Installing the Driver
=====================
1. Install the NIC in your PC and connect to the network.
Turn the PC power on.
The Found New Hardware screen appears, and then the Found New
Hardware Wizard starts.
2. Click Next.
The Install Hardware Device Drivers screen appears.
3. Select Search for a suitable driver for my device (recommended),
and then click Next.
The Locate Driver Files screen appears.
4. Select the CD-ROM drives option, clear any other checked options,
and click Next.
The Driver Files Search Results screen appears. Windows finds the
driver on the CD.
5. Click Next.
Files are copied, and then the message: Windows has finished
installing the software for this device appears.
6. Click Finish.
Verifying Successful Installation
=================================
To verify that the NIC was installed successfully:
1. Right-click the My Computer icon, and then click Properties.
2. Select the Hardware tab, and then click Device Manager in
the middle panel.
3. Click the + symbol next to Network Adapters in the list.
The absence of a red X or a yellow exclamation point (!) next to
the name of the NIC name confirms successful installation.
Installing Multiple NICs
========================
To install multiple NICs in a PC running Windows 2000, install
and configure each NIC individually following these steps:
1. Install the first NIC in your PC and connect it to the
network, as described in Installing the Driver.
CAUTION: Do not physically install the second NIC
in your PC until you complete the driver
installation for the first NIC, following
the steps below.
2. Turn on the power to the PC and start Windows.
3. Insert the EtherCD when prompted, and then click OK.
4. Follow the prompts on the screen to install the network
driver.
5. After the network driver is installed, restart the PC.
6. After the PC restarts, exit Windows and turn the power off.
Make sure that the PC is unplugged.
7. Install the second NIC in your PC and connect it to the network.
8. Plug in the PC power cord, turn on the power, and then start
Windows.
Windows detects the second NIC. The second NIC uses the same
network driver as the first NIC. You are not prompted for the
EtherCD. When Windows starts, the second NIC appears under
Network adapters in the Device Manager.
9. Repeat the process for each additional NIC to be installed.
Removing NIC Software
=====================
1. Right-click the My Computer icon.
2. Select Properties on the pop-up menu.
The System Properties screen appears.
3. Select the Hardware tab.
4. Click Device Manager in the middle panel.
The Device Manager screen appears.
5. Click the + symbol next to Network adapters.
6. Double-click 3Com 10/100 PCI NIC w/3XP (3C990B).
A screen with the name of the NIC in the title bar appears.
7. Select the Driver tab, and then click Uninstall.
The Confirm Device Removal screen appears.
8. Click OK.
The Device Manager screen appears.
9. Close all open windows, exit Windows 2000, shut down the system,
turn the PC power off, and remove the NIC from the PC.

Definitions of the Keep-Alive and Wakeup Parameters
===================================================
Wake-on-MagicPacket
Enables the NIC to wake up upon receipt of an AMD MagicPacket(tm).
Wake on Link
Allows the NIC to wake up the host if the link state changes,
whether the change is loss of link or restoration of link.
It can take up to 6 seconds from the time the link is lost
until the time the NIC wakes up the host, so that the NIC
doesn't wake up the host for transient errors.
Wake on Arp
Allows the NIC to wake the host when an ARP request directed
to the host is received. Only directed ARPs will cause this
wakeup, an ARP request aimed at a broadcast IP address will
not cause the wakeup.
Wake on Ping
Allows the NIC to wake the host when a ping (ICMP echo request)
packet, directed at the host's IP address, is received. Only
directed pings will cause this wakeup, a ping request aimed at
a broadcast IP address will not cause the wakeup.
Wake on Timer
Allows the user to specify a time from shutdown/standby/suspend
that the NIC should wake up the system. Example: if the user
specifies 10 minutes, then 10 minutes after the next shutdown/
standby the NIC will wake up the system.
Wake on Error
Allows the NIC to wake up the system whenever it runs into a
problem performing the other requested wakeups or keep-alives.
For example, if the NIC is configured for DHCP lease renewal
and is unable to get a response from the server, it would
wake on error. If the NIC is configured for Wake-on-Magic
Packet and the link were lost, the NIC would wake-on-error, as
it would be unable to look for Magic Packets(tm).
DHCP lease renewal
The NIC will take over maintaining the IP address lease from
the lease server. It will not allow the server to give it a
different address, only to renew the address in effect at the
time of shutdown. Depending on the DHCP server used,
Respond-to-Arp or Respond-to-Ping may need to be enabled, as
some servers use ARP and Ping messages as part of the renewal
process. DHCP lease renewal is not supported under Windows 2000
because Windows 2000 does the renewals itself and the NIC has
been instructed by Microsoft not to interfere with that.
Mac Keepalives
The NIC transmits innocuous ethernet Hello packets
every 1 minute. The purpose of this feature is to
maintain the NIC's presence on switches that age out
unused addresses and do not at least forward an ARP
request.
Respond to Arp
Allows the NIC to send an ARP response when an ARP
request directed to the host is received. Only
directed ARPs will receive responses. An ARP request
aimed at a broadcast IP address will not be answered.
Respond to Ping
Allows the NIC to send a Ping response (ICMP echo
response) when a Ping request (ICMP echo request)
directed to the host is received. Only directed Pings
will receive responses; a Ping request aimed at a
broadcast IP address will not be answered. Fragmented
Pings will only have their first fragment returned,
not the entire data payload.

Download Driver Pack
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
