When you are running Windows 98 Second Edition or Windows Millennium Edition (Me) on a computer that supports the Advanced Configuration and Power Interface (ACPI) specification, you may experience the following symptoms with certain CardBus cards and certain Texas Instruments CardBus controller chip sets:
If you start your computer with no CardBus card inserted, and then you insert one of the affected CardBus cards, the following symptoms may occur:
The mouse pointer may alternate rapidly and continuously between a regular pointer and a busy (hourglass) pointer.
The computer may perform very sluggishly.
The CardBus card never finishes being initialized.
If you start your computer with one of the affected CardBus cards inserted, the following symptoms may occur:
The computer may stop responding (hang) while attempting to detect the CardBus card (for example, a PCI Ethernet controller).
Removing the CardBus card may allow the computer to finish detecting the device and installing drivers.
The exact symptoms may vary slightly depending on the computer, specific CardBus controller model, and CardBus card used.
On an ACPI-enabled computer that uses certain Texas Instruments CardBus controllers, inserting a CardBus card that does not support power management can result in a continuously asserted Power Management event (PME) being signal by the controller. This causes the card to be continuously re-enumerated.
