CardBus slot

The CardBus slot is a 32bit PC Card slot, that is backwards compatible with the older 16-bit PCMCIA standard.

It exists in ThinkPads both as a Type II and Type III implementation. Type III is double the tickness of Type II, and most Type III implementations can accept two Type II cards.

• A Type III slot can accept a Type III, Type II or Type I card
• A Type II slot can accept a Type II or Type I card

Linux support

Cardbus adapters are handled by the Linux PCI subsystem as hotplug PCI adapters.

PCMCIA adapters where handled by the older Linux PCMCIA package, until the 2.6 kernel where PCMCIA hotplug is now directly supported.
