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 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:
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.
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 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.
