Pnp/Pci Configuration Option - ECS P5SD-B Plus Manual

PNP/PCI Configuration Option

This option displays a table of items that configures how PNP (Plug and Play) and PCI
expansion cards operate in your system. If you have not installed a riser card with
expansion slots, you do not need to make any changes to this option.
PNP OS Installed
If you have installed a Plug and Play operating system such as Windows 95 or 98, you can
change this item to Yes. When the item is set to Yes you can use the Device Manager
utility in the operating system to make changes to the configuration of expansion cards.
Resources Controlled By
You should leave this item at the default Auto. If you find that you cannot get a particular
expansion card to work properly, you might be able to solve the problem by changing this
item to Manual, and defining the characteristics of the card in the new items which appear.
If you change this item to Manual, the display will list a series of items that allow you to
define the assignments of the system interrupt lines (IRQs) and Direct Memory Access
(DMA) channels. As a default, these items are set to PCI/ISA PnP. If you install an ISA-
bus card that does not support PNP, and it requires a special IRQ and DMA, you can
modify the list of assignments. Change the values of the IRQ and DMA that are required to
Legacy ISA.
Reset Configuration Data
If you enable this item and restart the system, any PNP configuration data stored in the
BIOS setup will be cleared from memory. New updated configuration data will be created.
ACPI I/O Device Mode
This item is used for system development and diagnostics. Leave this item at the default
value Enabled.
Assign IRQ for USB
When this item is enabled, the system will assign an IRQ to the USB ports.
