Built-In and PCMCIA Wireless card type Distinction

Hi

I am trying to differentiate between a Built-In WiFi card and an
External WiFi card in Pocket PC. I tried to use the BusType. Older
devices are OK.
The bus type is "1"(Internal) for Built In and "8"(PCMCIA bus) for
External cards

But in new devices, even for Built-In wireless it says bus type as "8".


Is there any way in an NDIS IM driver, to distinguish if the medium is
an External or Built-In Wifi?

Is there any OID that helps here?

I really appreciate the help.

Thanks
