OK Larry, I'm about to throw in the towel on this one. I'm having a tough time getting to install this winmodem (USR model #3CP5699A) in my trusty Epox EP-MVP3C2 motherboard (I know, I know, shouldn't have bought it just becuz it was on sale for $9). This modem is one in which you install the driver software before the modem is physically installed, power down, install modem in a PCI slot, power up, and modem drivers are installed automatically in windows. The problem I have is in the final step: the driver does not install automatically. I know the modem is good because I can get it installed in a DFI K6BV3+/66 motherboard system and my Pentium III system at work.
Here's what's in my Epox system: AMD K6-III+ 450 mhz CPU, two 3-GB ATA33 hard drives, 32X IDE CDROM drive, floppy drive, ATI XPERT98 8 MB AGP video card, 128 MB PC100 SDRAM, serial + parallel + USB ports all disabled, NO sound card (lotsa free IRQs), Windows 98 SE OS. In System Tools, I have IRQ's 3,4,5, and 9 all free as well as several DMAs free.
Here's what I've done so far: moved the modem between PCI slots 2 to 4, tried just about every possible BIOS setting there is (on/off; enabled/disabled), done clean install of windows several times (restored image of clean install several times for convenience), installed and unistalled the VIA 4-in-1 drivers. Still cannot get the modem drivers installed automatically.
The only way I am able to get the modem installed and functional is to replace my ATI AGP video card with an old 2 MB Trident PCI SVGA (ugh) video card. I also tried a Voodoo 3 2000 16 MB AGP video card, and still had the same problem. So it works great with that dismal PCI video card but not with the 2 AGP cards that I've tried.
I've used the wmregdel.exe file every time after a failed installation.
USRobotics has not given me a clue - they just said that they don't know of any issues with the modem and the motherboard. At first they told me to contact ATI. But after I told them about the same problem with the Voodoo card, they just admitted there is a conflict of some sort with AGP cards.
There are a few BIOS combos that I think I still have to try but at this point am getting tired of hunting for the solution. Oh yes, my motherboard has the latest BIOS update.
Any suggestions would be appreciated.
