Uninstalling the drivers and applet in Windows NT4.0 is generally not necessary. They will remain dormant until the time comes that you install another LAVA PCI card. The following procedure is provided in case that you do need to uninstall these drivers.

A) Removing Files

Remove the following files from your hard drive:

detlava.sys and seriallava.sys from winnt\system32\drivers

lavaport.cpl from winnt\system32\

B) Cleaning Registry

NOTE: To run the registry editor go to Start|Run, type “regedt32″ and then click OK.

Go to:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Enum\Root

1) Highlight the LEGACY_SERIALLAVA

2) Go to the Security menu and click the Permissions tab.

3) Check the box for Replace permissions on existing subkeys.

4) Change type of access from Read to Full Control.

5) Highlight the LEGACY_DETECTLAVA

6) Go to the Security menu and click the Permissions tab.

7) Check the box for Replace permissions on existing subkeys.

8) Change type of access from Read to Full Control.

9) Remove the LEGACY_DETECTLAVA and LEGACY_SERIALLAVA keys.

10) Go to:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services

11) Remove the DetectLava and SerialLava keys. You do not have to change security privileges for these folders because they are already set at Full Control.

Question

I have installed my LAVA PCI serial card and then my Modem was installed by Plug and Play. I then looked in Control Panel|Modems and tried to click the properties, but nothing happened.

Answer

When a modem installs in the PnP (Plug and play) manner (at boot-up), the modem installs in Control Panel|Modems but when you click the properties button nothing happens. This is a known problem for which we are endeavouring to find a solution. The solution is:

Go to regedit by entering regedit from Start|Run.

Open up

HKEY_LOCAL_MACHINE System CurrentControlSet Services Class Modem.

Inside there may be several numbers, i.e. 0000,0001,00002….

Open up each of those and look for DriverDesc such as: 3ComImpactIQ or the name of the modem that you are using.

That is the folder that will need the string added to it.

To add the string the following method is followed:

Go to the Edit menu then New and String Value.

Change the name of that new string to the following exactly: AttachedTo

Change the value to COMx where x is the com port number to which the modem is attached. (i.e. COM3) by double-clicking it.

Question

I am trying to install the LAVA PCI card in an OS other than DOS, Win3.11, Win95/98/Me, NT4.0, or Windows 2000. I have commands or a utility that can configure my port. However, I have no way of knowing how the PCI bus on my system has configured the card. What can I do?

Answer

LAVA provides a utility that reports the I/O address and IRQ assigned by the PCI bus on your system. This utility MUST be run from DOS level.

This utility can be run from a DOS boot disk to report the I/O address range and IRQ that the PCI bus on your system has configured our card to.

Use this utility if you wish to configure a parallel port in an OS other than DOS, Win3.11, Win95/98/Me, NT4.0, or Windows 2000. For example SCO UNIX, Linux… i.e. using the makedev parallel command. Consult the Man Pages or documentation for the OS for the appropriate commands.

Create a DOS boot disk in DOS compatible system (not NT4.0) with the following command:

format a: /s

Copy Lavaconf.exe to that diskette.

(Can be downloaded from the Utilities portion of our web site for your PCI card www.lavalink.com or can be found in the Win3.11 directory on the LAVA Installation and Utilities disk).

Restart the machine that you wish to install the LAVA Parallel-PCI in and boot from that boot disk you created.

Run the Lavaconf.exe program.

If this software reports an address that ends with 0, then the ending address will end in 7.

If this software reports an address that ends with 8, then the ending address will end in F.

i.e. Lavaconf reports:

10F0

then in the OS put 10F0-10F7 for the Input/Output Range.

i.e. Lavaconf reports:

10F8

then in the OS put 10F8-10FF for the Input/Output Range.

Installation

With the power turned off, insert the DSerial-PCI card into any free PCI slot in your PC. Make sure the card is well seated. Turn your PC on and start QNX 6.

NOTE: If you are using an AGP video card you may find that QNX will not boot with the card in the PCI slot immediately following the AGP slot. Simply place the card in the second slot to alleviate this problem.

QNX will automatically detect the presence of the DSerial-PCI card and create two devices in the folder /etc/dev/ called Ser[x] and Ser[x+1] (where x is the next available serial device number determined by QNX while enumerating the PCI bus at boot-up).

NOTE: QNX will always enumerate Port A before Port B (i.e. Ser[x] will always refer to Port A and Ser[x+1] will always refer to Port B).

To verify that the card has been installed you may check in either the /etc/dev/ folder, or in QNX’s System Information (Launch>Utilities>System Information). Within the System Information listing you will find a process named “devc-ser8250″. By selecting this process you will have access to several different information tabs. Selecting the Arguments tab (Args) will provide you with the exact arguments that were passed to the devc-ser8250 process at boot-up. From here you can easily determine which port is assigned to which serial device by referring to the card?s resources.

For example, given the process command “devc-ser8250 -u1 3F8,3 -u2 2F8,4 -u3 a000,5″ we can see that Com1 and Com2 were mapped to devices Ser1 and Ser2 respectively and our serial port at a000 was mapped to device Ser3.

Card Resources

You can easily determine the physical address and IRQ resources of the card?s serial port by displaying the PCI listing “pci -v”. This command will display all the information for each of the PCI devices on the system bus. To find the IO address and IRQ of the card, simply scan through the output of this command for a section beginning with “Vendor ID = 1407h, Lava Computer MFG Inc.”, of which there should be two sections, one for each port.

NOTE: QNX will always enumerate Port A before Port B. Therefore, when reading the PCI listing from top to bottom Port A will be displayed first followed immediately by Port B.

Testing

Testing the card’s functionality can be done by using QNX’s own terminal program, Qtalk, and a loopback connector. To test a port, attach the loopback connector and open up a Qtalk session by executing the command “qtalk -m /dev/ser3 -b 115200,8,n,1″ on the port. While the loopback connector is attached any characters entered in Qtalk should be echoed back to the screen. Removing the loopback connector should prevent character echoing from occurring.

Troubleshooting

If for some reason the card was not picked up by QNX at boot-up, but the card is displayed in the PCI listing, you may manually add the port by using the devc-ser8250 command.

Example: Say we have two serial ports residing at physical addresses=a000 and a400, sharing IRQ=5 and neither of which is allocated a serial device in the /etc/dev/ folder. If we have determined that Ser1 and Ser2 already exist in the /etc/dev/ folder (this is done by inspecting the folder /etc/dev/ for all serial devices), we can add two new serial devices by running the command:

devc-ser8250 -u3 a000,5 -u4 a400,5

This is a very simple example of adding two new serial devices by using the devc-ser8250 command. Full documentation of all the options associated with this command can be found in the QNX 6 RTOS Utilities Reference Manual.

Installation

On install during the bootup process, the Linux hardware discovery utility detects the DSerial-PCI correctly and installs it as ttyS4 and ttyS5. This setting will change depending on how many serial ports you have and how they are configured.

To verify proper installation you must first find out the port information (I/O range, IRQ) for each serial port. To retrieve that information type at the command line:

lspci -v

You will then see two separate entries for a “Serial Controller: Lava Computer MFG”. Below each will be a IRQ number and an I/O port. Write down that information for all ports (for example, IRQ 12, e400, IRQ 12, e800).

First you must verify that the card was installed correctly. To do this at the command line type:

setserial -a /dev/ttyS4

Note: ttyS4 is the first default PCI serial port. This setting may change depending on how many serial ports you have.

If the card was correctly configured by Linux you will see the following information:

/dev/tty4, Line 4, UART 16550A, Port: 0xe400, IRQ: 12

Baud_base: 115200, close_delay: 256, divisor: 0

closing_wait: 15360

Flags: spd_normal skip_test

Your port and IRQ should match the information collected earlier.

If you find that the information displayed does not match the above (port and IRQ should match your information), then carry on to the next step below. If the data is correct then the installation is complete.

To set the serial port to the correct settings, edit the file:

/etc/rc.d/rc.local

Add the following lines at the end of the file:

setserial /dev/ttyS4 port 0xe400 irq 12 uart 16550a baud_base 115200 ^fourport

setserial /dev/ttyS5 port 0xe800 irq 12 uart 16550a baud_base 115200 ^fourport

The example above uses the information gained from the lspci -v command. The details of your information may be different. Be sure to save the added changes. On reboot all of the ports should be operational.

I am running an IBM 300 GL computer that has a LAVA PCI card in it. When I boot up I get a Parity error! Is there a BIOS setup setting that I can modify to get the system to boot normally?

This problem occurs on certain IBM machines. There is a BIOS setting that can ensure that the system boots up normally while the card is in the system.

In your BIOS setup go to: Advanced Setup | PCI control and set PCI Parity Control to Disabled.

On some IBM and COMPAQ machines some BIOS (CMOS) setup settings could cause the machine not to boot up completely.

Change BIOS settings without the card in the system.

NOTE: Not all systems have all these settings. Included are a few of the settings that have caused problems on various IBM and COMPAQ machines. Consult your IBM or COMPAQ manual for instructions on how to enter the setup and where to find these settings.

Enter the BIOS and go to Advanced and then BUS Options.

Verify that:

Plug and Play OS Installed is set to NO or DISABLED.

PCI Parity is set to Disabled.

PCI Bus Mastering is set to Enabled.

PCI Adapter Reset is set to Disabled.

PCI Adapter Reset on Warm Boot.
