Query: Is not compatible with many computers

The following answer on the D-Link tech support site says it all: "The DWL-520 requires a PCI 2.2 compliant motherboard (3.3v) in order to function. If your PCI slot is 2.1 compliant, or if the PCI slot is using 5v, then the card won't be detected by Windows and unfortunately will not work." And how will you know if you have a PCI 2.2 compliant board? Essentially, you won't, until you try the card or dig deep into the specs on your computer's motherboard. I have a very reputable ASUS Pentium III motherboard, that won't recognize this card. Very frustrating...
