Boot Sector Virus Protection [Disabled]
This field allows you to set boot virus detection, ensuring a virus-free boot sector.
The system halts and displays a warning message when it detects a virus. If this
occurs, you can either allow the operation to continue or use a virus-free bootable
floppy disk to restart and investigate your system. Yet because of conflicts with new
operating systems, for example, during installation of new software, the default is
set to [Disabled] to prevent write errors.
