Plug and Play Problems

could it be your bios is set to PNP No?, if it is , change it to yes.
you can also try another PCI slot.

Hi,

You say:-
I have tried two different modems and the same problem occurs.
Then problem is with port or as nobus said you have not enabled PNP Manager in BIOS.

They you say: -
I connect the modem to the PCI Port and boot into windows.  No new devices have been found.  I go to control panel and search for new hardware, still nothing.  

It means there is no problem with Windows PnP Manager...it has been started when you clicked on Add/Remove Hardware. When Add/Remove Hardware wizard is started it sees the status of Plug and Play service from services.msc snap-in. If the status is Automatic and service is not started then it forces service to start. So Windows functionality is working.

you say: -
>>>I manually install the modem drivers, they install ok.

It is just like you are installing an application. Windows OS does not know that you are installing a driver for modem because you click on a EXE or MSI files to install. So it is just like an application installation. Still no problem with OS :-)

>>>Go to modem properties and diagnotics and click more info.  Then I have an error "Modem has failed to respond. Make sure it is properly connected and turned on. If it is an internal modem or connected, verify that the interupt for the port is properly set"

Now Windows OS is correct here. Still the Windows is working properly and giving you the right error message. It can't communicate with the modem using PCI Slot.

>>>I have removed the com ports from device manager, uninstalled the modem and disabled the serial ports in bios then restarted the computer.  After detecting new hardware and enabling the serial ports in bios, still the modem is not detected.  

You should not remove COM1 ports. There is no logic to remove all those ports because ur Ports from system have been detected and working properly. Now problem is that ports can not communicate using Model Cable or Port itself.

This could be a problem of Cable connected to modem or the COM1 or COM2 port not connected properly inside the PC.

>>>I have tried going into the com port settings in device manager and changing the resource settings.  I can not change the interupt portindividually.  I also tried the modems in a XP machine, and they detected no problem.  What am I doing wrong?

Yeah,,,,Cheers...So Look for two things :-

Port connected to MotherBoard
Modem Cable

Please post back for further calrification...

Thankx

Answers to your feedback...

The Bios is set to PNP = Yes  ( I also tried installing an old ISA modem which PNP detected no problem. )
I already tried switching with the Video card PCI Slot. (Video card works in both slots, modem does not work in either slot.)

SystmProg, you stated to check the modem cable.  This is an internal modem, no cable needed. You also asked to check if the port is connected to the motherboard. Are you talking about the Serial connections?  They are both working fine, got the serial mouse to prove it :)  

I am stumped and curious.

Then you have Internal Modem Card....sorry...

If there is conflict between PCI slots and attached devices..the OS will let you know. So it is not. Do one thing :- make sure Plug and Play service is running in Services.msc snap-in

Start > Run > type services.msc

look for the service if stopped start it.

Thankx

services.msc ... does this work with Windows 98a??

you can try running sfc from the run box, to check your system files.

Eh? lost in Windows 2000 world :-)

Hummmm....its a windows 98 issue.. then you have to run a SFC scan in ur computer.

Here are the four files that were fixed:
mfc30.dll
mfco30.dll
mfcuia32.dll
setupx.dll

However, modem still does not work.

Ok

Do u see any Yellow mark in Device Manager

No yellow marks in Device Manager

Have you tried to take the modem out and try it in another slot?  Just a thought.

As stated earlier in the post, it has been tried. Thanks for the input though.

I think I am going to give up and just use a ISA modem... Only logical thing to do now.

then there is something wrong with PCI slot. Right ?

Thats what I thought, but i tried other pci slots.  Modem did not work in that slot, where the NIC and Vidio cards did work in the slots.  I don't know??

did you run sfc as i asked?

SystmProg, thanks for your advice.  I can not afford any more time trying to get this modem working.  The ISA modem is working fine for the time being.  On another topic, I seen one of the capacitors on the main board have some corrosion on the top.  Is there anyway to remove the corrosion?  Whats the chance of the computer's life lasting for another year?

>>>On another topic, I seen one of the capacitors on the main board have some corrosion on the top.  Is there anyway to remove the corrosion?

Yeah, are you familiar with dry sholedering ? you can do it by using a dry sholder.

>>>Whats the chance of the computer's life lasting for another year?

See, it depends on how old your mother board is and how do you maintain ur system weekly or monthly.

but let me know about the PCI modem...as i am very curious to resolve this issue even if you have accepted my answer but continue to resolve the issue.. :-)

Thankx

Sorry SystmProg,

I no longer have the machine in shop.  I would of loved to keep it a bit longer, but time is essential.  The problem still boggles my mind.  Next time I work on that system, I will dig further in trying to resolve the issue.  I will keep you posted! Thanks for your support.

Thankx for ur cool support :-)
