Rev. 1.0 (December, 2004)

accomplished by either a) If possible, program the host adapter to enable only I/O addresses

1F0h-1F7h, 3F6h (or 170h-177h, 176h) to the CompactFlash Storage Card or b) if provided

use an additional Primary / Secondary configuration in the CompactFlash Storage Card

which does not respond to accesses to I/O locations 3F7h and 377h. With either of these

implementations, the host software must not attempt to use information in the Drive Address

Register.
