The CardBus slot is a 32bit PC Card slot, that is NOT backwards compatible with the older, PCMCIA Type II (16-bit) PCMCIA slots(How can I tell if I have a CardBus card?).

It will exists in newer ThinkPads, both as Type II and Type III implementations. Type III is double the thickness 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

Be aware however, that Thinkpads manufactured before ~1997-06 can NOT have Cardbus slots (v5.0+, 32-bit), and will have the original PCMCIA Type II (v2.X, 16-bit) slots (How can I tell if I have a CardBus slot?); due to timing of the availability of the PCMCIA v5.0 standard.

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.

Models featuring this Technology

(1) Type II slot

(1) Type III slot

(2) Type III slots

(2) Type II, or (1) Type III slot
