
- can use the system disk as a boot floppy. A better idea would be to
- make copies of them, and keep the originals safe. With these you
- have a complete operating system, but you will not have any custom
- features you may have installed yourself.
-
- If you do not have your original system disks, you can make a boot
- floppy. You will need to use the DOS format command with the
- system option. The statement:
-
- FORMAT A: /S
-
- will format and transfer the operating system programs to a
- diskette in your A drive. This would be a minimum boot floppy. You
- should also copy other DOS programs to this floppy. If you can,
- copy all the DOS programs. If you do not have room, copy at least
- EDLIN.COM and DEBUG.COM. You can use EDLIN to edit files. You may
- be guided in the use of DEBUG by others. Other programs of more
- general use are MODE.COM, CHKDSK.COM, and FORMAT.COM. Include these
- also.
-
- You can also copy your CONFIG.SYS and AUTOEXEC.BAT files to this
- floppy. However, they will probably not work well without some
- additional effort. This effort involves editing the files, copying
- other program files to the floppy, or both. Since these files
- represent custom features, the changes you might need to make
- cannot be covered here.
-
- Finally, assuming you have a boot floppy now, you should try it
- out. Make sure you can boot from a floppy disk. See what features
- and capabilities you have under these circumstances. Observe what
- features you will have to do without if necessary.
