I installed nt and sp6a on a clone pc with brand name components. The modem is an internal us robotics 56k. I tried to install the modem but nt does not recognise it. I checked for IRQ conficts and memory conflicts and there some issues with the memory allocation on the com1. I tried using new drivers but no luck.
I always have trouble installing internal modems, externals are no problems.
I hear that installing additional ISA drivers from the NT installation cd helps?
Any ideas?

Try this put the drivers for the modem on a floppy. Have the modem installed and go to dialup networking and install it. (You'll need the NT4 CD thats why you need the drivers on a floppy) It will say modem wasn't found. do you want to install one? or to the effect of. It's just another way around it...Good Luck!

This sounds like a BIOS/Motherboard conflict. Make sure the COM port the modem uses is not used onboard. Also, check your PCI settings, especially if you have a Plug-N-Play BIOS and/or card services.

This isn't your answer but a possible solution. Use a jumper selectable modem. This will let you select com1 thru com4 and more but you don't really more. I always use com4 because nothing ever seems to conflict with it (IRQ3-I/O 2E8).
When in NT,just add the com4 port and use default settings or set them to (IRQ3-I/O 2E8). Reboot, then in network properties, under RAS, add the modem, you can standard modem or the modem driver that came with the modem (recommended). Click on continue, let itdo its settings and reboot again.
You'll be done, it's the same process as for an external because when you select a com port on the modem via jumper settings, these settings do not change or adjust every time you turn the machine on.
There are quite a few modems still (both name brand and generic-and cost a bit more) but you may as well save the headache. You can still use that PCI USR modem on another machine running Win ME/98/95/2000 which handle PCI a little better.
I hope this info helps you.

I have installed a lot of modem for Win9x and NT and everytime is different. My solution is read the direction on the manual that come with the modem for installation. This may sound dump, but it works for me.
Good luck.

I've had the same problem when installing "WinModems" in NT.
The biggest issue is with the COM Ports.
Rather than just pointing to the drivers during the install, I've used the Setup program for the modem. This creates an applet in the control panel that will allow you to set the COM port. Use 3 or 4.

How do you define your COM 3 or 4 ports? I tried addresses and IRQ different COM 1 and 2 but I get errors in the event observers and my new ports aren't recognized. I tried too to assign IRQ 10 in the BIOS to the PCI slot where my modem is, but mysystem doesn't see it anyway. I have the same problem with my sound card...

If it will make you feel any better your not the only one who has probs with NT and internal modems, we ALL do. Especially with cheapie win modems.

One person suggested going with controller based internal and setting jumpers. I agree and would add this - in Award BIOS goto intergrated peripherals and disable COM2. Then set the modem to use IRQ3 address 2F8, your modem will then become the COM2 device. This meathod will also prevent you from having probs with software that only recognizes COM1 or 2.

I setup an NT W/S box (HP6635) for a client last summer. Machine had a WinModem with Conextent chipset, I couldn't get that piece of shit to work to save my life. Ended up using an external.

My personel machine is homebuilt clone. Modem is generic based on PCTel chipset. I had to do the same thing as the guy in answer #5.

Hope this help you.
