PNP/PCI Configurations
These options configure how PnP (Plug and Play) and PCI expansion cards
operate in your system. Both the ISA and PCI buses on the Mainboard use
system IRQs (Interrupt ReQuests) and DMAs (Direct Memory Access). You must
set up the IRQ and DMA assignments correctly through the PnP/PCI
Configurations Setup utility for the mainboard to work properly. Selecting PnP/PCI
Configurations on the main program screen displays this menu:

PNP OS Installed (No)
Setting this option to Yes allows the PnP OS (instead of BIOS) to assign the
system resources such as IRQ and I/O address to the ISA PnP device. The
default setting is No.
Reset Configuration Data (Disabled)
If you enable this item and restart the system, any Plug and Play configuration
data stored in the BIOS setup is cleared from memory. New updated data is
created.
Resources Controlled By (Auto(ESCD))
You should leave this item at the default Auto (ESCD). Under this setting, the
system dynamically allocates resources to Plug and Play devices as they are
required. If you select the “Manual” option, the prompt on the following line,
“IRQ Resources” will become available to you.
You should leave this item at the default Auto (ESCD). Under this setting, the

If you cannot get a legacy ISA (Industry Standard Architecture) expansion card
to work properly, you might be able to solve the problem by changing this item
to Manual, and then opening up the IRQ Resources and Memory Resources
submenus.
