3Com (R) Corporation EtherDisk (R) Diskette for The EtherLink 10 ISA NIC Family Release Notes and Frequently Asked Questions (FAQ) This file contains the release notes and answers to some frequently asked questions about the 3C509B to help you get the most out of your EtherLink 10 ISA Network Interface Card (NIC). This information is updated regularly on 3com's world wide web site (www.3com.com). Release Notes ------------- EtherDisk 6.1 has been revised and is split into two diskettes. EtherDisk #1 contains all the files necessary to install the EtherLink 10 ISA in Windows 95/98 or Windows NT. This includes a Windows based GUI installer for Windows 95/98 and a post installation configuration and diagnostic tool, accessible from a system tray icon and from the Windows Start Menu, for both Windows 9x and Windows NT environments. Both NDIS3 and NDIS4 miniport drivers are included and appropriately installed in Windows 95/98 and Windows NT 3.51 and 4.0. EtherDisk #2 contains the software that was on EtherDisk 6.0. This includes installation for NetWare versions 3.X and 4.X, various DOS based network operating systems, IBM OS/2, and the packet driver. Full duplex support for the 3C509B has been added to the NetWare server and Windows NT/95/98 drivers. Control of the full duplex feature is provided in the configuration and diagnostic program. Full duplex operation improves overall network throughput on twisted pair (TP) networks. A boot ROM for the EtherLink 10 ISA product family is available from your network supplier. The 3C5-TriROM supports NetWare boot, RPL, and BootP network boot protocols. The EtherLink 10 ISA, formerly known as the EtherLink III, has gone thru a product name change. The products are fully compatible and the terms EtherLink III and EtherLink 10 ISA can be used interchangeably. Important --------- Not all NICS and hardware product features are supported with this EtherDisk. The 3C509 and 3C509B in both classic and Plug n Play modes are fully supported. The 3C509 and 3C509B in EISA mode are not supported. The 3C579 EISA NICs are not supported. The 3C529 MicroChannel NICs are partially supported. In Windows 95 and Windows NT, the NIC driver can be installed and removed, but the windows diagnostic program and tray icon are not loaded. To make configuration changes or test a 3C529, use the DOS diagnotic on diskette #2. The Windows 95/98 and Windows NT full port drivers have been combined into a single miniport driver. It is important to use this driver if you use 3Com's DRMON network management software. This driver will give better performance when the DRMON client agent is used. When converting from past drivers to this driver, or installing this driver for the first time, several things must be considered. Windows NT ---------- Older drivers may be updated directly to the miniport driver. However, if this driver will be used in a multiprocessor Windows NT 4.0 system, then you must update to service pack 3 or newer. Failure to update to service pack 3 may cause your system to crash. If you are installing more than one EtherLink 10 ISA in a Windows NT 4.0 system, you need to follow the instructions in the manual or the Windows NT installation notes (WINNT.TXT). Failure to do so could result in having to reinstall Windows NT 4.0. This version of the EtherDisk does not contain driver support for Windows 2000. In order to install the 3C509B in the Windows 2000 environment use the driver supplied by Microsoft that is native to Windows 2000. Windows 95/98 ------------- Install Windows 95/98 before installing the EtherLink 10 ISA NIC. After installing Windows 95/98, run PREINSTL on EtherDisk #2 and follow the instructions. Older, full port drivers (ELNK3.VXD) cannot be updated directly to the miniport driver due to the driver name change. To update your older driver you must follow the update procedure in W95NDIS3.TXT on EtherDisk #2. For users upgrading from EtherDisk v6.0x driver set please refer to W95NDIS3.TXT for specific upgrade instructions. Windows For Workgroups (WFW) ---------------------------- For Windows for Workgroups requiring the standard NDIS3, 32-bit protected mode diver (ELNK3.386), support refer to the file WFWNDIS3.TXT in the HELP directory on EtherDisk #2. For users requiring real-mode, NDIS2 support (ELNK3.DOS) for Windows for Workgroups refer to the HELP file WFWNDIS2.TXT for installation instructions. Users requiring DOS ODI support (3C5X9.COM) in a Windows for Workgroups environment refer to the HELP file WFWNETWR.TXT for installation instructions. Frequently Asked Questions -------------------------- Q: I installed an EtherLink 10 ISA (3C509B) NIC in my computer, but neither the diagnostic and configuration program nor the driver can find the NIC. What's wrong? A: Your computer's BIOS is issuing a series of I/O instructions that causes the 3C509B to think it's going to be activated as a Plug 'N Play (PnP) device. Unfortunately, the NIC waits for the PnP series to complete and ignores the "classic" or "legacy" method for discovering an EtherLink 10 ISA NIC. The fix for this problem is very simple. Follow the steps below: 1 - Boot a minimal DOS setup, making sure that no EtherLink 10 ISA drivers are loaded. 2 - Put this EtherDisk in the diskette drive and type A: at the DOS prompt. 3 - Enter PNPDSABL at the DOS prompt. The configuration and diagnostic program will execute twice. The first time it executes, the configuration and diagnostic program "kicks" the EtherLink 10 ISA out of its PnP wait state. During the second execution, it disables Plug 'n Play. The final message displayed will be: "The 3C5X9 adapter, adapter number 1, was successfully configured" 4 - Finally, remove the EtherDisk from the diskette drive, and turn the computer power off, then on. It is also possible that your computer contains a device that uses I/O address 0x110. If possible, move the device at I/O address 0x110 to some other non-conflicting address. All 3Com drivers and the diagnostic software use I/O address 0x110 as the default. If the conflicting device cannot be moved away from address 0x110, then the driver (or diagnostic) can be made to use another I/O address for discovery. Look at the documentation for each driver for details. Q: Why does a red X occur on the 3Com Icon in the system tray in the lower right hand corner of the screen? A: The red X indicates that the NIC is not connected to network. For Twisted pair installations that means the NIC is not detecting linkbeat. If this occurs check the cabling and make sure the NIC is set to use twisted pair. This may also occur if the NIC is configured for legacy mode and the Input/Output Range under the Resource tab in the properties of the EtherLink 10 ISA do not match the actual I/O Base Address of the NIC. To check the NICs I/O Address run the diagnostic/configuration utility program. Q: I noticed that my system hangs when performing the GUI diagnostics when the 3C509B is in legacy mode, but they work when the NIC is configured for Plug 'n' Play. What is the problem? A: This can occur if the resources are not configured properly in the device manager for the 3C509 when configured for legacy mode. Check the IO Base Address under the Configuration tab for the GUI diagnostics for the 3C509 and make sure they match the settings under the Resources tab in properties for the 3C509 in the device manager. Q: My system does not recognize the 3COM 3C509B NIC. What do I do? A: If your computer has a PnP BIOS, and it doesn't find the 3C509B NIC, either the NIC has the PnP feature disabled or the BIOS is unable to find the NIC due to the problem described in the previous FAQ. Boot the computer to a minimum DOS configuration. Put this EtherDisk in the diskette driver and type A: at the DOS prompt. Enter 3C5X9CFG at the next DOS prompt. If the diagnostic program emits an error saying that no EtherLink 10 ISA adapters were found, follow the instructions in the answer to the previous FAQ. If the diagnostic finds the NIC, enter the configuration menu and examine the state of the Plug 'n Play function. If PnP is set to disabled, change it to enabled, and save the configuration by clicking the OK button. Q: When running the Windows GUI diagnostic I receive a warning that states: "By running the diagnostics at this time unpredictable results may occurs". What is the problem? A: This warning generally appears as the result of 2 conditions: 1) Check to make sure the TCAATDI diagnostic (TCAITDI diagnostic for Windows NT users) is installed. Check in the Network Control Panel Applet to make sure the TCAATDI diagnostic appears under installed components. For Windows NT users, this can be observed under the Services tab. If this service is not installed then re-install the NIC drivers. 2) The NIC driver has not been installed properly. Check in the Device Manager and make sure the 3Com EtherLink 10 ISA does not have a yellow ! or a red x. Q: I have installed a 3Com EtherLink 10/100 PCI (3C90x) with the 3C509B and now I am having problems with the Windows diagnostic. What is wrong? A: This version of the EtherDisk (v6.1) for the EtherLink 10 ISA (3C509B) is compatible with the Windows GUI diagnostic from the EtherDisk v4.0x for PCI. If later drivers are installed for the EtherLink 10/100 PCI problems will occur when running the diagnostic. In this installation it is recommended not to use the diagnostic. This is due to a change in the diag architecture implemented with the PCI product that is not supported with the 3C509B. If you need to run the diagnostic use the DOS utility (3C5X9CFG.EXE) on EtherDisk #2. Q: When I load the DOS drivers from EtherDisk 6.1 for the 3C579 (EISA) or 3C529 (MCA) the driver bannner shows the 3C509(B), does this driver set support non-ISA products of the 3C5X9 product family? A: While these drivers will detect non-ISA NICs of the 3C5X9 family, this driver set was targeted for the ISA product and was not certified on non-ISA products. For the most recent certified drivers for the non-ISA 3C5X9 product family members refer to the 3Com web site (www.3com.com). Q: Can a 3C509B NIC be installed in an 8 bit slot? A: Yes. The 3C509B NIC can be installed in any 8-bit slot. However, the 3c509B will only work in a computer with a 286 or higher processor. Q: What do I need to do to exclude within EMM386 for the 3C5X9 NIC? A: EMM386 does not need an exclusion for the 3C509 NIC because the card does not use shared memory. Q: I installed the 3C509 in an ISA slot but I get an error that states the NIC is configured for EISA mode. How do I fix this problem? A: Insert the 3C509 NIC in an EISA slot and use the 3Com configuration utility to reconfigure the NIC's I/O address mode from EISA to non-EISA. Save the setting for the NIC and exit. This will return the NIC to the default mode, which is ISA. Q: Where do I get the latest drivers? A: The latest 3Com drivers can be found on any of these three online locations: 3Com's CompuServe forum (go NetForum) 3Com bulletin board service (BBS) 3Coms World Wide Web site (http://www.3Com.com). Q: My system has PCI slots and ISA slots. When I install the NIC, I get an error stating there is an interrupt conflict or, the system crashes when the NIC driver loads or the diagnostic executes the interrupt test. How do I fix this problem? A: Make sure that the PCI configuration, usually found in the BIOS setup of the computer, is not allocating the interrupt request level (IRQ) for use by the PCI bus. You must either not allow the IRQ to be used for a PCI slot or move the IRQ for the 3C509 ISA NIC to a level that won't conflict. Q: I am getting a conflict message when loading a packet driver. How do I fix this problem? A: When loading the packet driver, the software interrupt may need to be changed to avoid conflict. Packet drivers information is found in the \HELP\PACKET.TXT file on EtherDisk #2. Q: I am using VLMs for NetWare and Windows/ WFW. How do I configure my Windows environment to support VLMs? A: If your NetWare shell version within Windows doesn't support VLMs, you will need to download the NetWare Client Kit for Windows/ DOS from Novell's Netwire or run the Intelligent Auto Installation utility on EtherDisk #2. This utility will update your Window's support for NetWare by installing the latest windows files. Q: I am using Microsoft drivers and having trouble connecting the NIC in WFW. A: Use the 3Com drivers instead of Microsoft drivers. There are help files to assist with these installations, and the install program allows updating these drivers. Q: Can I do a Windows Custom install with the 3C509 using the drivers from EtherDisk 6.1? A: For users requiring a Windows custom install refer to the W95NDIS3.TXT file on EtherDisk #2 in the HELP directory for details. Q: My NetWare workstation will not connect to the file server. How can I fix this problem? A: The most common problem is the client and server are using different NetWare frame types. The default frame type for NetWare 4.x and 3.12 is 802.2, where NetWare 3.11 used 802.3 as the default frame type. To verify this problem, 1 - Verify the frame type of the file server. This information is in the AUTOEXEC.NCF file on the server. Check to see which frame types are supported by the server. 2 - Edit the NET.CFG file to set the proper frame type. All the valid frame types are shown below: Link Driver 3C5X9 Frame Ethernet_802.2 Frame Ethernet_802.3 Frame Ethernet_II Frame Ethernet_Snap Q: I have Award BIOS 4.50PG and I can not get into the 3Com configuration program. A: With the Award 4.50pg BIOS, you could either update the BIOS to a more current version or execute PNPDSABL.BAT to disable the PnP of the NIC. Q: The "NIC Details..." option under the General tab of the GUI diagnostic for the 3C5009 does not always show the correct transceiver type, when AUTO media selection is determined. What is the problem? A: The transceiver type initially shows the EEPROM setting which is not always accurate. The transceiver setting will be updated after running the diagnostics, and will reflect the accurate value. Q: Are there any command line functions or options for the 3Com diagnostics program? A: Yes. The INSTRUCT.TXT file located in the \HELP sub-directory on EtherDisk #2 explains in detail the possible options and functions of the diagnostics program. Q: The 3Com Tray Icon does not appear on my computer can I run the Windows GUI diagnostic or enable it so it does appear in the system tray? A: The GUI diagnostic and Help can be executed from the Windows Start Menu. It is accessible from Start -> Programs -> 3Com NIC Utilities -> 3COM NIC DOCTOR. To enable the tray icon execute the 3Com NIC Doctor as explained earlier, and select the "Show Icon in System Tray" under the General tab. Q: Can I remove the 3Com NIC Doctor from the System tray in Windows? A: Yes, this can be done by executing the 3Com NIC Doctor GUI diagnostic as explained in the previous FAQ and deselect the "Show Icon in System Tray" under the General tab. Q: When I click on the "Show Icon in System Tray" check box to deselect it, an "This program has performed an illegal operation...", what happened? A: This problem occurs intermittently and from testing does not have a system impact. Ignore this error, and follow the instructions included in this file if you wish to enable the tray icon. Q: Are there MSL drivers for the 3Com 3C5X9 NIC family? A: No, the 3C5X9 NIC cannot be used as a MSL with Novell. Q: When configuring multiple NICs with Windows GUI diagnostic, the new settings do not always appear under the Configuration tab, what is the problem? A: The GUI diagnostic may not show the current configuration changes in a multiple NIC configuration. They will appear upon restart of the system. Q: Where can I get additional tech tips? A: To keep up with support of newer platforms, look to the 3Com Web site or the 3Com Fax Back system (408-727-7021) for additional tech tips.
