                U.S. Robotics 10/100 PCMCIA NIC TX
                  Packet Driver Installation


   1. Enable the U.S. Robotics 10/100 PCMCIA NIC TX

      USROPEN.EXE is the U.S. Robotics 10/100 PCMCIA NIC TX MS-DOS enabling program.  You
      have to run USROPEN.EXE to enable U.S. Robotics 10/100 PCMCIA NIC TX before bringing up
      the packet driver.  

      The syntax for USROPEN is:

         USROPEN [/IRQ=x] [/MEM=mm] [/IO=nnn] [/O] [/?]

         Valid options:
            x   = Interrupt number (3, 4, 5, 9, 10, 12, 15).
                  This number must not be in use by any other device in the system.
            mm  = Hex memory location (e.g. C0, C8, D0, D8).
            nnn = IO range (300, 320, 340, 360).
            U.S. Robotics 10/100 PCMCIA NIC TX requires 32 consecutive free I/O port addresses.  
            /O (overwrites current socket settings).
            /? Displays this screen.

         The default value for IRQ is 3.  The default value for IOP is 
         0x300.

      
         Example:  The following command enables U.S. Robotics 10/100 PCMCIA NIC TX with IRQ 5 and
                I/O port address 300:

            USROPEN /IRQ=5 /IO=300

      If you installed EMM386.EXE in CONFIG.SYS, please exclude memory 
      address range D000-DFFF or D400-D7FF from EMM386.EXE. The 
      U.S. Robotics 10/100 PCMCIA NIC TX DOS enabler USROPEN.EXE uses this space to read
      Ethernet ID and CIS from on-board flash memory.

        [Example]
           DEVICE=EMM386.EXE NOEMS X=D000-DFFF
                 

   2. Load the DOS Packet Driver USRPCM

      USRPCM syntax:

        USRPCM [-u] [-a] [-media] <PACKET_INT_NO> <INT_LEVEL> <IO_ADDR>
            Where:
            u             -- Unstall the driver.
            a             -- Enable Auto-Negotiation Mode.
            media         -- To set LineSpeed and Duplex.
                  The vaild setting is 10half, 10full, 100half or 100full.
                  10half  -- Forced to 10M, HalfDuplex Mode
                  10full  -- Forced to 10M, FullDuplex Mode
                  100half -- Forced to 100M, HalfDuplex Mode
                  100full -- Forced to 100M, FullDuplex Mode
            PACKET_INT_NO -- Packet driver interrupt vector.
            The reasonable rabge is 0x60 to 0x80
            INT_LEVEL     -- Hardware interrupt number.
            IO_ADDR       -- I/O Port Address.

  The only required parameter is the packet driver interrupt.  A packet
  driver needs to have a software interrupt assigned to it for other
  programs to access it.


        PACKET_INT_NO    This parameter specifies the software interrupt 
                         where the packet driver is loaded. It must be in 
                         the range 0x60 to 0x80.

                         This is a required parameter.
                         The value you specified for this parameter 
                         must start with 0x to indicate this is a 
                         hexadecimal value.

        [INT_LEVEL]      This specifies the hardware interrupt (IRQ) 
                         value.

                         Note that this value must match the IRQ value
                         you specified for USROPEN.EXE or the one
                         reported by USROPEN.EXE.

        [IO_ADDR]        This specifies the starting I/O address.

                         The value you specified for this parameter 
                         must start with 0x to indicate this is a 
                         hexadecimal value.

                         Note that this value must match the IOP value
                         you specified for USROPEN.EXE or the one
                         reported by USROPEN.EXE.

     Example 1:

           The following command loads the U.S. Robotics 10/100 PCMCIA NIC TX Packet Driver at
           software interrupt 0x60, I/O address 0x300, and hardware 
           interrupt 3.

           Since no command line option is specified, the connection
           type is set to Auto-negotiation.

              USRPCM 0x60 3 0x300

     Example 2:

           The following command loads the U.S. Robotics 10/100 PCMCIA NIC TX Packet Driver at
           software interrupt 0x60, I/O address 0x320, and hardware 
           interrupt 5, and the linespeed forced to 10Full.
                      
              USRPCM -10FULL 0x60 5 0x320

     Example 3:

           The following command unloads the U.S. Robotics 10/100 PCMCIA NIC TX Packet Driver.

              USRPCM -u 0x60

   A sample batch file START.BAT is included in this directory.  This 
   batch file first executes USROPEN.EXE and then brings up the packet
   driver.  To use this batch file on your computer you may
   have to modify the IRQ and IO_BASE values.
