Antenna Coupling Mechanism
regarding the FCC Part 15.203 and RSS 210 §5.5
The following is the mechanism regarding the FCC Part 15.203 and RSS 210 Section 5.5 to
prevent an unauthorized connection between the applying mini-PCI wireless card and the built_in
antenna of the applying host unit (IBM ThinkPad T30 Series).
1. If the BIOS of ThinkPad T30 Series finds that the base class code of the applying mini-PCI card
is “02h”, the BIOS regards it as a network mini-PCI card.
2. If the BIOS detects a network mini-PCI code (i.e. =“02h”), the BIOS checks the vender ID,
device ID, subvendor ID and subsystem ID of it.
vender ID : Chipset manufacturer ID
device ID : Chipset device ID
subvendor ID : WLAN assemble manufacturer ID
subsystem ID : Dealer ID à IBM unique code will be assigned by the card supplier.
3. If one or more of these IDs was(were) different from supported IBM options which were
authorized by the FCC and Industry Canada to use for ThinkPad T30 Series, the BIOS will
stop the boot and show a POST error with beeps.
The following step 4 is backup logic if a wireless card will not be specified with the above IDs.
4. The BIOS also checks PCI VPD(Vital Product Data) contents. If a product name of mini-PCI
card written in VPD, which is provided from Flash ROM of the applying mini-PCI wireless card,
was different from supported IBM options, which were authorized by the FCC and Industry
Canada to use for ThinkPad T30 Series, the BIOS will stop the boot and show a POST error
with beeps.
