PCI Modem Installation

PCI Modem Installation

PCI Modem Installation

(OP)
When I recently installed an old Modem (DSI Internal FAX Modem - V90, 56,000 bps) in a new computer, the computer would not recognize it on PNP.  I installed it "manually" but it decided to connect to Com port 1.  Now it won't work.  How can I change to port setting for Windows 98?

RE: PCI Modem Installation

Maybe you need to specifically allocate an IRQ to the relevant PCI mobo slot in the BIOS...

You said "Now it won't work."  -  Does that imply that you did have it operating in this PC at some stage?

RE: PCI Modem Installation

Any internal modem cannot use Com 1 or 2. These are external ports.
You have to use com 3 or 4.
As soon as you change to the correct port it will work.

Hope this help

The modem worked in another PC.
How do I change the Port settings?

RE: PCI Modem Installation

When you install the modem use the OEM driver that you received with the modem. Follow the prompts and choose Com 3/4.

That should do it.

Hope this helps

RE: PCI Modem Installation

That won't do it, because com 3 and 4 won't show up.
You can't arbitrarily assign any com port to an internal PCI winmodem, they'll use the com and IRQ of whatever slot they're in on your motherboard. Internal winmodems use a virtual com port, assigned by hardware, NOT windows.
You CAN use com 1 or 2, providing you DISABLE it in BIOS setup first!
You should read the posts in the "General Modem Discussion" forum. There are hundreds of similar situations, and the explanations, step by step, on how to PROPERLY install a winmodem so it works.

Cheers,

RE: PCI Modem Installation

Com 3/4 are virtual ports to that I agree.
IRQ & Port has nothing to do with what slot the hardware is in.....
It depends on the software/chipset of the hardware and the bios.
In the old days you had jumpers to determine what IRQ you need the hardware to be on. Today they use plug and pray (plug & play) to do the same thing.
Depending on your BIOS you can assign an IRQ to a slot, if not it will use whatever is avialible.

Hope this clears it up

"IRQ & Port has nothing to do with what slot the hardware is in....."
Fine, you obviously know more about hardware and installing modems than me.

RE: PCI Modem Installation

I agree with "Comtech" compleatly, try to free up IRQ 10 or 11, winmodems like them, but just like "Comtech" said "it all depends on the slot it's in". Good luck sometimes it can be a real hair puller.
