As HP seems to don't reveal more details about their PCI Express Wireless Lan Card, we should try to figure out first which card you've got.
I'd suggest you to retrieve some unique identifiers : The Product ID
and the Vendor ID
stored inside your device's read only memory.
You have to follow these steps under Windows XP :
- Open the
Start Menu
, right click on My Computer
, then click on Manage
.
- A new window will open up, choose
Device Manager
on the left pane of that window.
You should see a list of every devices you have inside your machine, find an Unknown Device with a big yellow Question Mark, with the name of Network Controller
:
Right-click on it, click on Properties
.
Go to the Details
tab, and choose Device Instance Id
inside the combo box, just under the Network Controller title.
Now you can see VEN_
followed by your Vendor ID
and DEV_
followed by your Product ID
.
All you have to do is telling me these identifiers by writing a comment for this question, or you can also try to search "ProductID XXXX VendorID YYYY" on Google to find at least your Wireless LAN Card model, then you will have more luck into finding a working 64 bits version for Windows XP.
Hope this helps !
