GENERAL INFORMATION
*********************************************************************

1. Slow or Dropped Connection on a 10/100 Switch or Hub

Windows Me, 98, 95:

The switch may be forced to 10 Mbps. Disable Auto Polarity:

       1. Open Control Panel>Network
       2. Double click the LAN PC Card.
       3. Click the Advanced tab.
       4. Select Automatic Polarity Selection.
       5. Select Disable.

Windows 2000, NT:

       1. With the Installation CD in the CD-ROM drive, browse
          to D:\AUTOPL\AUTOPL.EXE, where D: is your CD-ROM drive.
       2. Double-click AUTOPL.EXE.
       3. Select "3Com LAN Card".
       4. Click "Disable".
       5. Click "OK" and "Close".

---------------------------------------------------------------------
2. Windows 2000 Drivers

The 3Com Installation CD does not contain drivers (.INF) for Windows
2000. Check the 3Com support Web site (www.3com.com/support) for new
drivers as they become available.

---------------------------------------------------------------------
3. Connection LED is Lit when the LAN PC Card is Not Connected

The LEDs on the LAN PC Card work correctly when the line speed is set
to Auto Detect. When the line speed is set to anything else, the 
LED is lit all the time, even when no cable is connected. This means
that you cannot determine the status of the connection from the LED
state when the line speed is not set to Auto Detect. 

---------------------------------------------------------------------
4. 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, the PC Card will work
with laptops that have an Intel PCMCIA (PC Card) or compatible 
controller. If Card Services is not installed, the PC Card might not
work with other controllers.

You may override IRQ, I/O base, and CIS Memory base address 
configuration parameters.  

See the sample NET.CFG or PROTOCOL.INI files on the Installation 
disk for proper syntax. 

NOTE: If either the interrupt or the I/O address is overridden, 
the other must be overridden also.

---------------------------------------------------------------------
5. Full-Duplex Operation

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.

NDIS 2.0: 
   To enable the NDIS 2.0 full duplex, add the Full Duplex Keyword 
   to the PROTOCOL.INI file:

   ORIGINAL (Half Duplex):
    [ms$el3c574]
    DRIVERNAME=EL3C574$

   MODIFIED (Full Duplex):
    [ms$el3c574]
    DRIVERNAME=EL3C574$
    FULL-DUPLEX=YES

---------------------------------------------------------------------
6. Plug-and-Play

Plug-and-Play must be set to "disable" in CMOS when using the DOS
drivers with the LAN card.

*********************************************************************
ISSUES AND ACTIONS
*********************************************************************

7. AST Ascentia P Series

Issue:
Card not working properly.

Action:
This LAN card does not support Ascentia P Series computers.

---------------------------------------------------------------------
8. Dell Latitude LM P100

Issue:
Under Windows 95 OSR 2, this computer failed some DOS diagnostics
tests when the LAN card was installed in the bottom slot and the 
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.

---------------------------------------------------------------------
9. Tecra 440CX

Issue:
When running Windows 95 OSR 2, after removing and reinstalling the
NDIS driver, the system is forced into into Safe Mode.

Action:
Remove the LAN card, reboot, then reinsert the LAN card. This 
should allow normal operation. Once normal operation resumes, 
running ScanDisk should fix the problem.

---------------------------------------------------------------------
10. Micron Transport XKE

Issue:
When running DOS Diagnostics (INSTALL.EXE), the system may hang 
during Starting Configuration and Diagnostics. It also may hang
while loading the NDIS2 driver.

Action:
In the BIOS, set Plug-and-Play to Yes, and reboot.

---------------------------------------------------------------------
11. Texas Instruments Extensa 660CD Notebook Computers

Issue:
Auto-Configure under INSTALL.EXE does not properly allocate 
resources to the LAN card. Auto-Configure sets IRQ 5 and I/O 300. 
With these settings, intermittent self-test failures may occur.

Action:
Specify either IRQ 10 or 11 and I/O 300 for the LAN card.

---------------------------------------------------------------------
12. Toshiba Satellite 220CDS

Issue:
DOS diagnostics program INSTALL.EXE does not detect the LAN card.

Action:
In the computer BIOS, set PC Card Controller mode to PCIC Compatible.

---------------------------------------------------------------------
13. Digital Hi Note VP 575

Issue:
Unable to get the INSTALL.EXE, DOS ODI, or NDIS 2.0 driver to load.

Action:
The LAN card does not support the Digital Hi Note VP 575 in DOS 
environments. Use the card under the supported Windows environments,
where it will install and operate correctly.

---------------------------------------------------------------------
14. Digital Hi Note Ultra

Issue:
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.

---------------------------------------------------------------------
15. Sony VAIO PCG-808 and 505FX

Issue:
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.

---------------------------------------------------------------------
16. Failure When Modem PC Card is Installed

Issue:
In DOS environments, the LAN card NDIS and ODI drivers may not 
install correctly with some 3Com, Megahertz, and U.S. 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.

*********************************************************************
NDIS 4 DRIVER
*********************************************************************

17. Driver Information

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 OEMSETUP.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.

---------------------------------------------------------------------
18. Checking the Driver Installation

After installing the NDIS driver under Windows 95, if either of the
LEDs is not lit, go to Control Panel>System icon>Device Manager to
check the status of the LAN PC Card.

If Network Adapter has a yellow exclamation mark, an incorrect NDIS
driver was loaded from the Installation disk. Remove the incorrect
driver and install the correct driver. 

---------------------------------------------------------------------
19. Installing the NDIS 4 Driver for Windows 95 OSR2 

You must use the latest NDIS.VXD to use the NDIS 4 driver.

21. General 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.  

Delete the NET.CFG file, and a new one will be copied over. 

---------------------------------------------------------------------
22. Windows NT 4.0

The most common issue with the FE574BT PC Card 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 to work. Every  situation is different, but these resources are a good 
starting point.  

Note:  3Com Technical Support does not guarantee these working 
configurations in these laptops. We have found these resources to 
work in specific situations, but performance may vary based on your
notebook's configuration. 

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.
