under Red Hat 9 on a recent HP or Compaq Athlon PC using the O2 Micro, Inc. OZ6912
Cardbus Controller? This card worked fine on my older Compaq with Red Hat 7.3,
and works in XP.
I'm using kernel version 2.4.21-ac1 with ACPI options and without PCMCIA support.
I've compiled and installed the pcmcia-cs-3.2.4 package.
I've tried both the orinoco_cs driver and the wlan-ng driver w/o success.
I changed /etc/sysconfig/pcmcia as follows:
PCMCIA=yes #PCIC=yenta_socket PCIC=i82365 PCIC_OPTS= CORE_OPTS=
The normal beep tones do not occur when the card is inserted.
[root@xx root]# cardctl status Socket 0: 5V 16-bit PC Card function 0: [ready], [bat low] [root@xx root]# cardctl config Socket 0: Vcc 5.0V Vpp1 5.0V Vpp2 5.0V [root@xx root]# cardctl ident Socket 0: product info: "Instant Wireless ", " Network PC CARD", "Version 01.02", "" manfid: 0x0156, 0x0002 function: 6 (network)
So I believe that basic PCMCIA functionality is now working - after correcting
problems in the Red Hat 9 /etc/rc.d/init.d/pcmcia script.
I added this line to /etc/pcmcia/config.opts per a suggestion from a Compaq user:
exclude irq 10

I verified that I compiled the kernel with CONFIG_ISA=y, and CONFIG_ISAPNP=y.
The orinoco_cs module yields similar results:

"cardctl eject" just hangs, or returns "ioctl(): Device or resource busy", so I end up
rebooting each time I need to try a new experiment. The "RequestIRQ: Resource
in use" has to be the key, but which IRQ?
Suggestions?
