- The original article has a followup to comp.sys.atari.st.tech but
- as I don't get c.s.a.s.t I must crosspots to comp.os.minix to get
- this article accepted by my newssystem. Followup-To: is set again.

- Yes, because that's the id a second harddisk at SH20[45] gets.

- But it is the right way. Your physical second disk is the logical 3rd.
- Also you can see in /usr/include/minix/config.h:
-
- ~ /* define the number of hard disk drives on your system */
- ~ /* (assuming 2 drives/controller) */
- ~ #define NR_DRIVES 3 /* typically 0 or 1 */

-
- The above define works for me.
