After you install Windows XP on a computer that has an ATI RAGE 3 Mobility video adapter, Device Manager lists an "Unknown device" under "Other devices." A yellow circle with a black exclamation point on it appears next to this "Unknown device."
STATUSMicrosoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article. MORE INFORMATION
You can ignore this issue. Although the "Unknown device" Plug and Play Identifier does point to the ATI RAGE 3 Mobility video adapter, Device Manager enumerates the video adapter correctly, and the video adapter functions normally.
