O2Micro Cardbus Controller Software Installation
------------------------------------------------

  Win95 (release 1):

  Win 95 supports PCMCIA/PCIC controllers, but does not directly support
  CardBus controllers.  A newer bios will initialize a CardBus chip
  as a Legacy mode PCIC controller, but bioses that do this are still
  rare.  If your bios does not initialize the CardBus controller to
  Legacy mode, use o2init.sys to initialize the controller at boot time.

  To install:
    1. Copy the software to the hard disk:
         cd c:\
         mkdir c:\o2
         copy a:\util\*.* c:\o2\. /v

    2. Edit "Config.sys": (add the following line to beginning of file)
         device=c:\o2\o2init.sys c:\o2\OZ68????.dat
         Where: ???? is the appropriate file for the device being installed

    3. Shutdown Windows and Power-off the system.
    4. Install the O2Micro Cardbus card and reboot Windows.
    5. In "Control Panel" do "Add Hardware", "Pcmcia", "PCIC", and exit.
    6. In "Control Panel" run "Pcmcia" to enable 32 bit support.
    7. Reboot Windows to load the new PCIC driver.


  Windows95 OSR2 and Windows98:

  Install the O2Micro board and run O2Setup.exe.  This will copy
  some files and add registry keys.  You will have to reboot to load
  the new drivers.

  To install:
    1. Copy the software to the hard disk:
         cd c:\
         mkdir c:\o2
         xcopy a:\*.* c:\o2\. /s/e/v

    2. Edit "Config.sys": (add the following line to beginning of file)
         device=c:\o2\util\o2init.sys c:\o2\util\OZ68????.dat
         Where: ???? is the appropriate file for the device being installed

    3. Shutdown Windows and Power-off the system.
    4. Install the O2Micro Cardbus card and reboot Windows.
    5. Run O2Micro Setup Program (C:\O2\O2SETUP.EXE).
    6. Reboot Windows to redetect new hardware.


  Windows3.1/3.11 and MS-Dos:

  Win 3.1 and MSDos do not include any drivers for Cardbus or Pcmcia.  You
  will need to install third party drivers from Phoenix, SystemSoft, Award,
  or others to test the O2Micro controller.  You need to put the controller
  in the Legacy mode before installing the third party software.

  To install:
    1. Copy the software to the hard disk:
         cd c:\
         mkdir c:\o2
         copy a:\util\*.* c:\o2\. /v

    2. Edit "Config.sys": (add the following line to beginning of file)
         device=c:\o2\o2init.sys c:\o2\OZ68????.dat
         Where: ???? is the appropriate file for the device being installed

    3. Power-off the system.
    4. Install the O2Micro Cardbus card and reboot Windows.
    5. Load 3rd party PCMCIA software.


Debugging an O2Micro Cardbus controller:

    A cardbus controller is a PCI device with standard PCI registers.  The
  cardbus controller registers are memory mapped at the location set in PCI
  register 10h.  Under Win95, the device manager properties can be examined
  to find that memory location.  However, Win95 maps this memory to some
  other address.  This makes debugging the cardbus controller a bit tricky.

    The easiest way to debug is to use SoftIce for Win95.  To find the
  cardbus registers in SoftIce, use the 'phys' command to translate the
  memory address to the physical memory address.  For example 'phys C8000'
  gives an address like C1297000.  To dump the registers do 'd #30:c1297000'.
  Cardbus registers are mapped into this memory block at offset 0, and the
  pcmcia/ExCA registers are mapped into this memory at offset 800h.

    The O2Micro Cardbus Controller is a single chip with 2 PCI devices
  (functions).  Windows 95 views the chip as 2 separate PCI devices so there
  are two O2Micro entries in the Device Manager display, and there are two
  blocks of memory allocated, one for each PCI function of the controller.
  You find the memory mapped registers for each function the same way,
  but Win95 maps their addresses independently and they might not be in
  contiguous locations.  Take care when translating the memory addresses,
  and also make sure the the memory you are viewing is correct for the
  slot you are testing.

How To Update Drivers Manually

After your driver has been downloaded, follow these simple steps to install it.

  • Expand the archive file (if the download file is in zip or rar format).

  • If the expanded file has an .exe extension, double click it and follow the installation instructions.

  • Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.

  • Find the device and model you want to update in the device list.

  • Double-click on it to open the Properties dialog box.

  • From the Properties dialog box, select the Driver tab.

  • Click the Update Driver button, then follow the instructions.

Very important: You must reboot your system to ensure that any driver updates have taken effect.
