Feature: This adapter allows you to read CompactFlash cards from your camera directly through your laptop PCMCIA slot. It is the fastst way to access the card, and it appears just as a regular drive so all pictures can be drag-dropped between the card and your storage. This adapter supports all memory card sizes: 4Mb 8Mb 16Mb 32Mb 64Mb 128Mb 256Mb 512Mb 1Gb 2Gb 4Gb 8Gb 16Gb... Besides memory cards, it can also work with all other devices having CompactFlash connector provided you have the appropriate drivers for your device. I.e. the most common would be a CF WiFi or GPRS card. If you need to connect a CompactFlash Type 2 device (such as a MicroDrive), then you need a Type 2 adapter. Type 2 are a bit thicker, and therefore they require an open space above and below to fit the PCMCIA height. This adapter by itself does not require any drivers. It is a passive device. Only the CompactFlash device you connect will need drivers. Memory cards already have drivers built-into all versions of OS.
