Help! Modem problem. How connect modem?

[Danny Berg]

My use of the internet gets real slow and then so slow that it stops and won't work at all and I need to resolve this. I have another computer I hook to the same phone line and it works fine. I figured the modem was bad so I purchassed a new U S Robotics model 2630094 PCI modem (I chose this exact modem because I know of another pc computer that works very well with this 56K modem it says USR90-11 on the chip). I took out the existing modem and replaced with the new one in same PCI area and the system would not boot into windows did get some DOS stuff. Tried a different PCI slot got windows logo to come up but no real desktop. Nothing will work. Reinstalled old modem and it boots up. NOTE: original modem doesn't actually use the PCI bus it has a multipin connector that plugs into a jack that is built into the motherboard right in front of the PCI slot.
Specs: Motherboard Amptron PIII-3758TLM V5.2 micro ATX, chipset SiS630eT, VGA Audio: yes/yes, Modem/Lan: yes/yes, Dima/DDR: 2/2, ISA/PCI/AGP/AMR: 0/3/0/0. Intel PIII 933mhz, 128 ram, Windows 98SE.
Any help would be appreciated.
Thanks,
Danny

Sounds like that original modem was using the AMR slot. What you could try is to start back with original config, and modem. Once in windows either remove that modem from controlPanel>Modems or from the device manager then shutdown, remove old modem, then install new modem, and PC should boot and find new hardware and prompt you for drivers for this new modem.. You probably will see great improvement with this new modem, reviews of those AMR modems show that they are not so great...

To install the USR, you will have to enter BIOS setup, and disable the AMR/CNR slot, as well as any IRQ assigned to that slot.
