Inspiron 6000 network devices

I am helping a friend with her Inspiron 6000. I had to re-install Windows XP because it would not boot. I then downloaded and installed selected drivers. I am now trying to determine if there is any wireless device in this laptop.

Device Manager indicates a wired network connection of Broadcom 440x 10/100 Integrated Controller for which I had installed the driver.

It also displays a PCMCIA adapter described as Ricoh R/RL/5c476(II) or compatible card bus controller. I believe that is the bay above the hard drive which is currently vacant.

The BIOS has a section for onboard devices and lists a MiniPCI device with a status of enabled. The BIOS has a section labled Wireless. In that section it shows an item for wireless control of a MiniPCI & Bluetooth controller and a factory setting of ON (or Fn&F2). It also has a section labled Wireless Devices with a factory setting of ON. I don't know if that is evidence of any hardware.

The service tag for this machine is <ADMIN NOTE:Service tag removed per privacy policy> if anyone wants to look at the original configuration.

Can anyone tell me if there is a wireless device in this machine? And if so, what driver do I install or how to turn it on. It appears to me that there is none and my best bet would be to get a PCMCIA based wireless n device. I see one at Amazon for $8.
