Remarks
Some System BIOS do not scan on CardBus bus, if they are asked to look for a PCI device. Imagine that there would be a common PCI Chipset with drivers and no special CardBus client. if the device is present at boot time and the PCI driver uses the OEMHLP$ driver (included in OS2KRNL), chaning OEMHLP$ to OEMH2$ would let the PCI driver find the CardBus device. Of course you must make sure that the card is in the socket all the time.
Additionally, this driver adds a write protection filter to a socket where an USB card is inserted.
