Installing modem drivers in W98SE

My internal modem is not working in this newly reformatted system I installed Windows 98SE OS (what a surprise). Under the Device Manager tab there's question marks in front of PCI Communication Device (& the sound card). I located several modem drivers, downloaded them to floppy, created a New Folder on my Desktop & try one by one first putting in & then openning each drivers modem file but I get lost somewhere in the steps. Is anyone good enough to describe the steps in detail cause I'm really a newbie at this. I get as far as the "Then click the "Update Driver" button. A dialog box will walk you through the process. Choose "Display a list of drivers..." then choose the "Have Disk" button & use the dialog box to find the "driver files" folder you created on your desktop. Choose the .INF" file in that folder & click OK. First, I never see a".INF" file whenever I open any of the driver files be it a .exe or a .zip file! Furthermore, when that box opens up with ".INF" on the left side, & the folder on the right where you put the drop down files in (hope you know what I mean), I can never get it right. Can you please take me through this??
Oh and I'm also looking for a program on this site that will help me recover broken downloads(If I'm out of line with this, I'll post somewhere else)

 

I may or may not have the right drivers for the modem. However it's the process I'm not sure of. I want to be able to reproduce my steps for any drivers I want to install. Can you go through the process from the point I left off on my first post??
By the way there's a thing sticking up on the modem that says "Atech ATS-256" & those are the drivers I'm trying but the chip says PCTEL.

 

I have the correct drivers installed for the PCTel HSP Micro Modem 56. Got them from the Conexant website. Checked the Diagnostics tab & found the modem listed with AT commands & responses. However I still can't dial-up my ISP. Think it's got to do with the Network Connections tab. Although I do have the "Network Neighborhoods" icon located on my Desktop. I already installed my ISP installation software. I saw it right next to the "Add A New Connection" folder. Can you take me thru the steps I need to get my connection complete? I'm a newbie at this.
