NDIS Driver Installation Overview For Ethernet PCMCIA Adapter The drivers contained in the directory MSLANMAN.DOS , and NDIS are for use with Ethernet PCMCIA adapter. They are used with Com's 3+Open, Microsoft's OS/2 LAN Manager OEM, distribution packages Release 1.x or 2.x, and other compatible OEM versions of LAN Manager. The drivers named "ETHPCM" conform to the Network Driver Interface Specification (NDIS) defined by Microsoft/3Com. File Descriptions: \MSLANMAN.DOS\DRIVERS\PCMCIA\ACCNE\ ETHPCM.DOS The DOS NDIS MAC driver PROTOCOL.INI A sample section of a PROTOCOL.INI file \MSLANMAN.DOS\DRIVERS\NIF\ ACCNE.NIF Network Information File \NDIS PCMCIAD.NIF Network Information File for LAN Server (DOS) READ.ME ETHPCM.DOS The DOS NDIS MAC driver OEMSETUP.INF Network Information File for Windows for Workgroups 1. Installation Procedure Proper installation can be verified by running the diagnostic program CARDTEST.EXE in \DIAG directory under DOS. 2. Sample protocol.ini file and parameters [ACCNE_NIF] ; Default section of protocol.ini file for the Adapter drivername = ETHPCM$ irq = 5 iobase = 0x300 ; End of this sample file Several parameters are included in the ACCNE_NIF section of the PROTOCOL.INI file. However, the only parameter that must be specified is the "drivername". The other parameters use the values detected by the driver. irq Specifies the interrupt channel used by the adapter. Acceptable values for this parameter are 2, 3, 4, 5, 10, 11, 12 ,and 15. However, some of the mentioned adapters do not support all the acceptable values. iobase Specifies the iobase address used by the adapter. This parameter is given in hexadecimal values. Acceptable value for this parameter are 0x240, 0x280, 0x2C0, 0x300, 0x320, 0x340, 0x360. 3. Additional Parameters in the protocol.ini file for the NDIS Driver Configuration Keyword Parameter MaxMultiCast 1 .. 1000 Default 10 Maximum number of MultiCast Addresses. This configures the size of the MultiCast Address Table. MaxRequests 6 .. 64 Default 8 Maximum number of outstanding General Requests. This configures the size of the General Request Queue. MaxTransmits 6 .. 64 Default 12 Maximum number of outstanding TransmitChain commands. This configures the size of the TransmitChain Request Queue. ReceiveChains 6 .. 96 Default 12 Maximum number of outstanding ReceiveChain commands. This configures the size of the ReceiveChain Request Queue. ReceiveBuffers6 .. 96 Default 12 Configures the number of the Receive buffers in the Receive Buffer Pool. TransmitBufSize 128 .. 1514 Default 1514 Configures the size (in bytes) of buffers in the Transmit Buffer Pool. ***** Note : Values for the preceding parameters are seldom changed by the user. Most of the time, the default values are used. ***** Trademarks: Microsoft OS/2 LAN Manager is a trademark of Microsoft Corporation. 3Com, 3+, 3+Open and EtherLink II are registered trademarks of 3Com Corporation. TROUBLE SHOOTING and ERROR MESSAGES If you have a problem, run "CARDTEST" program to determine if any parameters are in conflict. ERROR MESSAGE: ERROR: Adapter card not found or I/O port error. There are two possible reasons for this error: (1) The Adapter card is not installed correctly in its slot, (2) The I/O port failure is caused by an incompatability between the computer and the adapter. ERROR: Incorrect Media Setting or Bad Tranceiver The following are the possible reasons for this error: (1) The tranceiver is bad. (2) The cable is broken. (3) The cabling is not attached. Please run the CARDTEST program to determine the reason for the error.
