>University of Houston can disable boot up from drive A:
That is very simple, if you have only one floppy. Open your computer
and set DIP switches and cable connections to make A: as B:. After
that insert in AUTOEXEC.BAT a program which overrides all requests
from A: to B: to avoid problems with an addressing. If you have more
than one floppy, make them E:, F: etc. if you have an additional
floppy interfaces.

Older BIOS versions will bump if they don't find a disk-drive. Some BIOS versions will boot from drive B: Best solution I have found is to disconnect the disk-drives (pull the data-connector out of the disk-drive) or modify the CMOS. Both methods are incompatible with some BIOS versions, so be arware! A may-be solution is to use an encreption method on the hard-disk for which the user has to us a password, or modify your BIOS to disable floppy-disk booting. These methods are very tricky and only suitable for people that know what they are doing. >(about difference between writing virusses for Mac or PC) >magnatude less than producing a good word processor.

In the PC that is rather difficult. It is possible if you dig into DOS very deep. This would be incompatible for many DOS versions. It is a very good idea however, but the PC doesn't give a signal when a new disk inserted. Only a changeline-signale if the drive door has been opened. I'll pass this suggestion over to the author of TBSCAN. - ------------------------------------------------------------------------ From: James Ford <JFORD@UA1VM.BITNET> >The file "innoc.zip" has been replaced with a new version.
