Hey Thanx for the reply, I appreciate it. Well first of all i am sorry if i 
gave this impression that i am trying to load hostap on laptop, actually it 
is running on laptop and working great for me. What i am trying to do is to 
load it on a *PC104* module with PCMIA adpater on it.  Well bridge from 
ISA/PCMCIA has been detected and that adapter working fine with orinoco 
drivers but has some issues with hostap_cs driver. well i understand a bit 
more about hostap but still cud not able to solve this issue. I will 
appreciate if you , pavel or any other can able to help with this problem.

Neways here is the problem:
I am trying to load Senao NL2511 CD card which is a prism 2 based card.  
When i start "/etc/init.d/pcmcia start"  it comes with High beep and low 
beep meaning card is not detected:(
[root at localhost hostap-driver-0.2.1]# /etc/init.d/pcmcia restart
Shutting down PCMCIA services: done.

I am using i82365 and ds module. I also tried to load the card with this 
"ignore_cis_vcc=1"
# Optional configuration parameters for hostap_cs.o
# module "hostap_cs" opts "channel=3 iw_mode=3 essid=test ignore_cis_vcc=1"

But it is still not working, well looking at 'dmesg' suggest that there is a 
clear VCC mismatch but why the vcc_ignore not working. I believe hostap_cs 
should ignore the vcc and load the services. The socket does support, 
"compaq WL110" based on hermes chipset and work with 'orinoco_cs.o '  which 
is a 5.0 V card. But it does not work with hostap_cs with Senao Card. Why is 
VCC ignore not working?


ANOTHER ISSUE WHICH  I NOTICED: THIS IS I BELIEVE AN IRQ PROBLEM:
Also i tried to load hostap_cs with Netgear PCMCIA card MA401 which is a 
VCC=5.0 card and it  does not work either. As when i plugin this card , the 
keyboard stops responding and i guess even IDE. So when i exclude all irq's 
in 'more /proc/interrupts'  by 'excluding them in 'config.opts'' still it 
hangs and does not work? Yeah !! it only 'beeps once(HIGH)' when i plugin 
VCC=5.0 V card but keyboard hangs.
Does not mean that hostap_cs is loaded but there is an IRQ issue?

Well i even looked into "hostap_cs.c" to get the idea of what is going on. 
But i am not really into hardware:(. Please suggest what is going on with 
it. If this is an IRQ problem. Then i believe there may be some solution to 
it. I will be thankful for some hints.

Looking forward to quick response.
