- Here are two memory resident utilities to protect yourself from being
- Trojaned from Hackers. These two files have been in full use on both
- InfoLink Network and LaserNET PCBoards. Please feel free to pass these
- two files along with this document to other BBS operators. Thanks,
- Tim Conner (Sysop, InfoLink/LaserNET Systems).

- WPHD.COM - Run this to write- and format-protect your hard disk. Useful
- when letting someone else use your PC or when trying out
- new BBS software. Each time it is run it
- toggles the protection off or on - no need to reboot to get
- rid of it. The toggle ON/OFF feature will not work if, after
- running WPHD, you run another RESIDENT program that
- re-vectors INT 13. In other words, run WPHD after running
- other resident programs, such as Sidekick.
- If the DOS FORMAT command is run when this is on, it will
- appear to be formatting your hard disk, but what it is
- actually doing is VERIFYing each sector, which does not
- harm the disk. Your data is actually lost during a format
- when DOS writes a new Directory and FAT - WPHD will prevent
- that. Actually, if WPHD is not installed and you accidentally
- start formatting your hard disk, you can type Ctrl-Break
- to stop the formatting. The Ctrl-Break will not be
- acknowledged right away, but that's ok - it will still break
- you out of format before any damage is done.
-
-
- FPHD.COM - This program will protect your hard disk against an
- accidental FORMAT, but will still allow writing to the
- disk. It is toggled on and off in the same way that WPHD is.
- The line FPHD should be put in your AUTOEXEC.BAT file.
- Remember though that if someone reboots your system from
- the "A" drive, this protection will be gone. But see the
- discussion above; if you hit Ctrl-Break before the very end of
- the formatting, you will save your hard disk.
-
- ** NOTE ** To All users of DoubleDOS, Please set these two files within
- your AUTOEXEC.BAT file prior to loading PCBoard!
