SYMPTOMS
A Personal Computer Memory Card International Association (PCMCIA) device that works correctly in Microsoft Windows 98, Microsoft Windows 98 Second Edition, Microsoft Windows Millennium Edition, and Microsoft Windows 2000, may not work correctly in Windows XP. If this problem occurs, a black exclamation point (!) on a yellow field is displayed on the device in Device Manager. Additionally, no resources will be allocated to the device.



CAUSE
This problem can occur if the PCMCIA device has its configuration information in common (working) memory instead of attribute memory (where the Card information structure (CIS) and configuration registers are mapped). The Pcmcia.sys driver in Windows XP does not recognize such devices, and because of this, does not allocate resources to the device.



RESOLUTION
To resolve this problem, obtain the latest service pack for Windows XP. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:
