My friend's hard drive went out and had to be replaced.  I reinstalled winxp and everything else I could think of.  All is well except it doesn't detect the modem.  Under the system hardware, it shows an exclamation by "pci simple communications controller".  I've tried to download the driver from the Dell drivers and utilities disk AND from Dell's website.  It didn't work.  I also read on a forum about making sure the Intel chipset was installed/updated.  I did that, also.  I'm using a wireless usb to get on the internet on it right now, but my friend only has dial-up access so I really need the modem.  What's the trick?  Thanks!
