- TITLE : Deleting the Password in PARADOX.SOM
-
-
-
-
- The network installation program for Paradox2 requires you to
- enter a password, which you must know if you later use NUPDATE to
- change your configuration. In an emergency, a user can bypass
- this protection scheme by using DEBUG to erase the existing
- password. To do this, just change the byte at addres 18e to
- binary zeroes. (The password is an eight-byte null-terminated
- string, so zeroing out one byte does the job.)
-
- For users who are not conversant with DEBUG, here are more
- detailed instructions:
-
- 1. In the directory containing Paradox2 on the network, type
- DEBUG PARADOX.SOM to enter the DEBUG program.
-
- 2. At the hyphen, which is DEBUG's prompt, type: d 180 and
- press <ENTER>. This should display eight lines of 16
- characters each, in both hexadecimal and ASCII format.
- The first line will be labeled "xxxx:0180", where "xxxx"
- is any value. The character we want to change is the next
- to last one in the first line.
-
- 3. At the hyphen prompt, type: e 18e and press <ENTER>.
- (Note that "180" and "18e" sound alike. It is essential
- that you edit byte 18e, not 180!.) DEBUG will display the
- address to be edited, the current value and a period, then
- wait for you to supply a new value.
-
- 4. Type: 00 (two zeroes) and press <ENTER>. (The zeroes are
- hexadecimal characters; together, they represent one ASCII
- character - to be specific, a null character, to tell
- Paradox that there's no password.
-
- 5. Check that the change was made correctly by repeating step
- 2. The changed character will now appear as "00". If
- something has gone wrong, type: q at the prompt to cancel
- the change, then start again with step 1.
-
- 6. If everything looks okay, type: w at the prompt to write
- the modified version of PARADOX2.SOM to disk, then (at the
- next prompt), type: q to exit DEBUG.
