1 out of 5 eggsDrivers did not work at all

Pros: cheap price

Cons: If you like booting in safe mode - this is the card and drivers for you. The driver install locked up my computer and I had to take the card out and send it back.

Not worth it - don't bother.

5 out of 5 eggsDesktop Install Couldn't Be Easier

Pros: Installed without a glitch in a Dell Vostro 200 (running Windows XP Pro) that only came with one d-sub connector for the monitor. Had 2 pci slots available. Installed the hardware first then ran the CD that came with it to install the driver. Connected the hardware to the new port (in this case monitor speaker data com) and bingo.

Cons: None at the moment.

Other Thoughts: May not be as compatible for laptop systems, but I can't see why if you've got a desktop and you're running Windows XP this won't work for you. If your first attempt fails and you've got more than one PCI slot available try switching to another available slot (if there's an IRQ conflict).
