3. Implement a socket adapter that can be programmed to (conditionally) tri-state D7 of I/0 address 3F7/377
when a CompactFlash Memory Card is installed and conversely to tri-state D6-D0 of I/O address 3F7/377
when a floppy controller is installed.
4. Do not use the CompactFlash Memory Card's Drive Address register. This may be accomplished by either
a) If possible, program the host adapter to enable only I/O addresses 1F0-1F7, 3F6 (or 170-177, 176) to the
CompactFlash Memory Card or b) if provided use an additional Primary/Secondary configuration in the
CompactFlash Card which does not respond to accesses to I/O locations 3F7 and 377. With either of these
implementations, the host software must not attempt to use information in the Drive Address Register.
This bit is 0 when a write operation is in progress, otherwise, it is 1.
This bit is the negation of bit 3 in the Drive/Head register.
This bit is the negation of bit 2 in the Drive/Head register.
This bit is the negation of bit 1 in the Drive/Head register.
This bit is the negation of bit 0 in the Drive/Head register.
This bit is 0 when drive 1 is active and selected.
This bit is 0 when the drive 0 is active and selected.
