Install the DOS Driver for Aironet

Complete these steps in order to install the DOS driver:

  1. Build the config.sys file in this way:

    DEVICEHIGH=A:\DICRMU01.SYS /MA-D000-D7FF /SH=1 /IX=5,10,11,15
    SHELL=COMMAND.COM /e:512 /p

    The IBMDSS14.SYS, IBMDOSCS.SYS and DICRMU01.SYS files are PCMCIA Card and Socket Services for the sample model IBM laptop. Substitute appropriate files from the laptop manufacturer as appropriate.

  2. Customize the included cscpkt.ini file to individual needs:

            ;Initialization file for Infrastructure operating mode
            ; NOTE: The following are some keyword parameters that may
            ;be modified.  Any commented or omitted keyword parameter
            ;assumes the factory default.  For most situations the
            ;factory defaults will be appropriate.  In situations where
            ;the factory default needs to be modified, uncomment or add the
            ;keyword parameter line and set the appropriate keyword value.
            SSID="network_ssid"     ;Must match Access Point setting
            ;FragThreshold=2312     ;Packet size to start fragmenting
            ;RTSThreshold=2312      ;Packet size to start sending RTS/CTS
            ;DataRate1=0x02         ;(1)   Mbps supported data bit rate
            ;DataRate2=0x04         ;(2)   Mbps supported data bit rate
            ;DataRate3=0x0B         ;(5.5) Mbps supported data bit rate
            ;DataRate4=0x16         ;(11)  Mbps supported data bit rate
            ;RefreshInterval=10000  ;Inactivity time to check association
            ;PowerSaveMode="CAM"    ;Constant Awake Mode
            ;MaxPowerSave="OFF"     ;Maximum power save mode
            NodeName="CiscoPC"      ;Descriptive station name
            AuthType="WEPOPEN"      ;WEP with open authentication
            ;The adapter needs 32 16-bit I/O ports, and 1 non-sharable IRQ.
            ;The following lines should be uncommented and the appropriate
            ;values set in the following scenarios:
            ; 1) PCMCIA mode: Override the I/O port base and/or IRQ
            ;                 assigned by PCMCIA card services.
            ; 2) PCMCIA mode: PCMCIA card services is not being used.
            ; 3) ISA mode: Override the I/O port base and/or IRQ assigned
            ;              by Plug and Play.
            ; 4) ISA mode: Non-Plug and Play operation.
            ;If the PCMCIA interface is being used without PCMCIA card services,
            ;uncomment the following lines and set the appropriate values.
            ;If the PCMCIA interface is not being used, set the appropriate
            ;value of "ISA" or "PCI".
  3. Boot the computer to load the above config.sys file.

  4. Issue this command:

    a:>wepdos -365 -tx1 12345678901234567890123456
    setting key 1 to 12345678901234567890123456
    setting transmit key index to 1
  5. Issue this command:

    a:>cscpkt 0x65
