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

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

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
