Notes

Known Issues

• This card is reported to have some incompatibilities with many notebook BIOSes.

While on some motherboards the card works fine, on some motherboards it only shows in
the PCI device list only after a warm boot, and on some others platform it will never work

Compex did not find a solution yet - Compex support forum

• In some cases, this can be mitigated by taping pin 20 of the module (as demonstrated on X61t with Middleton's BIOS). This is because the BIOS will leave the RFKILL pin (pin 20) at high-voltage while booting.
