These options configure how PnP (Plug and Play) and PCI expansion cards operate in 
your system. Both the ISA and PCI buses on the motherboard 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 motherboard to work properly. Selecting PnP/PCI Configurations on the main 
program screen displays this menu:

 

 

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. 

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 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 submenu. 

In the IRQ Resources submenu, if you assign an IRQ to Legacy ISA, then that 
Interrupt Request Line is reserved for a legacy ISA expansion card. Press <Esc> to 
close the IRQ Resources submenu.
