Overview
The NT928 P2BXD is a Pentium II based mainboard that utilizes Intel’s
newest 82440BX chipset with in an ATX size. This mainboard is designed for
both Pentium II and Celeron CPU’s It supports new architectures such as
high speed AGP graphic port, Ultra DMA/ 33, Bus Master IDE, SDRAM
memory and is expandable to a maximum of 1Gbyte of memory.
In addition to above features, NT928 P2BXD implements most advanced
technology such as synchronous Switching voltage regulator, CPU thermal
protection, CPU fan monitoring, System voltage monitoring, Over
current protection, Modem Wake Up, Keyboard power on, PS/2 mouse
power on, Debug sensor LED on board and user-friendly jumper-less
CPU speed selection.
The most unique feature of the NT928 P2BXD is its capability to debug
possible installation and peripherals faults onboard. When the CPU, DRAM,
FDD, or VGA cards have not been properly installed, a DIY user can isolate
problems through reading the Debug Sensor LED and instructions in the
manual. To professional system test engineers or maintenance engineers,
the Debug Sensor works as a Port 80 Debug Card for testing and
maintenance in lieu of the 80 Port Debug card.

Several options are provided for the CPU external clock. You are
recommended to restore to the default setting in case of instability when the
external clock exceeds 66MHz.
NOTE: System failure may occur if the CPU frequency is set incorrectly. To
solve this problem, press the "Insert" key on the keyboard to clear the
previously set frequency (i.e., restore the default frequency), and then reboot
the system.
z Switching voltage is applied, making the temperature lower and voltage
steadier.
z You don’t need to adjust Voltage in this Pentium II mainboard. It will
automatically send out one VID signal (Voltage Identification) to the
mainboard power supply to ask for the voltage it needs.

D. EDO/ SDRAM Installation Procedures:
z One 168-pin DIMM module can support up to 384MB at either
3.3V EDO (66MHz) or SDRAM (66MHz/ 100MHz).
z We recommend using SDRAM with Serial Presence Detect that are
compliant with PC-100. This will enable BIOS to detect the SDRAM size,
speed, voltage, its drive strength and number of row/column addresses,
to properly configure it to the system’s performance profile.

z First, verify the working voltage of the EDO/ SDRAM module in either
DIMM socket.
z This NT928 P2BX only supports 3.3V EDO/ SDRAM modules. The
following illustration shows you the difference between 3.3V and 5V to
ensure your correct selection of 3.3V DIMM module.
z You can set up the BIOS “Chipset Feature Setup” to the best working
condition based on the type of EDO/ SDRAM you are using.
z The BIOS DRAM default setting is 60ns. Change the BIOS “Chipset
Feature Setup” default setting to 50ns for better performance, only if
the chips on all modules installed are marked 50ns.

z Change nothing in the BIOS if EDO RAM is used. The BIOS
automatically detects the RAM type.
z MEMO for Installing System:
•Concerning memory setup, you can find out how to from “Chipset
Feature Setup” under BIOS setup. However, to avoid unstable system
operation or system hang, users without engineering background are
not suggested to change BIOS set up, other than CPU speed.
z The Dual Inline Memory Module (DIMM) must be 3.3 Volt and
Unbuffered Synchronus DRAM (SDRAM) 8MB, 16MB, 32MB or 64MB

that they are made compatible with the ISA-compatible SB16 sound
cards.
F. Note to BIOS Update
Do not update the BIOS if no abnormalities occur. However, if BIOS
update is needed, consult your dealer first. Prior to updating your BIOS,
you are recommended to save the original BIOS values.
1. Download the AWARD BIOS Flash Utility file (Awdflash.exe)
2. Download the BIOS file used by your identified mainboard model
(e.g., BXV110N.BIN)
3. Reboot your system (but do not run Himem.sys and Emm386.exe)
to execute the new BIOS program.
4. Execute these commands: Awdflash BXV110N.BIN
5. When this message displays: "Do you want to save BIOS (Y/N)?"
Type "N"
6. When this message displays: "Are you sure to program (Y/N)?"
Type "Y"
7. Turn off power to your system to clear the CMOS data.
8. Turn on the power to test if your system is running normal.

G. Keyboard/ PS/2 Mouse Power On and MODEM Ring on
z Make sure your ATX Power Supply can provide the full strength 5V
SB-signal required, which is nearly 750mA (Amperage). Your ATX
Power Supply should be able to supply at least 1 Ampere.
z If you are going to use the function of keyboard and PS/2 mouse
power on, the power-switch will be become disabled

H. System Health Monitor
This software is supplied on disk.
z Fan Monitoring:
The NT928 BXD provides for two fan connectors, one is for the CPU,
the other for an additional housing fan. When the fan’s speed is working
abnormally, there will be a warning (Speaker Alarm) issued through
application software such as SM10 (Small Icon for System Monitoring)
to notify user. The fan monitoring function is implemented by connecting
fan to 3-pin fan connector FAN1/ FAN2 and installing SM10 software.
Refer to Page 16 for jumper selection (System Health Monitor).

NT928 P2BXD - User’s Manual
20
z CPU Thermal Protection:
The NT928 P2BXD implements special thermal protection circuits.
When temperature is higher than a predefined value, there will be
warning (Speaker Alarm) through application software such as SM10
(Small Icon for System Monitor) to notify user. It is implemented
automatically by BIOS or SM10, no hardware installation is needed.
Refer to Page16 (System Health Monitor).
This mainboard also provides an option to use a CPU cooling fan with
Thermal Sensor on it. The CPU thermal sensor should be connected to
J16.
z System Voltage Monitoring:
NT928 P2BXD is featured with a voltage monitoring system. When you
turn on your system, this smart design will keep on monitoring your
system working voltage. If any of the required voltage is abnormal to a
component's standard, there will be Speaker Alarm though application
software SM10 (Small Icon For System Monitor) for a warning to user.
System voltage monitoring function monitors 5V, 12V, 3.3V and CPU
voltage. It is implemented automatically by BIOS and SM10, no
hardware installation is needed. Refer to Page 19 (System Health
Monitor)
