Problems printing the HTML manual
====================================
The on-line manual in HTML format is for on-line
viewing only. Printing this document may generate
formatting and pagination problems.
If you wish to print a copy of the HTML manual, check
3Com support WWW pages for information on downloading a
PDF version of the document.
FOR DOS AND WINDOWS 3.X
=======================
The LAN card works with laptops that contain Card
Services. If you are not running Card Services on
your system, please note that the 3C574 will work with
laptops that have an Intel PCMCIA (PC Card) controller
or compatible controller. If Card Services is not
installed, it might not work with other controllers.
You may override some driver configuration
parameters (IRQ, I/O base and CIS Memory
base address).
See the sample NET.CFG or PROTOCOL.INI
files on the Installation disk for proper syntax.
FULL-DUPLEX OPERATION
=====================
For NetWare ODI: The DOS ODI NetWare driver supports
full-duplex operation (sending and receiving data
simultaneously). WARNING: You MUST be connected to a
switched full-duplex Ethernet hub to use this feature
To enable this feature add the ODI Keyword "FULL DUPLEX" to the NET.CFG file.
For NDIS 2.0: To enable the NDIS 2.0
full duplex,add the Full Duplex key word
to the PROTOCOL.INI file:
ORIGINAL (Half Duplex):
[ms$el3c574]
DRIVERNAME=EL3C574$
MODIFIED (Full Duplex):
[ms$el3c574]
DRIVERNAME=EL3C574$
FULL-DUPLEX=YES
PLUG AND PLAY
=============
Plug and Play needs to be set to disable in CMOS
when using the DOS drivers with the LAN card.
Known Problems
==============
-------------------------------------------------------
AST Ascentia P Series
Problem. Card not working properly.
Action. The LAN card does not support
Ascentia P Series computers.
-------------------------------------------------------
Dell Latitude LM P100
Problem. Under Windows 95 OSR 2, this computer failed
some DOS diagnostics tests when the LAN card was
installed in the bottom slot and card was set for
I/O=300 and IRQ=10. Auto configure is unable to find
any usable IRQ.
Action. The DOS drivers should function properly even
though the adapter fails diagnostics with the settings
I/O=300 and IRQ=10.
-------------------------------------------------------
Tecra 440CX
Problem. On this computer running Windows 95 (OSR 2),
after removing and reinstalling the NDIS driver on
this platform forces the system into Safe Mode.
Action. Remove the LAN card, reboot, then reinsert the
LAN card after rebooting. This should allow normal
operation. Once normal operation resumes, running
ScanDisk should fix the problem.
-------------------------------------------------------
Micron Transport XKE
Problem. When running DOS Diagnostics (INSTALL.EXE) on
this computer, the system may hang during Starting
Configuration and Diagnostics, please wait. The
system may hang while loading the NDIS2 driver.
Action. In the BIOS, try setting Plug-and-Play to Yes
and reboot.
-------------------------------------------------------
Texas Instruments Extensa 660CD notebook computers
Problem. On this notebook computer, AUTO CONFIGURE
under INSTALL.EXE does not properly allocate resources
to the LAN card. AUTO CONFIGURE sets IRQ 5, I/O 300 on
the card, and with these settings there may be
intermittent self-test failures.
Action. Specify either IRQ 10 or 11 and I/O 300 for
the LAN card.
-------------------------------------------------------
Toshiba Satellite 220CDS
Problem.The DOS diagnostics program INSTALL.EXE does
not detect the LAN card.
Action. In the computer BIOS, set the PC Card
Controller mode to PCIC Compatible.
-------------------------------------------------------
Digital Hi Note VP 575
Problem. Unable to get the INSTALL.EXE, DOS ODI, or
NDIS 2.0 driver to load on a Digital HINOTE VP 575.
Action. The LAN card does not support the Digital
HINOTE VP 575 in DOS environments. Use the card under
Windows 95, where it will install and operate properly.
-------------------------------------------------------
Digital Hi Note Ultra
Problem. When Auto Configure is run as part of the DOS
Diagnostics, this computer cannot locate an available
IRQ. This problem has occurred with NDIS 4 under
Windows NT 4.0 and with NDIS 3.
Action. With NDIS 4 under Windows NT 4.0, use the
adapter settings I/O= 0x300H and IRQ=11. With NDIS 2,
use I/O=0x380H and IRQ=5.
-------------------------------------------------------
Sony VAIO PCG-808 and 505FX
Problem. After initial installation and setup, the
Configuration and Diagnostic program in INSTALL.EXE
cannot detect the LAN card.
Action. Power down the computer and reboot. After
this, the computer should be able to recognize the
card normally. For continued operation, be sure you
are using the correct settings for the LAN card:
I/O=300 and IRQ=10.
-------------------------------------------------------
Failure when modem card is installed
Problem. In DOS environments, the LAN card NDIS and
ODI drivers may not install correctly with some 3Com,
Megahertz, and US Robotics modem enablers.
Action. Reload the modem enabler using the following
line in CONFIG.SYS:
device=a:\enable.exe /c2 /im3 /sn
The switch /sn specifies the slot the modem uses and
will enable the modem only in that slot. N can be any
value A through H (for example, on Dell Latitude
computers, A is the top slot and B is the bottom
slot), so you would use /sA or /sB).
The /c and /im switches set the COM port and interrupt
level.
NDIS 4 DRIVER
=============
3Com includes the new NDIS 4 network driver on the
Installation disk.
The W95EL574.INF file loads the correct driver
for Windows 95 and the OEMSETNT.INF file loads the
correct driver for Windows NT.
The NDIS 4 driver works with Windows 95
OSR2 (version # 4.00.950b) and Windows NT 4.0,
but not standard Windows 95 or Windows NT 3.51.
The NDIS 3 driver works with Windows 95 OSR2,
Windows NT 4.0, standard Windows 95
(versions 4.00.950 or 400.950a), and Windows NT 3.51.
CHECKING THE DRIVER INSTALLATION
================================
After installing the NDIS driver under Windows 95,
if either of the LEDs are not turned on,
click Control Panel, click the System icon,
and select Device Manager to check the status
of the Network Adapter.

Novell NetWare Information
--------------------------
The Installation disk contains a Novell NetWare
DOS ODI Driver (3C574.COM).
If you are using 3Com's automatic
installation program,Intelligent Auto Install,
delete references to any other network adapter in
the AUTOEXEC.BAT file prior to executing
Intelligent Auto Install.
You should delete the NET.CFG file,
and a new one will be copied over.
Windows NT 4.0
--------------
The most common issue that we see
with the 3CCFE574BT/3CXFE574BT
adapter is finding valid resources
for the non-plug and play operating
system of Windows NT 4.0.
Below is a list of configurations that 3Com
Technical Support has found through
our cases to work.
Every situation is different, but the
below resources are a good starting
point.
In those instances, use whichever
resources work. The most common
symptom of a resource conflict is
either a freeze during startup or
no connection to the network.
