- NoFBoot is a small (256 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 6.x
- 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
- fast disk insertion/door closure. It will protect against accidents.
-
- Further, if any program is loaded AFTER NoFBoot that also can
- generate a reboot (such as McAfee's VShield) control is lost. NoFBoot
- (or SumFBoot) should always be loaded LAST.
-
- Either of these programs may be loaded "high" by either QEMM
- "Loadhi", Dos 5.0 or 6.x "Loadhigh". Other memory managers should
- also permit loading "high" but have not been tested.

- charge for their use however a copyright to the original code is
- retained by the author. Any distribution must include this file.
