Plug-and-Play (PnP) Network card
When installing a Plug-and-Play board into a Windows95 system
(example: 3COM EtherLink III 3C509), it is very easy: On
the next bootup, Windows95 detects the board and installs the
We should just check it, by verifying the driver in the
but since it is a Plug-and-Play board, the Properties in the
Network-applet to not even show the resources. For that we check
in the Control-Panel System-applet:
Windows NT4 does NOT have build-in Plug-and-Play support like
Windows95 (this feature has been announced by Microsoft for
Windows NT 5).
driver of NT4 works fine with
Sound-cards, but has
in my experience too much problems with PnP-network card )
FIRST: check in the "NT Diagnostics"
,tab:"Resources" for an available IRQ !
configure the Plug-and-Play board for NON-PnP-operation,
using the setup-floppy to disable Plug-and-Play and to define
MANUALLY the Port-address and IRQ.
Example: the Plug-and-Play Network-board: "3COM
EtherLink III 3C509".
Use a DOS-boot-floppy to boot up the system (because such
setup-programs do NOT work in a Command-prompt windows of Windows
NT4), then start up from the floppy:
"EtherDisk for the EtherLink III ISA (3C509) Network
Interface Card" the setup program "3C5X9CFG.EXE":
Select "Configure NIC", which will show for a new board
the factory defaults:
where "Plug-and-Play" is enabled.
DISABLE now Plug-and-Play.
Since your PC-BIOS did configure the card, it still has a
"grip" on it, so you will need to store the
configuration, then power-down and power-up your PC, which will
now not anymore configure the card (since it is not anymore a
Now configure the I/O-Address and IRQ (Interrupt Request Level)
to the values required for your system:
in this example: I/O-address = 320 and IRQ = 10. Save the
settings and restart NT.
Start now the Network installation:
||You can select, whether
to let the
system search for an installed
network board or whether to
select it yourself from the list.
||This board was selected
from the list.
||This board was detected
by the system.
|When using a copy of Windows NT with a ServicePack
install, all worked fine by just clicking on Next,
requested the NT4 CD-ROM to read the required drivers.
However, when using a copy of the original NT4
(without any Service Pack), I
had some trouble:
||I got stuck:
The system insisted to get the
floppy: "3COM Etherdisk
for EtherLink III"
insert into drive D: (which is my CD-ROM, from where I
run the NT-Setup).
I had no choice by to select "Cancel",let the
system continue and take care about this alter.
||I did NOT allow the
reboot, but went back to the Network, tab: Adapter,
deleted any installed adapter driver and then select
First, I tried to select the board from the list and then
to just select OK.
|But I got stuck again in
the request to read the "3COM Etherdisk" from
drive D:, so I had to "cancel" out again !
||Now, I try to add again
the board, but this time selecting "Have Disk"
||On the "Insert
Disk" dialog, change the, path now to the drive A:,
||From the list of drivers
on the floppy, select now the proper driver.
||This should now install
the proper drivers for the network board.
||You will be prompted to
define now the proper Port-address. In my example, I had
to changed it from 300 to 320.
Once you are now prompted to reboot, do it. On
bootup, you network should be operational.
