If this option is enabled, an alarm message will be displayed when trying to write

CPU Internal Cache
Cache memory is additional memory that is much faster than conventional
DRAM (system memory). CPUs from 486-type on up contain internal cache
memory, and most, but not all, modern PCs have additional (external) cache
memory. When the CPU requests data, the system transfers the requested data
from the main DRAM into cache memory, for even faster access by the CPU.
First/Second/Third Boot Device
These fields determine the drive that the system searches first for an
operating system. The options available include LS120, HDD-0, SCSI,
CDROM, HDD-1, USB-FDD, USB-ZIP, LAN, USB-CDROM,
USB-HDD and Disabled.
Boot Other Device
These fields allow the system to search for an OS from other devices
other than the ones selected in the First/Second/Third Boot Device.
