PnP/PCI Configuration 5DHX
PnP/PCI Configuration
The System BIOS on a PCI platform plays the role of a System Resources
Manager. Its main job is to dynamically allocate system resources such as I/O,
Memory & IRQs to all PCI devices without any conflicts!

Resources Controlled By
You can allocate the system resources manually by choosing manual. If choose
AUTO in this option, the system resources will be allowcated automatically.
Reset Configuration Data
Select enabled in this option if you want to reset your PnP hardware information
which stored in the system board. For normal use, this option should be set to
disabled.
IRQ-3 to 15, DMA-0 to 7
If you select manual in the Resources Controlled by option, you need to assign the
system resources manually. In the resources list, you can assign the resources
either for PCI / ISA PnP or for legacy (non-PnP) ISA. If you are using a legacy
ISA card and using a specified IRQ or DMA, you should assign your system
resources correctly for that ISA card otherwise you system / peripheral card will
not function correctly.
