Description
PNP OS Installed Yes No Yes, No If the operating system (OS) is Plug and Play (for example
Windows 95), select “
Yes ” if you want the OS to allocate
resources according to Plug and Play standards, or “ No ” if you
want the same resource allocations at every system boot-up.
Select “
No ” when the OS is not Plug and Play (for example,
DOS).
Note: When set to “Yes”, only the boot devices will get
Resources.
Resources Controlled
By Auto Man. Auto, Man. The Award Plug and Play BIOS can automatically configure all the
boot and Plug and Play-compatible devices. If you select Auto, all
the interrupt requests (IRQs) and DMA assignment fields
disappear as well as Used Mem Base Address and Lenght as the
BIOS automatically assigns them.
Reset Configuration
Data Dis. Dis. En./Dis. Normally, you leave this field Disabled. Select Enabled to reset
Extended System Configuration Data (ESCD) when you exit
Setup if you have installed a new add-on and the system

When resources are controlled manually, assign each system
interrupt as one of the following types, depending on the type of
device using the interrupt:
Legacy ISA: Devices compliant with the original PC AT bus
specification, requiring a specific interrupt.
PCI/ISA PnP: Devices compliant with the Plug and Play standard,
whether designed for PCI or ISA bus architecture.
When Legacy ISA is selected for an IRQ line, this resource will not
be available for PCI/ISA PnP.
