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
# 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.
