- NoFBoot
- Copyright 1991 by Padgett
-
- NoFBoot is a small (368 byte) TSR designed to prevent
- inadvertant booting from a floppy disk. It will intercept warm boot
- requests (Ctrl-Alt-Del) and check for a floppy in drive A before
- continuing. If a floppy is found in drive A, the request will be
- aborted with a warning message. With NoFBoot, a cold start (reset
- button or cycle power) will be necessary to boot from a floppy.
-
- SumFBoot is an alternative to NoFBoot that may also be used. It
- allows a floppy boot when Ctrl-Alt-F is pressed. In this case if a
- floppy is NOT present the boot will be aborted.
-
- Use of either of these program is designed to give the user
- control of the resetting of a PC and to protect against "accidents".
-
- The programs will run under versions of MS-DOS from 2.10 to 5.00
- and are designed to be transparent to the user unless a warm boot is
- requested from a floppy. In that case a warning message will appear.
-
- In most cases, denial of a warm boot should have no effect on a
- running program.
-
- It must be remembered that once the boot process starts, all
- control is lost and NoFBoot cannot override a BIOS decision or †a ç
- fast †disk insertion/door closure. It†will protect against accidents,
- not deliberate attempts.
-
- Additionally, any program that issues a direct BIOS call to the
- reboot function will bypass NoFBoot as will any subsequent TSR (e.g.
- McAfee Associates VSHIELD) that trap the warm boot function.
-
- If such other TSRs exist, for NoFBoot to be effective, it must
- be loaded LAST.
-
- These programs are presented as FREEWARE, e.g. there is no
- charge for their use however a copyright to the original code is
- retained by the author, no changes to the code are permitted without
- permission, and distribution must include this document.
-
- Disclaimer: These programs are presented AS IS and no guarantee
- for fitness of any kind is made or implied. All use is at the sole
- discretion of the user. I have tested these programs as extensively
- as possible with limited resources but have not seen all possible
- combinations of hardware and software. Caveat y'all.
