a) Shut down the Computer and enter your BIOS (CMOS) setup.  Ensure that Plug and Play Operating System installed is set to NO or DISABLED. 
Reserve IRQs you have chosen for jumpered cards to Legacy ISA. This will eliminate any possibility of conflicts being created with those devices. Make sure that there is an IRQ available for our card.
Do this in the following manner:
Scroll down to the IRQ assigned to our card and change that IRQ from PCI/ISA PnP to Legacy ISA to make it unavailable for our card.  If all the IRQs are made unavailable then the IOFLEX-2SP+ PCI product will not install.
The previous method applies to an Award BIOS version 4.51 PG.  Consult your motherboard manual to find similar settings changes and how to enter your BIOS setup.

NOTE: Reserving the IRQs in the BIOS is just a precautionary measure.  It eliminates the possibility of our card on an IRQ already being used by an ISA device.  ISA devices are not capable of sharing their IRQs.
However, the Plug and Play Operating System setting must be set to NO or DISABLED.  If your BIOS does not have this setting it may be that it is set to this setting 'behind the scenes'.

a) With the power off place the IOFLEX-2SP+ Parallel PCI into a PCI slot.
Ensure that the slot is not a Shared PCI/ISA slot.  Consult your mother board to verify that the slot is not a shared PCI/ISA slot
b) Power up the computer and boot into Windows NT4.0 and log on as Administrator.
c) Run the setup.exe located on the NT4.0 directory on the floppy.
d) After setup has completed and the system has rebooted verify that the IOFLEX-2SP+ has installed properly by going to Start Settings Control Panel and entering the LavaPort Control Panel Applet.

To change the address assignment for the IOFLEX-2SP+ Parallel PCI go to Start Settings Control Panel and Double Click the LavaPort Icon.
The LavaPort Control Panel Applet will appear and the Lava Parallel Port(s) will appear under the Lava Parallel Ports Tree.
The IOFLEX-2SP+ Parallel PCI allows for manual Address Assignments.  There are two manual addresses available: 0378 and 0278.
To change the address then hilite the port you wish to change and click  Properties.  In the drop down list for Base I/O Port Address you will have a choice of Default (PCI bus assigned address), 0378 or 0278.
If you are installing a printer to the IOFLEX-2SP+ Parallel PCI choose the PCI Bus assigned address.  
If you are installing a non-printer peripheral such as a scanner or external drive then choose either 0278 or 0378 . Ensure that you do not assign the IOFLEX-2SP+ Parallel PCI to an address used by your onboard parallel port. To find out where your OnBoard Parallel Port is installed go to Start - Programs - Adminstrative Tools - Windows NT Diagnostics.  Enter the Resources Tab and then click the Devices button to the bottom right.  In the list of Devices that appear, double click the ParPort device.  The IO address associated with the ISA bus is the OnBoard Parallel Port Address.


The IOFLEX-2SP+ drivers will show messages in the Event Viewer regarding success or failure.  If you are having trouble with the IOFLEX-2SP+ go to Start - Programs - Administrative Tools - Event Viewer.  Ensure that the System Log is enabled from the Log Menu.  Write down any messages reported by the following services:
Consult KSI's FAQs on our Web Site ( for relevant solutions.  Or send email to
Use of the LavaPort Control Applet:

1. The LavaPort Control Applet was written in a "Plug and Play" manner.  It will attempt to install your card and attempt to show you any conflicts.
2. Information from LavaPort Control Applet installation is written to the System Log.  Please refer here for more detailed information.
3. "KSI strongly recommends the use of the LavaPort Control Applet for use with your IOFLEX-2SP+ PCI product, for both installation and to make user-defined settings changes."
4. By clicking in Control Panel - LavaPorts you will find information  on your IOFLEX-2SP+ PCI product.  Double click it and you will see one of these possibilities:
* Just the icon, indicates NO CONFLICTS.
* Red "X" through the icon, indicates the hardware has been disabled.  This can happen if you override the standard Com settings.  Accessing the System Log will indicate the overlap in the Com Registers.
* Blue "!" exclamation point, indicates a System Conflict.
* Yellow "?" question mark, indicates a card not enumerated by the System (the conflict is unresolved).
