hi, Did you install the drivers for the the intel pro card? if not you could get it from here. http://support.dell.com/support/downloads/type.aspx?c=us&l=en&s=gen&SystemID=LAT_PNT_PM_D600&os=WW1&osl=en&deviceid=7039&libid=5

hope that helps.

I've tried those actually. Windows will detect the card as a network controller, but no version of the drivers, Intel's or Dell's, have worked with the card.

Perhaps your computer is confusing the truemobile drivers with the intel pro wireless. I would try to uninstall any previous wireless drivers and re-install the intel pro wireless drivers next.
However if you have exhausted all possible options and are still unable to make it work, as a last resort, i would do a fresh install of XP and reinstall the dell drivers one by one. Hopefully that should get it to work.

The laptop BIOS may not recognize the device because it likely has a limited list of devices that are known network adapters, and your card might just not be on the list (I don't know this as fact, but I've seen the behavior many times). Here's my way of indentifying unknown network hardware and getting it up and running:

1) Boot Windows and open the Device Manager (Start -> Run -> devmgmt.msc -> Enter).

2) Find your unknown network adapter in the list, right click it, and choose Properties.

3) In the Properties window, go to the Details tab. You'll see something along the lines of PCI VENDOR ID and DEV or DEVICE ID, and two four-character strings (perhaps VENDOR 8086 and DEV 1013).

PCI devices, including MiniPCI, are identified by a Vendor ID and Device ID. Not surprisingly, the Vendor ID is the manufacturer of the chipset on the card, and the Device ID indentifies that particular model card in their line of products.

4) Google these two strings (just put in "pci 8086 1013" with no quotes) to find out who makes the card and what model card it is.

5) Go to the manufacturer's site and download the corresponding drivers.

Some common Vendor IDs for PCI/MiniPCI network cards:
8086 Intel
14E4 Broadcom
168C Atheros
10B7 3Com
1668 Actiontec
1137 Cisco

I'll try that trouble shooting option.

What's funny is my dogs got a hold of the card, laying in an anti-static bag on my desk, and bit some resistors off.

I have to buy a new one now.
