Utility File Descriptions:

  o2init.sys, o2init.com, o2init.doc:
    These files are used to initialize various registers on the O2Micro cardbus
    controller from a script (.dat) file.  See o2init.doc for help.

  preg.exe:
    A DOS utility to view/edit PCI configuration space of PCI devices.

  o2sw.exe:
    A Windows utility to control O2Micro Zoom Video features.

  o2.exe:
    A DOS utility to view/edit PCMCIA ExCA registers.

  o2acpi.exe:
    A Windows utility to enable/set ACPI modes of an ACPI CardBus controller.



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 init the controller at boot time.

  To install:
    1 Copy the software to the hard disk
        cd c:\
        mkdir o2
        copy a:\util\*.* c:\o2\.
    2 Edit config.sys, enter as the first line:
        device=c:\o2\o2init.sys c:\o2\legacy.dat
        This will program the cardbus controller look like standard PCIC at
        ports 3E0, and 3E1.
    3 shut down, install O2Micro Cardbus card
    4 power up, do 'Control Panel, Add Hardware, Pcmcia, PCIC'
    5 click on 'Control Panel, Pcmcia' to run pcmcia wizard for 32 bit enable
    6 restart 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.


  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.
    1 Copy the software to the hard disk
        cd c:\
        mkdir o2
        copy a:\util\*.* c:\o2\.
    2 Edit config.sys, enter as the first line:
        device=c:\o2\o2init.sys c:\o2\legacy.dat
        This will program the cardbus controller look like standard PCIC
        at ports 3E0 and 3E1.
    3 shut down, install O2Micro Cardbus card.
    4 power up and install the 3rd party 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.
