Reset Configuration Data:
Select Enabled to reset Extended System Configuration Data (ESCD) when you exit
Setup if you have installed a new add-on and the system reconfiguration has caused
such a serious conflict that the OS cannot boot.
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 CPU to 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].
