- Short: Hardware hack to disable A4000 IDE port

-
- I've been using this hack on 2 A4000's for several months (since KS upped
- the delay time for IDE drives).
-
- Get a 40-pin female IDE header and wire a 5K resistor between pins 3 and 39,
- and between pins 5 and 39.
-
- Pins 3 and 5 are the high-order IDE data bits. Pin 39 is the IDE LED
- connection, which is tied high. This hack ties the two high-order IDE
- data bits high, making the ROM immediately skip looking for a drive.
-
- Plug the header onto the A4000 motherboard IDE connector, making sure it
- is on correctly.
