how PCMCIA works?

Can someone help me with this? THanks. also SEE (post #3 ).

My redhat 9 is 2.4.20-8 w/ pcmcia service support. However, I installed pcmcia-cs-3.2.8 later. I have a cisco AIR-PCM352 pcmcia card installed.

- After boot, no "pcmcia" in "ps -A" list. And "cardmgr" and "pcmcia" reports "no pcmcia driver found in /proc/devices".

- I have to run "/etc/rc.d/init.d/pcmcia start" and then "/etc/rc.d/init.d/pcmcia stop" reports "device busy".

So, I doubt my pcmcia works. I have the following question.

- how to make pcmcia card service works? should I load some module in boot script? Pls consider kernel and pcmcia-cs that I installed.

- how to make a pcmcia card works?

1. Does your card turn on? (ie, beep like most cards do?)
2. It's possible that your setup of pcmcia-cs is trying the wrong chipset. Unfortunately, I don't remember the file the specifies this.
3. Have you considered upgrading to a newer Red Hat? Version 9 is old. You can upgrade to Fedora Core 3 with the CD.

Thanks. Here's more info aobut this problem. Yes, there's a beep upon the 1st insert.

March 23 - 2nd try:

+After boot with the air-pcm352 card inserted, and redhat 9 w/ 2.4.20-8 and pcmcia-cs-3.2.8:
--NO LED lit.
--"pcmcia" reports "cardmgr is stopped".
--"cardmgr" and "cardctl ident 0" and "cardctl status 0" report "no pcmcia driver found in /proc/devices".
--no driver module appears in "lsmod" list.

+Run "/etc/rc.d/init.d/pcmcia start", shows->>>>
Starting PCMCIA services: done.
cardmgr[4671]: watching 2 sockets.
--amber LED lit.
--the following modules shown in "lsmod"->>>>
Module Size Used by Tainted: P
airo_cs 4580 0 (unused)
airo 99456 0 [airo_cs]
ds 8840 1 [airo_cs]
yenta_socket 13600 2
pcmcia_core 62304 0 [airo_cs ds yenta_socket]
<<<<( "airo" and "airo_cs" are air-pcm352 card driver and loader)
-Run "cardctl status 0" shows ->>>>
5V 16-bit PC Card
function 0: [ready]
-Run "cardctl ident 0" shows ->>>>
product info: "Cisco Systems", "350 Series Wireless LAN Adapter"
manfid: 0x015f, 0x000a
function: 6 (network)
-Run "/etc/rc.d/init.d/pcmcia status" shows "cardmgr is stopped"


-Run "cardmgr" shows ->>>>
cardmgr[4731]: open_sock(socket 0) failed: Device or resource busy
cardmgr[4731]: another cardmgr is already running?
<<<< (BUT cardmgr not shown in "ps -A" nor "lsmod".)

-Run "/etc/rc.d/init.d/pcmcia stop" shows ->>>>
Shutting down PCMCIA services: /etc/rc.d/init.d/pcmcia: line 137: kill: (4672) - No such process
ds: Device or resource busy
pcmcia_core: Device or resource busy

-Run cisco card configuration tool "acu" gives "no radio found".

Does this mean pcmcia has to be loaded manually? And pcmcia seems to work and card driver not?

Any suggestion are welcome. Thanks.
