Q31:
Where
can I find MAC address of your Ethernet LAN card?
There
are several ways to find the MAC address.
1. If you already installed this card in Windows, please execute
your "DOS prompt" (or Command Line Utility) to go to
C:\> Then type
C:\>ipconfig /all (press enter key)
You can find the display:
Ethernet adapter #1
Physical Address . . . . . 00-08-54-12-34-56
2. If you are using Win98, please Start->Run->winipcfg to see
Ethernet Adapter MAC address.
3. If you can find the driver floppy, please execute RSET8139.EXE to
see its MAC address.
4.. If you have not yet install the card, you may find a bar code
label on the card. Which is printed with MAC address.
|
|
Q30:
Why can't I use Windowss Network Neighbor to browse the network?
1.
The NIC doesn't connect to the network or there is a connection
problem between NIC and device.
- You can check the cabling, the cable should match the EIA568B.
- Check the device you connected. If the device is pure 100Mbs hub
or switch, the 10Mbps and 100Mbps will not communicate with each
other. Thus, you need a 10/100 dual speed hub or switch. Thus, you
need to use 10/100 Mbps dual speed hub or switch.
2.
If you can't browse the network, but you can find other computer.
Then there could be two reasons to cause this problem.
- In Control Panel -> Network -> Primary Network Logon. Change
the "Windows logon" to " Client for Microsoft
Networks".
- When you login to Win95/98, don't bypass user name and password.

Q29:
After install the driver of LAN card and restart PC,
this
PC can not access any other computer in network?
Check
all golden fingers of NIC are firm seated in the PCI slot of PC.
Check the cabling connection and LED of NIC.
Test the function of hardware in that PC by diagnostic program.
Boot up at DOS. Execute the "LSL" from diskette and
execute "RTSODI" from diskette. Check the messages that
echo in screen. If that IRQ will conflict with other devices, then
change the IRQ of PCI slot from "Auto" to "Fix"

Q28:
After install the driver of NIC and restart PC. This PC can access
any other computer
in network.
But system will hang out after transfer one large size file?
Check
the cabling connection and LED of NIC.
Test the function of hardware in that PC by diagnostic program.
Boot
up at DOS. Execute the "LSL" from diskette and execute
"RTSODI" from diskette. Check the messages about the
selected medium that echo in screen if it is correct.
|
|
Q27:
After install the driver of NIC and restart PC. This PC can access
any other
computer
in network. But performance is not good?
Some
BIOS setting will change to abnormal in PC, as BUS clock, normal PCI
BUS rate to ISA BUS should be 4:1, but check as 1:1
Power
on PC. Press Del key to setting CMOS. Select the Load
Default item in menu. Check above value again after re-boot.
|
|
Q26:
Why does my computer work incorrectly after I plugged the WOL cable?
Our
card has its own WOL cable, do not use another's cable to connect.
It could be caused blank screen and PC will not work properly.

Q25:
I install NIC driver correctly in Win95, but I can't ping or browse
any computer
in the
network. Why can't I use PCI NIC on VIA chipset's motherboard?
Although
VIA chipset is an Intel compatible product, it still needs a patch
program to let operating system enable and optimize its functions.
The most important function that will affect PCI NIC is IRQ Routing.
If you do not use this program to patch Win95/98, the resources of
IRQ will be unusable or assign correct one. It means that you
cant use the right IRQ to invoke the function of NIC.
You
can get the patch program from the web site http://www.via.com.tw/drivers/
|
|
Q24:
I had installed NIC and TCP/IP protocol, why can't I ping any other
computer in the net?
Please
do the following check to verify the cause of this problem.
1.
In Control Panel -> System -> Device Manager -> Network
Adapters, check the NIC status. If the NIC has Question mark or
Yellow mark, please remove existent driver and re-install it.
2. In Control Panel -> Network -> TCP/IP, select Properties
-> IP Address. Make sure the IP address setting and subnet mask
is suitable for your network environment.

Q23:
I can install 10M LAN card on NetWare 3.12, but I can't install
10/100M for
NetWare
3.12. Why?
Because
the driver of 10/100M LAN card follow Novell ODI Driver
Specification version 3.3, the NetWare version 3.12 and 4.10 server
must be patched to work with this driver. The servers of NetWare
version 4.11 and above do not need to be patched. The patching
method is described as below:
1.
Copy LOADER.EXE and LSWAP.EXE to the NetWare 4.10 server directory.
2. Execute LSWAP.EXE at MS-DOS prompt from server directory.
Usage:
LSWAP [loaderFilePath [serverFilePath]]
Default loaderFilePath = C:\NWSERVER\LOADER.EXE
Default serverFilePath = C:\NWSERVER\SERVER.EXE
|
|
Q22:
To install driver in Windows95 or 98 manually failed or select Cancel
when system
first time detect a PCI Ethernet device and request driver diskette.
How
can I install again?
Sometimes
after manually install driver, that register wrong resource will
cause the NIC driver work fail.
If user selects cancel, then device will be setting to unknown
device and latch the resource that should allocated to later
installed driver.
So check the device manager from control panel and check all unknown
device. If that unknown device is PCI Ethernet, then remove it and
reinstall NIC driver.

Q21:
Execute diagnostic program from the DOS prompt in Windows95/98 OS.
The
testing result display abnormal?
The
diagnostic program some functions will use the IRQ that will be used
in windows system. So will cause some function test failure.
Power
on PC and press "F8" key to show one menu screen. Select
command mode only from menu. Execute that diagnostic program at the
C:\ prompt. Then all test result will be correct.
|
|
Q20:
The system could not boot up from the network after install BOOTROM
chip at NIC?
The
default setting in NIC is disabled the BOOTROM function. User should
execute diagnostic program and change the setting in NIC to enable
and select the size of BOOTROM.
The
size unit of BOOTROM in NIC is byte (8 bits), and the size unit of
BOOTROM in chipset is bit. So if you use 512K-bit chip, then select
64KB in NIC. If you use 1M-bit chip, then select 128KB in NIC.
|
|
Q19:
What kind protocol support in BOOTROM function?
We
had support RPL protocol for boot up from network. That is available
at NOVELL and Windows NT system.
Currently had support another PXE for boot up from network.
|
|
Q18:
I want to use RPL(802.2) and 802.3 frame type at the same time.
But
when I bind 802.3 to server, the RPL user will fail to do remote
booting?
1.
Login Novell server with admin.
2. Create a file named BOOTCONF.SYS in the F:\login directory. The
format of BOOTCONF.SYS is as follow:
0x$$$$$$$$,00E07Dxxxxxx = DOS622.SYS
Where:
- 0x$$$$$$$$ is the 802.2 frame net (To get the number, you can run
"config" on Novell server, search the 802.2 frame type,
find "LAN protocol: IPX network $$$$$$$$.)
- 0080c8xxxxxx is the MAC address.
- DOS622.SYS is the Image file.
3.
In the BOOTCONF.SYS, the administrator needs to configure what MAC
needs what IMAGE file using what frame type, for example,
0x3B74A83A,00E07D5ac89d = DOS622.sys.
With
this BOOTCONF.SYS, they can use different image file with different
frame type.

Q17:
Can BOOTROM use client 32 for DOS to do remote booting?
If
you want to do remote booting procedure, you need to match two
conditions.
1. The driver of NIC has to support remote booting function.
2. The application also has to support remote booting function.
Since the *.LAN driver of our NIC doesn't support remote booting
function. The BOOTROM can't use client32 for dos to do remote
booting.
|
|
Q16:
I have two 10/100M LAN Card. One is RTL8139B chip another is RTL8139C
chip.
I have a BOOTROM on RTL8139B.
Can I use it on RTL8139C?
Yes.
|
|
Q15:
If user install old version NIC driver that for Windows95 at older
Windows98 OS,
then
will cause some error occurred.
Please
visit our web home page and download new version NIC driver. That
will fix above problem.
|
|
Q14:
If connect LAN Card to device that does not support N-Way function.
What
will happen?
If
that device does not support N-way, then user should change the
parameter of driver from default to fixed medium. But this setting
will disable the negotiation function. So be care check setting of
that other device.

Q13:
Why a twisted-pair cable works for 10Mbps hub but not work for 100Mbps
hub?
100M
bps runs at Cat. 5 twisted-pair cable will cause some cross-talk
signal. If the 3rd and 6th wire of RJ-45 connector are not belong at
the same twisted pair. That will cause problem with longer distance
as above 40 meters. User should check the wiring before install the
100Mbps network.
|
|
Q12:
Originally, a 10Mbps NIC works fine. When it replaced by 10/100Mbps
NIC,
it
doesn't work correctly. Why?
If
the 10/100Mbps NIC is OK and it can install correctly on the
operating system (I.E. Win95/98). It could be caused by wire
problem.
1.
10Mps NIC have more tolerance of signal noise ratio than 100Mbps NIC.
10Mbps can use CAT3 or CAT5 wire to connect, but 100Mbps needs
better wire quality and it is only allowed to use CAT5 wire.
2. There are four pairs of CAT5, each pair has its own definition.
You must make sure the twisted-pair of wiring is wire-1 and 2
twisted, wire-3 and 6 twisted, wire-4 and 5 twisted, wire-7 and 8
twisted.
|
|
Q11:
I want to use TP cable to connect two computers, but I don't want
to use a hub.
How
should I do?
You
can make a crossover cable, it can let you connect two computers
without any device (I.E. Hub or Switch).
|
|
Q10:
What is Nway Auto-Negotiation ?
Auto-Negotiation
is a mechanism that takes control of the cable when a connection is
established to a network device. Auto-Negotiation detects the
various modes that exist in the device on the other end of the wire,
and advertises it own abilities to automatically configure the
highest performance mode of interoperation.
Auto-Negotiation
acts like a rotary switch that automatically switches to the correct
technology, such as 10BASE-T, 100BASE-TX, 100BASE-T4, or a
corresponding Full Duplex mode. Once the highest performance common
mode is determined, Auto-Negotiation passes control of the cable to
the appropriate technology and becomes transparent until the
connection is broken.
Auto-Negotiation
leverages the proven link function of 10BASE-T to provide robust
operation over Category 3, 4, or 5 Unshielded Twisted Pair (UTP.)
top
|
|
Q09:
How does Nway Auto-Negotiation
operate?
An
Auto-Negotiation device advertises its abilities and detects the
abilities of the remote device by Fast Link Pulse. Once
Auto-Negotiation has received the link device's abilities in this
way and it receives acknowledgment that it is able to receive by the
link device.
Auto-Negotiation
compares the two sets of abilities and decides which technology to
connect. This decision is based upon a pre-agreed priority of
technologies. Auto-Negotiation attaches the highest performance
common technology to the medium and becomes transparent until the
link goes down or is reset.
|
|
Q08:
What is a wireless LAN Access Point?
-
AUTOMATIC CONNECTION
The primary benefit of Auto-Negotiation is the automatic connection
of the highest performance technology available without any
intervention from a user, manager, or management software.
- BACKWARDS COMPATIBILITY
If Auto-Negotiation exists at only one end of a twisted-pair link,
it finds that the Link device does not support the auto-Negotiation
mechanism. Instead of exchanging configuration information, it
examines the signal it is receiving. If Auto-Negotiation discovers
that the signal it is receiving. If Auto-Negotiation that the signal
matches a technology that the device supports that the signal
matches a technology that the device supports, it will automatically
connect that technology. This function, know as Parallel Detection,
gives Auto-Negotiation the ability to be compatible with any device
that does not support Auto-Negotiation, yet support: 10BASE-T,
100BASE-TX, or 100BASE-T4, Connection to any technology by Parallel
Detection other than those listed above is not supported by
Auto-Negotiation.
-
NETWORK PROTECTION
If
there is no common technology exists, Auto-Negotiation will not make
a connection. This assures preservation will not make a connection.
This assures preservation of network integrity and minimization of
network down time. In particular, Hub is a primary beneficiary of
this feature. For example, if a user connected through that switch.
However, if the hub has Auto-Negotiation, it would refuse the
connection and allow the rest of the networks to continue as usual.
In fact, with Auto-Negotiation in the hub, the network users are
protected from any connection that the hub cannot recognize of
accept.
-
UPGRADE PATH
New nodes on the market will have 100Mbps functionality also
traditional 10BASE-T. This means that there will be some latent
performance available as these new nodes are added to an old
10BASE-T network. When the performance issue becomes critical, the
latent ability can be tapped into by upgrading the hub.
Auto-Negotiation enables the upgrade to occur without reconfiguring
each node and/or each port on the new hub.
top
|
|
Q07:
How does Parallel Detection operate?
Auto-Negotiation
passes the signals presently on the receiver to the 100BASE-TX and
100BASE-T4 Link Monitor functions.
If Auto-Negotiation finds that exactly one Link Monitor function
shows that the link is good, then it can connect that technology to
the media.
Note, however, that this function is only carried out for 10BASE-T,
100BASE-TX, and 100BASE-T4. Future multi-mode devices will use
Auto-Negotiation as the basis of automatic mode switching.
Auto-Negotiation incorporates a modified 10BASE-T Link Integrity
Test function as inter-operate properly with installed 10BASE-T
devices. The modifications ensure that Auto-Negotiation can control
the function such that 10BASE-T devices are always correctly
detected.
|
|
Q06:
What is the priority hierarchy of Auto-Negotiation?
1.
100BASE-TX Full Duplex;
2. 100BASE-T4;
3. 100BASE-TX;
4. 10BASE-T Full Duplex;
5. 10BASE-T
|
|
Q05:
What is polarity reversal of a twisted-pair signal?
A
UTP cable consists of 4 pairs of twisted-pair cable, in which one
pair of wiring is used to transmit data and one pair is used to
receive data.
To resist the disturbance, each pair send both "positive"
and "negative" signals simultaneously, denoted as TX+ and
TX-, as depicted below:
Pin1 TX+ --> RX+
Pin3;
Pin2
TX- --> RX- Pin6;
Pin3
RX+ <-- TX+ Pin1;
Pin4
Pin5;
Pin6 RX- <-- TX-
Pin2;
Pin7;
Pin8;

Q04:
What
are the 100BASE-TX cabling standards?
100BASE-TX:
Fast Ethernet for Category 5 UTP; Max. Segment length: 100 meter;
Cable type: Catrgory 5 UTP cable using 22 or 24 AWG unshielded
twisted-pair wire with an impedance of 100 ohms.
Connectors: AT&T 258A RJ-45 connection, EIA/TIA-568B standard
|
|
Q03:
Does PCI Network cards support IRQ sharing ?
Yes,
our PCI cards support IRQ sharing.
To share an interrupt number for PCI devices, the follows must be
met:
1. The motherboard and its BIOS must support shared interrupts.
2. Both PCI devices must be able to share an interrupt.
If any of these requirements are not met then the NIC or another PCI
device will not work properly.

Q02:
REALTEK 8139/8139A/8139B/8139C had change many version.
What
difference between these modifications?
RTL8139
is first version for single chipset, that need one clean clock
source and work at DC 5V.
RTL8139A had add one Wake on LAN (WOL) function, that need to
expand the internal register of chipset and work at DC5V.
RTL8139B had built in one clock source ASIC, so change the clock
source from OSC to Crystal and support both DC 5V&3.3V.
RTL8139C had support expand ACPI from PCI BUS 2.2 Wake on LAN
from PCI BUS. Just work at green power DC 3.3V.
|
|
Q01:
What
operating system (NOS) that the LAN card supported?
DOS
ODI; Client32; NetWare ODI; DOS NDIS 2.0; OS2 NDIS 2.0;
NDIS 3.0/4.0/5.0 for Windows series; Linux; FTP packet driver;
SCO UNIX; MAC. OS
