Note
Scanning for Option ROMs on devices behind a PCI bridge cannot be disabled.

device
x
will be scanned for an option ROM. Setting this option to
Enabled
allows the BIOS to scan for a PCI option ROM on this PCI device. Setting
to
Disabled
prevents the BIOS from detecting option ROMs on this device.
Setting to
Disabled
does not completely disable the PCI device, just the
option ROM scan. The default is
Enabled
.

Write Protect Boot Sector

modification of a hard disk boot sector via INT 13h services, which may

system drivers that access the hard disk directly. The default is
No
.

controller. The BIOS proceeds down the
Boot priority order list
