Dell Latitude CPx - New Hard Drive - One Driver Missing - Xircom Modem/LAN Not Working Either

I had to put a new hard drive into a Dell Latitude CPx and reinstall everything from scratch. I'm using Win 98SE. There is one driver still needed, according to the device manager, having to do with PCI. If I switch to the By Connection view, it comes under one of the PCMCIA connectors, the lower one on the list, if that matters.

At the same time, I'm trying to install the driver for a Xircom LAN and Modem card, and the modem side won't work but the LAN side does.

I'm assuming this one missing driver would fix all this. I've gone to the Dell web site for this unit and haven't been able to determine which driver is missing.

Any ideas?

Did you look here on the Dell Site should tell you exactly what drivers are needed for your model

The pci device could be for the xircom modem which is now owned by intel which is why the dell site might not be helping you.

Go to this site: http://downloadfinder.intel.com/scripts-df/support_intel.asp whic his intels website.

Mouseover the section which says: "networking and communications" and then mouse over the bottom of the list till it scrolls up and you see "xircom archived drivers" and then mouse over that and then click on your particular adapter.

Once you click on your adapter, go aehad and download the driver and install it.

It might resolve both of your issues (which i think are the same- pci communciations device which are usually modems under pcmica which means a pcmcia modem).  Too many whichs in that sentence, LOL.

This case was cracked by installing a standard Windows modem driver first.

The card is labelled as a Xircom RealPort CardBus Ethernet 10/100+Modem 56 (RBEM56G-100). The standard drivers that (sort of) worked were either the (Standard Modem Types) "Standard 56000 bps K56Flex Modem" or "Standard 56000 bps V90 Modem". However, both of these only connected at 19,200 bps. (The "Standard 56000 bps X2 Modem" driver didn't work at all.)

Installing one of the standard drivers got rid of the "unknown device" (and sometimes listed as "PCI device" or such) alert in the Device Manager and, obviously, allowed dialing in.

This, in turn, allowed the Intel firmware update to see the modem now and perform its firmware update, after which I could install the driver downloaded from Intel. The one downloaded from Dell might have worked as well.

The final twist in the case was that during driver installation, the RBEM56G-100 was referred to as the RealPort device, so this is what I pointed to. Upon reboot, the CardBus version of the driver installed itself. The computer could not communicate with the RealPort driver but was able to use the CardBus driver. (This might have shortened the debugging if I had tried the CardBus driver earlier, but if I remember correctly, it appeared to be for a model other than RBEM56G-100.)

There were now two modems listed in the PC. The CardBus version will connect at 40+ kbs, and the RealPort verion will not work. I deleted the RealPort one and kept the CardBus one and the problem is resolved.

Again, the initial problem with the missing driver in the Device Manager was resolved by installing a standard modem driver, which then allowed communication with the Xircom and enabled the rest of the updating process.

By the way, the network side of the Xircom worked all along.
