   ===================================================
   This release of the Xircom CreditCard Ethernet Adapter IIps has 
   the following characteristics:

   -Card and Socket Services is a software specification defined by 
    the PCMCIA organization. Its purpose is to serve as an 
    intermediary between the network device driver and the system 
    resources required by the PCMCIA Adapter.

   -Variable interrupts, 3 to 15, default interrupt 5.

   -Variable IO window, 16 bytes needed for memory mapped mode and 32 
    bytes needed for IO mode, with default base at 320h.

   -Requires an 4Kbyte memory window on an 4Kbyte boundary, within 
    segment A000h to EF00h, default is D200h.  
  
    *** NOTE:  WE DO NOT SUPPORT THE D000-D0FF SEGMENT.  
	       SEE SECTION 4 UNDER MEMORY RANGE NOTES.

   -Keyword support to disable link integrity.
   
   -Full Duplex capabilities increases bandwidth to 20Mbps.

   -Advanced Look-Ahead Pipelining drivers for superior adapter 
    performance.

   -Windows-based installation program that automatically configures 
    PC and NOS setup.

   
2) RELEASE NOTES/KNOWN LIMITATIONS

   Release Notes
   -------------

   - This release adds increased functionality with Cirrus Logic
   chipsets.  
   - This release adds increased Ricoh chipset support.
   - NDIS drivers now install properly under OS/2
   - NDIS & ODI 16bit drivers now incorporate auto resource scan which 
   assigns resources on driver load.
   - It resolves exception errors subsequent to running DOS
   edit in DOS box under windows.  
   -- It also corrects the cfg.ini for NDIS3 driver under Windows 
   for Workgroups 3.11.


   Known Limitations   
   -----------------
   
   -The default memory exclusion on some laptops is not large enough 
    for the Installation Program to successfully complete.  Xircom 
    recommends reviewing the CONFIG.SYS and verifying the EMM386.EXE 
    entry has a memory exclusion of at least 16K.
    .   examples:  
    .   DEVICE=C:\DOS\EMM386.EXE X=C800-CBFF
    .   or
    .   DEVICE=C:\DOS\EMM386.EXE X=D000-D3FF
  

   -Hotswapping and Suspend/Resume are not supported using the NDIS 3.0 
    driver for Windows for Workgroups.  

   -Card and Socket Services should be enabled when using the Xircom
    Installation Program on systems having the Databook chipset.

   -When installing LAN Workplace for DOS, use the keyword MODE IO
    in the NET.CFG.

   -When installing under Windows 95 certain conflicts may exist between
    Tranxit Software by Puma Technologies and this driver.  If you 
    require a work around please use our MiniPort Driver which can be
    found on the Xircom BBS and Web Site under patches section.

   -Windows NT Advanced Power Management is not supported by this
    Driver.  If you require this feature please use our MiniPort Driver
    which can be found on the Xircom BBS and Web Site under the patches
    section.

4) SPECIAL CONFIGURATION NOTES
   ===========================

   Memory Managers
   ---------------
   When using a memory manager, be certain to exclude the memory
   range being used by the CreditCard Ethernet Adapter IIps Software.
   An 4K range will need to be excluded within C000 to EF00.

   .   example:   device=c:\dos\himem.sys
   .              device=c:\dos\emm386.exe x=D200-D2FF

   This example excludes 4K starting at the D200 segment for use by 
   the Xircom Performance Series Software in a default configuration.  
   If the Xircom CreditCard Ethernet Adapter IIps Software is
   configured for a memory address different from the default,
   be certain to exclude the appropriate memory address range.

   Memory Range Notes
   ------------------
   -The Xircom CreditCard Ethernet Adapter IIps Software does not 
    support the memory range D000-D0FF.

   -On some machines D600-D6FF is not supported.  

   -The Xircom Performance Series Software supports only 16byte IO
    addresses (example: 240, 250, 260, 270 ... 340, 350, 360).  

   Full Duplex Notes
   -----------------
   To utilize full duplex capabilities, your network must have full duplex 
   hardware in place and enabled.  If your network connection does not 
   have full duplex and you use the FULLDUPLEX option, your network will
   become unusable due to excessive collisions.


5) MACHINE SPECIFIC NOTES
   ======================

   Gateway ColorBook DX/75
   -----------------------
   The Gateway Colorbook DX/75 must use a MEMWAITSTATES = 1 keyword in
   either NET.CFG or PROTOCOL.INI files in order to function.

   IBM Thinkpad 360
   ----------------
   The IBM Thinkpad 360 must use a MEMWAITSTATES = 1 keyword in either
   NET.CFG or PROTOCOL.INI files in order to function.

   NEC Versa 2000C, 4000C and 550 Models   
   -------------------------------------

   Under Windows for Workgroups, the keyword NOEARLYTX must be added to 
   the PROTOCOL.INI.

   Toshiba 1900, 1950CS
   --------------------
   This model will not initialize properly at IO port 300, use another 
   IO port, such as 320.

   

6) INSTALLATION PROGRAM
   ====================
   
   DOS 6.x STARTUP MENU NOTES   
   --------------------------
   Xircom's CreditCard Ethernet Adapter IIps requires a 4K range of 
   your PC's memory.  If you are using a memory manager such as EMM386
   or QEMM, the installation program requires an 4K memory range.

   PREVIOUS INSTALLATIONS
   ----------------------
   If you have existing Novell network drivers loaded in your 
   CONFIG.SYS or AUTOEXEC.BAT, the Xircom Installation Program will 
   attempt to remark (REM) the entries since they could conflict with 
   the Xircom installation. If the installation program cannot remark 
   these entries, you will be prompted to REM or remark them 
   yourself. After you remark or REM out the existing driver entries, 
   re-run the Xircom Installation Program.

   NETWARE 4.x INSTALLATION NOTES
   ------------------------------
   The Novell NetWare 4.x Client Install program does not support
   loading of Xircom's CXCFG.EXE file, which is a file required for 
   configuration of some PCMCIA slots.  If you complete the NetWare 
   4.x installation and experience problems attaching to your 
   network, follow these instructions:

   Using a DOS editor (such as EDIT), edit your STARTNET.BAT file 
   and add the line CXCFG before the lines LSL and XPSODI.


7) XIRCOM TECHNICAL SUPPORT
   ========================
   To obtain technical support for your Xircom product, please call or send 
   a facsimile to the appropriate number listed below.
   
   Access the Xircom TechLine quick-search database of problem 
   solutions at up to 14400 bps, No parity, 8 data bits, 1 stop bit (N-8-1). 
   Use ANSI for your terminal emulation (you must have ANSI.SYS loaded on 
   your system to use the Xircom KnowledgeLine).
   
   Access the Xircom INFOSYS BBS at up to 14400 bps (28800 in the U.S.), 
   No parity, 8 data bits, 1 stop bit (N-8-1).  Use ANSI, TTY, or NONE for 
   your terminal emulation as the Xircom BBS PCs do not support DEC VT-type 
   terminal emulation.
