Chapter 1 Introduction

NEXCOM has developed a brand new product in its history, the Dual Pentium III FC-PGA, VIA Apollo Pr o
266 Chipset based all in one board with the ATX form factor. The NEX 6620A is the first model to be
available.

NEXCOM has developed a brand new product in its history, the Dual Pentium III FC-PGA; VIA Apollo Pr o
266 based all-in-one main board with the ATX form factor. A new product fam ily called the NEX series is
created. The NEX 6620A, name of this new product, is the first model to be available.

The major features of the NEX 6620A are as follows:

1. Dual Pentium III FC-PGA architecture with 133 MHZ FSB up to 1 G+Hz CPU clock.

2. Support DDR SDRAM with 4 DIMMs, memory size up to 4 GB.

3. On board built with VGA×1, intel 82559 Ethernet controller×2, PCI based Adaptec AIC 7899 dual c hannel
Ultra/ 160m.

4. AGP slot×1 for 4×AGP, and 32 bit/ 33 MHz PCI slot×5.

With all above f eatures equipped on boar d, T he NEX 6620A is one of the top performance DP server boar ds
in the world. So far, it’s still the smallest main board with so m any features integrated on the standard ATX
form factor . Without any add on cards, the NEX 6620A could out perf or m most of the ser ver boar ds bec aus e
there are 2x 100 Base TX Ethernet ports and 2x Ultra/ 160m SCSI channels on board. NEX6620A is
particularly suitable for the ISP server applications. A 2U chas s is c ould eas ily accom modate the NEX 6620A.
For larger server chassis, lik e the big tower, 5U, 6U, or even 8U rack mounted chassis, the NEX 6620A
could also be applied in these cases that are ATX compatible. T he reason to create the ATX ser ver line is
based on the fact that most produc ers use AT X for m f actors. W ith rigidly complying with ATX spec ifications,
the NEX 6620A could be applied in any case requiring the top server performance, as long as it’s ATX
compatible.

The NEX 6620A could also be positioned as the top performing workstation. With the on board AGP, the 4X
AGP slot reserved for any next generation 3D VGA/ Video accelerator cards, the NEX 6620A could out
perform any other DP architectures. Again, the standard ATX form fac tor is the greatest advantage of the
NEX 6620A for any workstation chassis, and it will help a lot f or the NEX 6620A to be widely accepted by the
power users in the compute-intensive workstation applications or the I/O intensive server applications.

NEX 6620A series can install to 4 Double Data Memory Module (DDR) DIMM sockets and supports the
maximum memory size up to 4GB. The architecture to provide the best choice for performance vs. stability

184 pins DDR SDRAM DIMM Module.
Please check the Position before Install the Module.

Installing DDR DIMM

To install the DDR DIMM’s, first m ak e sure the two handles of the DIMM s ock et are in the “open” pos ition,
i.e. the handles stay outward. Slowly slide the DIMM modules along the plastic guides in the both ends of
the socket. Then press the DIMM m odule down right into the sock et, until a click is heard. That m eans
the two handles automatically locked the memory modules into the right position of the DIMM socket

Remove DDR DIMMs

To take away the memory module, just push the both handles outward, the memory module will be ejected
by the mechanism in the socket.

Advanced Chipset Features Setup Menu

Since the features in this section are related to the chipset in the CPU board and all are optimized, you are
not recommended to change the default settings in the setup table, unless you know very detailed of the
chipset features.

This section allows you to configure the system based on the specific features of the installed chipset.
This chipset manages bus speeds and access to system memory resources, such as DRAM and the
external cache. It also coordinates comm unications between the conventional ISA bus and the PCI bus.
It must be stated that these items should never need to be altered. The default settings have been
chosen because they provide the best operating conditions for your system. The only time you might
consider making any changes would be if you discovered that data was being lost while using your system.

The first chipset settings deal with CPU access to dynamic random ac c ess memory (DRAM). T he def ault
timings have been carefully chosen and should only be altered if data is being lost. Such a scenario
might well occur if your system had mixed speed DRAM chips installed so that greater delays may be
required to preserve the integrity of the data held in the slower memory chips.

minus 33MHz. For example, if the Host Clock is
133MHz, the DRAM clock will be 100MHz.

HCLK+33M The DRAM clock will be equal to Host Clock plus

33MHz. For example, if the Host Clock is 100MHz,
the DRAM clock will be 133MHz.

clear any previously entered password from CMOS mem ory. You will be asked to confirm the password.
Type the password again and press <Enter>. You may also press <Esc> to abort the selection and not
enter a password.

To disable a password, just press <Enter> when you are prompted to enter the password. A message
will confirm the password will be disabled. Once the password is disabled, the system will boot and you
can enter Setup freely.

PASSWORD DISABLED

When a pass word has been enabled, you will be prompted to enter it every time you try to enter Setup.
This prevents an unauthorized person from changing any part of your system configuration.

Additionally, when a password is enabled, you can also require the BIOS to request a password every time
your system is rebooted. This would prevent unauthorized use of your computer.

You determine when the password is required within the BIOS Features Setup Menu and its Security
option (see Section 3). If the Security option is set to “System”, the password will be required both at boot
and at entry to Setup. If set to “Setup”, prompting only occurs when trying to enter Setup.
