Why my SCM CardBus adapter doesn't work
Reason: SCM CardBus adapter doesn't implement ISA style IRQs.
Solution: The IBM PC Card drivers, usually try to allocate an ISA style IRQs. Since the SCM CardBus adapter (except some special implementation cases such as Compaq Armada Desk Station) doesn't implement ISA style IRQs, the IRQ request fails and all cards doesn't work. Please notice that if CardBus adapter doesn't implement 16-bit IRQs, the /IR:off switch is required.
