THE PURPOSE:
=============
Keep the Bozos Out is an INIT/Extension that offers simple password protection for your Macintosh's hard drives. If you don't know the password at startup, you can't access your hard drive. The operative word with this software is "Bozo". While certain Macintosh power users and hackers can circumvent KtBO, the average Bozo that just wants to fool around with your machine in your absence is out of luck.
THE INSTALLATION:
==================
Drag KtBO INIT to the System Folder on the main level of your hard drive. System 7 users will be asked if they want KtBO put in the Extensions folder. (Yes, they do) Put BozoEdit wherever you keep utility applications on your hard drive. NOTE: BozoEdit must be stored on the same hard drive as the System Folder containing KtBO.
THE SETUP:
==========
Launch BozoEdit. When asked for the password, type in "bozo". (Without the quotes) You will now be prompted with a dialog box. At the top, you will see an edit field with the password "bozo" in it. You can change this to any password you wish. KtBO passwords are case sensitive, i.e., "bozo", "Bozo", and "BOZO" are all considered different passwords. Click the done button and confirm changes to set your new password. Restarting the Mac at this point will load KtBO and it's protection code.
NOW WHAT?
===========
When you do a Shut Down on your Mac (after restarting with KtBO installed), KtBO protects your attached hard drives by making the contents inaccessible. The only way to regain access is to boot the machine and enter the correct password when KtBO's dialog box comes up. Users bypassing Extensions with the shift key at startup (System 7 only) or booting with a floppy will not have access.
This is about the extent of instructions most users will need with KtBO. (Pretty simple, huh?) If you leave your Mac running while you're away from your desk at any time, I recommend using a screen saver with password protection. KtBO is only effective AFTER you have shut down your machine.
KEEP THE BOZOS OUT IS POSTCARDWARE!!!
Instead of creating a "shareware" utility and charging a fee for it, I decided to release KtBO as "postcardware". If you use it, please send me a postcard. I don't think it's a whole lot to ask for what I think is a pretty useful INIT that is basically free.
QUESTIONS AND ANSWERS:
========================
Q: What are the other functions I see available in BozoEdit?
A: Read the rest of these questions. If none of the questions apply to you, you don't need the other functions of BozoEdit. Of course, you can still read them if you're curious.
Q: I moved to an office with a door I can lock. I no longer need KtBO to keep the bozos at my company off of my machine. How do I remove KtBO safely?
A: You can't. Okay, okay, relax -- you can. To safely remove KtBO, move it from your System/Extensions folder to any other folder (or trash). Then do a Restart.
After removing KtBO from your system, you MUST do a Restart on your Mac. KtBO is still installed UNTIL you restart your machine. If you accidentally do a Shut Down after removing KtBO, your hard drive will be protected. Next time you boot up your machine, KtBO won't be around to deprotect your drive, and your system folder won't be available for you to re-install it!
Q: I just restarted my Mac after having Shut Down for the first time with KtBO installed. I see files on the main level of my hard drive that I've never seen before. What's with that?
A: Here's where one of those other functions of BozoEdit come in. Certain other utilities create invisible files on the main level of your hard drive. (Disk Express and Norton Utilities are good examples) Select the name of the new file and do a Command-C, or Copy from the Edit menu. (If there's more than one new file, just pick one to start with. You need to do them one at a time) Launch BozoEdit. Go to the FIRST EMPTY field in the section marked "Files/Folders to keep invisible" and click in it to put the insertion bar there. Do a Command-V, or Paste from the Edit menu. The name of the file will be placed in the field. Repeat this for any additional file names. (MultiFinder and System 7 users can switch easily between the Finder and BozoEdit without having to quit BozoEdit) Click on the done button and confirm changes. Next time you start your machine up, these files will no longer be visible. NOTE: Be certain not to leave empty fields in the middle of this list. KtBO will skip anything you've entered beyond an empty field. For example, if you have three names in your keep invisible list and erase the second, only the first name will be seen by KtBO on the next boot. In this case, the name in the third field must be deleted and re-entered in the second.
Q: I had a syquest cartridge mounted when I Shut Down my Macintosh. Using my machine today, I re-mounted the cartridge and found that the contents of the cartridge were missing! What do I do?
A: This can occur with any volume on the SCSI bus that can be mounted and unmounted at will. (This includes cartridges and secondary hard drive partitions) KtBO protected your cartridge at shutdown time, but the cartridge wasn't on-line at startup for KtBO to deprotect it. Your solution is to mount the cartridge, launch BozoEdit, and select "Unprotect Mounted Drives" from the File menu. This will restore your cartridge.
Q: Now that my cartridge's contents are back and my pulse is normal, how can I keep this from happening again?!
A: Easy. Don't do a Shut Down without unmounting the cartridge first. Okay, seriously... You can either create a folder or any document on the main level of the cartridge. Make sure the file/folder name is "Don't Protect This Volume". (Don't use the quotes and make sure to use the same capitalization and punctuation) KtBO will now skip this volume at Shut Down. The next time you do a Shut Down with this volume still mounted, KtBO will make this file/folder disappear, but the volume will not be protected anymore.
Q: Can I rename the KtBO INIT?
A: Yes, but don't. It will change how KtBO loads at startup, and BozoEdit will not be able to access it to make changes. Also, don't lock the KtBO INIT file.
Q: Are there any compatibility issues with KtBO?
A: None that I have come across.
Q: Will KtBO affect any floppy disks in drives at shutdown time?
A: No.
Q: I have a question about KtBO that isn't answered here. Is there any way to contact you electronically? I can't stand regular mail.
A: Me, no. But you can send your question (or bug report!) to Mike Domoy on America Online or just about any Mac-oriented FidoNet Echo for a prompt answer. He's as intimately aware of KtBO's inner workings as I am. We also welcome any comments you'd like to submit.
Don't forget to send your postcard!
UPDATE INFO
============
Version 1.1:
Apparently Macintosh Classics running System 6.0.x don't like it when KtBO closes the dialog window after deprotecting a hard drive. I've included exception code that keeps the window open while INITs load. This is the only configuration that I know of that causes a crash with KtBO. If anyone knows otherwise, PLEASE LET ME KNOW! (Likewise, if anyone out there can clue me in to what might cause this, ditto! The fix isn't elegant, and I'd like to get rid of it.)
KtBO no longer causes Stuffit SpaceSaver to decompress files at Shutdown. (A really annoying problem, to say the least. Especially when there's not enough room on your hard drive for the decompressed files!)
Version 1.2:
The same bug that caused problems with Classics in version1.0 turned out to affect >any< 68000 powered Macintosh running system 6.0.x. This has been fixed.
BozoEdit 1.1:
The Return and Enter keys did not dismiss the main dialog box in version 1.0. Instead, the Enter key would produce a box in the current edit field while a Return would cause any text behind the insertion bar to disapear. That text would scroll "up" in the edit field, while the rest would stay on the lower, visible section of the edit field. It was easy to enter text into and empty field, namely the password field, hit Return, (expecting the dialog to close) see the text disapear, and re-type text into what appeared to be an empty field. Clicking on the "Done" and "OK" boxes would then save the password along with the Return character and previously entered password as one password. Even if a user realized what they did, they couldn't type the Return character as part of the password at boot time. (Since the Return key does what you expect it to at that point!) These keys do what most Macintosh users expect to see in this version.
