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. 54 ASUS K7M-RM User’s Manual
