If it is a desktop, it is very easy to reset the BIOS. Either find the jumper to reset the BIOS, or remove the system battery (watch battery usually CR2032 or CR2012). Leave the battery out for about 10 minutes (with the machine unplugged, of course) and re-install it and reconfigure your BIOS.
If it is a laptop, it may not have a CMOS battery, or it may store the password on non volatile memory (which means loss of power will not erase it). In this case you should have your IT staff contact the Manufacturer for the Master BIOS password (which may or may not exist). If the OE does not have the reset password you will have to send the unit back to them so they can replace the BIOS chip.
