PCI Modem - does not recognize

Hi All,

I'm using WIN 98 SE with a P4 processor that includes a PCI Creative Flash 56 modem.

When initially installed, the modem worked fine. Then, I installed a USB 2.0 PCI card and now the modem can no longer be detected. I deleted the modem and reinstalled and device manager says it is working but then says can't find port in registry. No matter what I do, I can't get this detected by Win anymore and 'diagnostics' in Control Panal, Modem shows nothing. I was using the modem to send faxes and now nothing will recognize that a modem even exits.

Any suggestions would be greatly apprecicated.

Thanks,
Len
 
I would say try uninstalling the usb 2.0 PCI card and / or possibly try swapping the modem to a different PCI slot.
 
As fishmonger12 suggested, it could be an IRQ conflict. Start by checking the IRQ's for the modem and USB port in Device Manager to see if they overlap. If so:

1. Delete the modem from Device Manager and uninstall any software, drivers, etc.

2. Power down, and plug the modem into a different PCI slot.

3. Reboot, and let the system detect the modem, again. Follow the installation instructions for your modem. Some brands will install automatically. Others tell you to skip the Windows detection and use their software.

4. Check the IRQ's in Device Manage, again, to see if the problem is resolved.

Good luck. 🙂
 
The USB 2.0 PCI card is another problem.

It was recognized after I installed the drivers, but it subsequently disappeared.

The VIA chipset for USB 2.0 has caused plenty of problems and that is why I installed the PCI card so I could really have USB 2.0. The VIA was giving me USB 1.

Now, I have USB 2.0 for the VIA sockets but nothing for the PCI card sockets and no modem also.

Don't know what to do now.

The odd thing is that there is no IRQ showing for the modem. Just a selection of com ports. Previously, when the modem was working, it showed IRQ 5 and no conflicts which was fine.

I tried different com ports and even disabled com1 and used com2 for the modem but that didn't work either. When the modem had worked, it showed com3 and irq 5. Now, com3 doesn't even show up. The board has 2 com ports and I had wanted the modem to be com3.

Certainly a mystery to me.

I know I should upgrade to XP, but I would rather stick with 98 SE as I do alot of DOS work and want to keep fat32.

That could be part of your problem. Did you disable USB in your BIOS? If not, that could cause a conflict. The fact that you're using a PCI card also suggests a possible conflict with your modem.

You didn't tell us what your motherboard is, but before you go much further, check the manufacturer's site for a possible BIOS or USB driver update. Also, check VIA's site for newer drivers. Then, uninstall the modem and the PCI USB card, and try again, starting with the onboard USB driver.

FWIW, I'm running Win 98 SE on a VIA chipset board with onboard USB 2.0, and everything works well.
 
Hi, Sometimes modems can be a pain to reinstall in Win98 and probably all Windows. Check the modem makers install disk and The install/uninstall programs list for an uninstall for the modem. The makers uninstall will usually get you going on the reinstall. I have at times had to completely remove all mention of the specific modem from the machine including the Registry. Jim
 
Have you tried the win98se rollup at http://exuberant.ms11.net/98sesp.html

I'm using it with a PCI USB 2 card, win98se, serial modem, usb card reader, scanner, printer on a Athlon 700 in a FIC sd-11 board (AMD/VIA hybrid)

It is supposed to include a lot of system, usb , and security updates.

That's your problem, I think. If the modem was installed as a PnP modem, then it automatically aquires a set of hardware resources as well. If the modem is installed as a non-PnP modem, then it references a set of "ports", and then you need to have a seperate "Serial Port" or "Comm Port" device, which then itself has the hardware resources assigned. I would completely un-install the modem, including the .INF and .PNF file for it that gets installed into the \WINDOWS\INF or \WINDOWS\INF\OTHER directory, and then remove the card physically from the machine (after powering off, of course), and then select "Clear ESCD" or "Clear PnP Data" in the BIOS, reboot, shut down, re-install the modem physically, and then follow the normal fresh installation instructions.

Hopefully, it will then get re-installed, as a PnP modem, using whatever the currently-allocated/available IRQ is. (As installing that USB 2.0 card probably changed it out from under the modem before.)

Another thing to try, would be to reboot into Safe Mode, and then delete any and all modem and port device entries, and then follow the above procedure.
 
Thanks for those great suggestions.

I downloaded the WIN 98 SE service pack which I'll try after I do the ESCD.

I'll post the results after that.

Hi again, I ran across some info the other day about a program called ASD.exe. It comes with 98SE and always loads when you set up Win. In some circumstances Windows decides that it doesn't want to try to load a device ever again. It's name is stored by ASD. RUN ASD and it will tell you if your modem is on the hit list. If it is, it will let you remove it. I remember using it a long time ago and it did work. Worth a try. Jim
 
Thanks, I'll try it.
Nothing else has worked so far. That ESCD in the CMOS didn't do a thing.

I'll keep trying and see what happens.

Len
 
I tried the ASD and it said ".. no critical failures..."

I don't know what to try next, but I'll keep working on it.

What I really can't understand is why the system tries to install an ISA type modem, when it is a PCI in a PCI slot.
