└─> 16-bit PCMCIA support

This option enables support for 16-bit PCMCIA cards. Most older
PC-cards are such 16-bit PCMCIA cards, so unless you know you're
only using 32-bit CardBus cards, say Y or M here.

To use 16-bit PCMCIA cards, you will need supporting software in
most cases. (see the file Documentation/Changes for
location and details).

To compile this driver as modules, choose M here: the
module will be called pcmcia.

If unsure, say Y.
