Hi Michael,

thanks for all your inputs.

I have made orinoco_cs.c driver recognise my card (D-link DWL50)
with ignore_cis_vcc = 1 option and card is successfully
configured.

But same thing if i try with my driver, i have failure returned at
card services (RequestIO) call. I don`t know why this is
happening?? and i have checked throughly my driver code..its seems
that no problem with the code(because my driver is working fine in
compaq Armada notebook).

now i am in deadlock situation, not able to proceed further..

Pls see the log below,
This is the output in /var/log/messages:
(some debug messages are added by me for testing)
