Reset Configuration Data
If you want to reset CMOS IRQ divide hardware device, please selected to [Enabled].
Resources Controlled By
When set to Manual the system BIOS will not refer to the ESCD for IRQ & DMA
information. Instead, it will refer to the items in the setup menu for assigning IRQ &
DMA. When set to Auto the system BIOS will refer to the ESCD for all legacy
information. ESCD (Extended System Configuration Data) provides a detailed format of
the configuration data structures stored in flash memory. Each data structure defines the
resources used by a device or a card in the system. This includes legacy and PCI/ISA PnP
devices.
PCI/VGA Palette Snoop
When set to [Enabled], multiple VGA devices operating on different buses can handle
data from the CPU on each set of palette registers on every video device. Bit 5 of the
command register in the PCI device configuration space is the VGA Palette Snoop bit (0
is disabled). Available options are [Enabled] and [Disabled].
FDD IRQ Can Be Free
This function allows user to choose if the FDD IRQ can be freed up. The default setting
is [Yes] and this does not allow the IRQ to be free.
