Fortres?

I work for a school that has recently installed Fortres Security Interface. I have a problem with students booting to floppies and manipulating the autoexec.bat file to not load the Fortres program. I can not get into my BIOS to change the boot sequence. My BIOS password has been previously set. I looked for a jumper to remove BIOS password to no avail. Then, I tried removing the battery overnight. This also did not work. What can I do? Any help will be greatly appreciated. Thank you.
