After you upgrade your IBM ThinkPad-based computer to Windows 98 from
the Original Equipment Manufacturer (OEM) provided version of Microsoft Windows 95, both Personal Computer Memory Card International Association (PCMCIA) and CardBus PC-card controllers may have exclamation points next to them in Device Manager, and PC-cards do not work in your PC-card slot or slots.
CAUSE
This behavior can occur if CardBus is disabled in the Basic Input/Output System (BIOS). When this condition exists, it creates a conflict between the PCMCIA controller and the CardBus controller.
RESOLUTION
To resolve this issue, contact IBM to inquire about the availability of a fix for this issue, or enable the CardBus controller in the BIOS.
To work around this issue:
- Click Start, point to Find, click Files or Folders, type tpw.exe in the Named box, and then click Find Now.
- Click the Pccard slot Properties tab, and then click to select the Enable CardBus check box.
- On the File menu, click Exit, and then restart your computer.
