This document covers IBM integrated (MiniPCI), Cardbus and PC Card (PCMCIA) Wi-Fi devices.

Finding out which adapter you have

For MiniPCI or Cardbus adapters run the command: 

 lspci -n | grep "Class 0200"

And compare the PCI IDS with the ones below.

Note: This will also return the PCI IDS of any Ethernet adapters, as Ethernet adapters and Wireless adapters share the same PCI Class ID.

NOTE!
Only the IBM Parts will work, any other parts will give an 1802 error on Post because the sub-vendor PCI ID is different, see Problem with unauthorized MiniPCI network card for more details

There is a way to get rid of the 1802 Bios error. Make a Boot Floppy and Copy this onto it. Boot of the floppy and execute the 1802.com file. Shutdown and build in your card. The error will not appear All Done

"Unauthorized" MiniPCI network card

Attempts to install an unsupported card will result in the following message: 

  1802: Unauthorized network card is plugged in - Power off and remove the miniPCI network card.

For a resolution, see the Problem with unauthorized MiniPCI network card page.

Cardbus adapters

Cardbus is a 32bits bus that runs at 33MHz, and is in many ways simular to the PCI bus. In fact under Linux Cardbus adapters are handled by the PCI subsystem.
You can differentiate a PC Card adapter from a Cardbus adapter as the later has a gold coloured grounding strip

PC Card (PCMCIA) adapters

PC Card or PCMCIA (Personal Computer Memory Card International Association) as it used to be called, is an 8 or 16bits bus limited to 8MHz, in many ways simular to the old ISA bus and not suitable for highspeed devices.
