Figure 3-7 PNP/PCI Configurations
PNP OS Installed:
If you want to install a PNP compatible OS ( such as Windows 95 ) set to Yes.
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
].
