LAVA does not provide drivers or support for UNIX. SCO UNIX has a command called mkdev serial that can install the port in UNIX. Consult the documentation for your version of UNIX to see if this is the correct command for you and the appropriate switches.

LAVA PCI cards do not install in Win2000 using a setup utility. They install when New Hardware is found at boot up of Windows. Windows searches your hard and floppy drives for an .inf file that includes the setup information for our card. This is a plain text file that contains the setup information for our card. Sometimes, it does not find this file so it is necessary to have our card reinstall.

The following procedure will reinstall our card:

1) Right Click on My Computer from the desktop and enter Properties and then Device Manager. Enter the section called Other Devices or Unknown Devices.

2) Remove the reference to either PCI card or PCI Serial Controller or PCI parallel controller by right-clicking on it and entering Uninstall.

3) Shut down your computer normally and ensure that our card is seated properly in the PCI slot.

4) Upon entering Windows, when New Hardware is found direct it to the LAVA Win2000 .inf file.

5) Let Windows search for our installation file and reinstall our card correctly.

WINDOWS 2000 FEATURES

In Windows 95/98/Me we provide a utility for redirecting the COM port assignment that Windows assigns our ports. This utility is not necessary in later versions of Windows. The following is the procedure to redirect our port in Windows 2000.

1) Go to Device Manager by right-clicking on My Computer from the Desktop and entering Properties.

2) Open up Ports (COM & LPT) by clicking the + sign to the left.

3) Double-click the port you wish to redirect and enter the Port Settings Tab.

4) Click the Advanced Button.

5) In the Window that appears you can redirect the port assignment.

SPECIAL WINDOWS 2000 FEATURE

Parallel Port LPT assignments can be redirected. Currently the choice for redirection is LPT1 LPT2 or LPT3.

CLEANING UP OUR INF FILE

If you are updating the .inf file from a previous version of this file it is necessary to remove the old version. You must go to the Windows\inf folder. If you don’t see the inf folder then your folder options are set to hide that folder. To see that folder go to View|Folder Options|View

In there make sure that the show all files option is set. Our .inf file is found under the name oemX.inf, where X is some integer. You must edit using notepad.exe each oemX.inf file and look for a reference to LAVA. If there is a reference to LAVA then remove that file. Also, remove the associated oemX.pnf that is located here as well.

Question:

I have upgraded my system to a newer version of Windows. I left my LAVA card in the system during the upgrade. Now in Device Manager my card is showing up in Other Devices as PCI Parallel Card or PCI Serial Card. The peripheral attached to it (modem, printer, Zip drive) won’t work. What do I do now?

Answer:

During the installation of the upgrade, Windows was looking for the drivers on the Windows upgrade CD. The card’s drivers are not located on the CD so the installation routine couldn’t install the card properly. The following procedure will reinstall the card properly:

1) Go to Device Manager by right-clicking on My Computer from the Desktop and entering Properties. Then click the Device Manager tab.

2) In Device Manager remove the PCI Parallel Card or PCI Serial Card with the exclamation (!) mark by clicking it and hitting delete on the keyboard.

3) Close all open windows and reboot the system by using Start|Restart.

4) Upon booting into Windows the New Hardware Found wizard will appear. Direct this wizard to the LAVA Installation disk, following the procedure described in the LAVA Installation manual for installing the card in Windows.

Question:

I have installed my LAVA card that has jumpers into my operating system correctly. However, when I try to use the card the OS reports that the card is not functioning properly. What should I do?

Answer:

The answer to this question applies to all LAVA cards that have IRQ jumper settings. To correct this situation it is necessary to make some BIOS setting changes. The following description applies to an Award BIOS version 4.51 PG. Consult your motherboard manual to find equivalent setting changes and how to enter your BIOS setup.

Enter PNP CONFIGURATION SETUP.

Change RESOURCES CONTROLLED BY from AUTO to MANUAL.

Scroll down to the IRQ(s) assigned to our card and change that IRQ from PCI/ISA PnP to Legacy ISA.

Installation

On install during the bootup process, Linux detects the RS422-550 and sets the configuration for ttyS2 and ttyS3. To verify proper installation you must remember the I/O range (see table below) and IRQ each serial port was jumpered to.

ttyS0 = 0×03f8; irq = 4

ttyS1 = 0×02f8; irq = 3

ttyS2 = 0×03e8; irq = 4

ttyS3 = 0×02e8; irq = 3

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

setserial -a /dev/ttyS2

Note: ttyS2 refers to Com3. This setting may change depending on how the jumpers are configured on the card.

If the card is correctly configured in Linux you will see the following information:

/dev/tty2, Line 2, UART 16550A, Port: 0×03e8, IRQ: 4

Baud_base: 115200, close_delay: 256, divisor: 0

closing_wait: 15360

Flags: spd_normal skip_test

Your port and IRQ should conform to the jumper settings on the card.

If you find that the information displayed does not match the above (port and IRQ should match your jumper settings), 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/ttyS2 port 0×03e8 irq 4 uart 16550a baud_base 115200 ^fourport

setserial /dev/ttyS3 port 0×02e8 irq 3 uart 16550a baud_base 115200 ^fourport

Your port/IRQ may be different depending on the jumper settings on the card. Be sure to save the added changes. On reboot all of the ports should be operational.

INSTRUCTIONS ON SETTING BIOS FOR JUMPERED CARDS

Question:

I have installed my LAVA card that has jumpers into my
operating system correctly. However, when I try to use
the card the OS reports that the card is not functioning
properly. What should I do?

Answer:

The answer to this question applies to all LAVA cards
that have IRQ jumper settings. To correct this situation
it is necessary to make some BIOS setting changes. The
following description applies to an Award BIOS
version 4.51 PG. Consult your motherboard manual to find
equivalent setting changes and how to enter your BIOS setup.

Enter PNP CONFIGURATION SETUP.

Change RESOURCES CONTROLLED BY from AUTO to MANUAL.

Scroll down to the IRQ(s) assigned to our card and change
that IRQ from PCI/ISA PnP to Legacy ISA.

To properly install an ISA serial port, you need a free IRQ and I/O address on your computer for the LAVA card to use.

Shut down your computer

To check for free resources, shut down your computer. If the card is in your computer, remove it now. Next, restart your computer.

Set the I/O address

Once your computer has restarted without the card, go into Windows Device Manager, and select “Ports”. Choose a COM port, select “Properties”, and write down the I/O address.

After you’ve done this for all COM ports, set the addressing jumpers on your card to an address NOT ALREADY USED by Windows. For example, if you found that COM1 had an address of 03F8, you would configure your card to use the next available address of 02F8.

Set the IRQ

Next, return to Device Manager, select “View”, and choose “Resources by type”. This will give you a list of all IRQs that are currently being used by the computer. Write down all numbers from 1 to 15 that DO NOT appear in that list. Any IRQ that you have written down can be used as a free IRQ for the port you are installing.

Set IRQ jumper on the card to one of the free IRQs in your computer. Once you’ve done this, you are ready to shut down the computer, and install the card.

Restart your computer

Once the card is installed in the computer, reboot your system. After the Operating System is fully loaded, go to Control Panel, and select “Printers and Other Hardware”. In that Window you should see an option to “Add Hardware”. Windows will then search for hardware, and ask you if the hardware is currently connected to the computer. Select “Yes, I have already connected the hardware”. You will then see a Window where you are prompted to select the type of device you have installed. Select “Add a New Hardware Device”, which should appear as the last entry on the list.

Windows will then prompt you to either automatically or manually install the device. At this point select “Install the hardware that I manually select from a list”. You should then be able to select “Ports”, then choose “Standard” and “Communications port”.

Prior to finishing the installation, select “View or Change Resources for this Hardware (Advanced)”. This option will allow you to configure Windows to recognize the resources you have selected for your card. Once you select this option, the “Add New Hardware Property” window should appear. Now select “Set Configuration Manually.” Under “Settings Based On”, choose “Basic Configuration 0008″. This option will allow you to specify the settings for your card. You should now be able to double-click the I/O range and the IRQ and enter the resources to reflect how you set the jumpers on your card.

Once this is done, select Finish, and restart your computer.

Check your settings

Once your computer has restarted, you should go back to Device Manager, and ensure that the resources the computer has given to the card match what you specified earlier. At this point, you may find your port has defaulted to become something other than what you specified. If you wish to change this setting, double-click the port listing and go to the “Port-Settings” tab. Choose “Advanced”.

Change the COM number to what you desire.

Once these changes are made, you should be able to use your ISA serial port.

These instructions are framed for the LAVA DSerial-550, but can be used for any jumpered LAVA card.

1) Check for available resources. Enter Device Manager By RIGHT clicking on My Computer from the desktop going to properties and then clicking the Device Manager Tab.

Double-click computer in Device Manager.

Find a number missing in here between 0 and 15. If 9 is missing then set the IRQ jumper to 2. If all the IRQs are being used then you must disable a device to free up an interrupt for our card.

In Device Manager open up ports COM and LPT. Record which COMs are in there. In Device Manager open up Modems. Double-click your internal modem (if you have one). Go to the Modem tab. Record the COM it is using. Set the COM jumper NOT to what you have currently recorded.

I.e. if you have recorded COM1 COM2 COM3 jumper our card for COM4.

2) Shut down your computer and place our card back in the slot.

3) Boot into the BIOS setup. Reserve the IRQ in the BIOS setup.

These instructions apply to all LAVA Cards that have IRQ jumper settings. The following steps apply to an Award BIOS version 4.51 PG. Consult your motherboard manual to find equivalent settings and how to enter your BIOS setup.

Enter PNP CONFIGURATION SETUP. Change RESOURCES CONTROLLED BY from AUTO to MANUAL. Scroll down to the IRQ assigned to our card and change that IRQ from PCI/ISA PnP to Legacy ISA. Save Settings and exit.

4) Boot back into Windows.

5) Run Add New Hardware and let it detect our card.

6) Go to device manager and double click the new COM port. Go to Resources and make sure that the interrupt request matches what you have set our card to.

7) Repeat Steps 1)-6) for the second serial port.
