PNP/PCI Configurations
This section describes configuring the PCI bus system. PCI (Peripheral Com-
ponent Interconnect) is a system, which allows I/O devices to operate at
speeds nearing CPU’s when they communicate with own special components.
All the options describes in this section are important and technical and it is
strongly recommended that only experienced users should make any changes
to the default settings.

PNP OS Installed (No)
Setting this option to Yes allows the PnP OS (instead of BIOS) to assign the
system resources such as IRQ and I/O address to the ISA PnP device. The
default setting is No.
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. New updated data is
created.
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 and Memory Resources
sub-menus.
In the IRQ Resources sub-menu, if you change any of the IRQ assignations to
Legacy ISA, then that Interrupt Request Line is reserved for a legacy ISA ex-
pansion card. Press <Esc> to close the IRQ Resources sub-menu.
In the Memory Resources sub menu, use the first item Reserved Memory
Base to set the start address of the memory you want to reserve for the ISA
