BIOS Setup
Introduction
The purpose of this manual is to describe the settings in the Phoenix-Award™
BIOS Setup program on this motherboard. The Setup program allows users to
mod ify the bas ic s ystem co nfigur ation and save t hese settings to CMOS RAM.
The power of CMOS RAM is supplied by a battery so that it retains the Setup
info rmatio n when the po wer is turned off.
Basic Input-Output System (BIOS) determines what a computer can do without
accessing programs from a disk. This system controls most of the input and
outp ut devices suc h as keyboard, mous e, s erial po rts and disk drives . BIOS
activates at the first stage of the boo ting process, loading and executing the
operating system. Some additional features, such as virus and password
protectio n or c hipset fine-tuning options are also included in BIOS.
The rest of this manual will to guide you through the options and settings in
BIOS Setup.
Plug and Play Support
This PHOENIX-AWARD BIOS supports the Plug and Play Version 1.0A
specification and ESCD (Extended System Configuration Data) write.

7 PnP/PCI Configurations
This section describes configuring the PCI bus system. PCI, or Personal
Computer Interconnect, is a s ystem which allo ws I/O devic es to operat e at
speeds nearing the speed of the CPU itself us es when communicating with its
own special components. This section covers some very technical items and it is
strongly recommended that only experienc ed users should make any changes to
the default settings.

NF520-A2 TE/NF520-A2 SE/NF520-A 2
Reset Configuration Data
The s ystem BIOS s uppo rts the PnP feature which requires the system to record
whic h resourc es are assigned and protects resources from conflict.
Every per ipheral device has a node, whic h is called ESCD. This nod e records
whic h reso urc es a re as s igned to it. T he system needs to record and update ESCD
to the memor y loca tio ns. T hes e locations are reserved in the system BIOS. If the
Disabled (default) option is chosen, the system‘s ESCD will update only when
the ne w configuration varies fro m the last one. If the Enabled option is c hos e n,
the system is forced to update ESCDs and then is automatically set to t he
“Disabled” mode.
The above settings will be shown on the screen only if “Manual” is chosen for
the resourc es c ont ro lled by function.
Legac y is the term, whic h s ignifies that a reso urce is ass igned to the ISA Bus
and provides non-PnP ISA add-o n cards. PCI / ISA PnP signify that a resource
is assigned to the PCI Bus or provid es for ISA PnP add-on cards and
peripherals.
The Choices: Disabled (default), Enabled.
Resources Controlled By
By Choos ing “Auto(ESCD)” (default), the system BIOS will detect the system
resources and automatically assign the relative IRQ and DMA channel for each
perip heral. By Choosing “Manual”, the us er will need to ass ign IRQ & DMA for
add-on cards. Be sure that there are no IRQ/DMA and I/O port conflicts.
The Choices: Auto (ESCD) (default), Manual.
IRQ Resources
This sub menu will allow you to assign each syst em interrupt a type, d epending
on the type of device us ing the interrupt. When you press the “Press Ente r” tag,
you will be directed to a sub men u that wi ll allo w you to co nfigure the system
interrupts. T his is only configurable when “Resources Controlled By” is set to
“Manual”.
IRQ-5 ass igned to PCI Device
IRQ-7 ass igned to PCI Device
IRQ-9 ass igned to PCI Device
IRQ-10 ass igned to PCI Device
IRQ-11 ass igned to PCI Device
IRQ-14 ass igned to PCI Device
IRQ-15 ass igned to PCI Device
