Modem Problems in a 486 Packard Bell

I'm working on a 486 Packard Bell. It has a 33MHz CPU overclocked to 66MHz (woo hoo!) and 24MB RAM. The OS is Win95B. I replaced the 2400 baud modem (an onboard daughtercard) with a 56K ISA modem.

The problem is that attempts to go online are met with the error message: "disconnected due to hardware failure."

The modem is a BestData 56SF. I am using the latest set of drivers from BestData's site. This is a jumpered modem. Jumpers are set at Com 3, IRQ 4. The settings are the same for the Com port and in the bios.

I have also tried a BestData 56F modem and a USRobotics 56K modem with similar results.

As a side note (which may or may not be related) when I first got the system it wouldn't boot because of a "keyboard error." After much frustration I discovered that if the PS/2 mouse is disconnected the system boots. At this point the PS/2 mouse is disabled in the bios and I have a serial mouse on Com 1.

Can anyone help save my final shreds of sanity???
 
Sounds to me like the motherboard is going south. I've seen more than my fair share of those Packard Bells. It's all too familiar.
 
Sounds like it's trying to use the onboard modem, try looking up the site that says which pins to jumper to disable it (I know there is one)
 
I think you're on to something, Demon-Xanth. I disabled the onboard modem in the bios. I also pulled it out and threw it away. Now I read on one of the sites you referenced that you should leave the disabled modem onboard. Yikes!
