SYMPTOMS
When you set the AttributeMemoryHigh registry key of the PCMCIA service to a value that is larger than 0xE0000, the PCMCIA attribute memory window still has the value of 0xE0000 after you restart your computer. When this situation occurs, the PCMCIA driver may not be able to read the Card Information Structure (CIS) of the PC Card, and the enumeration of the PC Card fails.



CAUSE
Because the Microsoft Windows 2000 Pcmcia.sys driver does not recognize the AttributeMemoryHigh registry setting, users cannot change the default attribute memory location. Because users cannot change the default attribute memory location, PC Cards may not be recognized if the attribute memory window is assigned to a memory location that conflicts with undeclared ROM memory.
