Thank you david,

right now I 'm using 16 bit card. does it mean that enabling pci has no
sigficant as there is no pci bus.
you can have a look at hardware(visit link)

do I need to write a driver for sockets of my controller?

Probably not - are you using a 16-bit PCMCIA "PC Card" or a 32-bit
"CardBus" card.  Since you have no PCI, chances are your hardware will
only support the 16-bit cards.
