CF conforms to the PCMCIA ATA interface. This effectively provides an IDE interface over PCMCIA. There are basically three ways to hook a CF into your system: * Through PCMCIA. * Directly onto the bus (kinda like PCMCIA without the hotplug). * Directly onto an IDE bus. The last is perhaps the simplest. You hook the CF onto the IDE bus with a simple cable and the system just thinks it is a hard drive. Details for this cable are available on the Sandisk www. -- Charles
