+ * Normally, Linux can get the drive parameters from the BIOS at
+ * startup, but if this for some unfathomable reason fails, you'd
+ * be left stranded. For this case, you can define HD_TYPE, which
+ * contains all necessary info on your harddisk.
+ *
+ * The HD_TYPE macro should look like this:
+ *
+ * #define HD_TYPE { head, sect, cyl, wpcom, lzone, ctl}
+ *
+ * In case of two harddisks, the info should be sepatated by
+ * commas:
+ *
+ * #define HD_TYPE { h,s,c,wpcom,lz,ctl },{ h,s,c,wpcom,lz,ctl }
+ */
+/*
+ This is an example, two drives, first is type 2, second is type 3:
+
+#define HD_TYPE { 4,17,615,300,615,8 }, { 6,17,615,300,615,0 }
+
+ NOTE: ctl is 0 for all drives with heads<=8, and ctl=8 for drives
+ with more than 8 heads.
+
+ If you want the BIOS to tell what kind of drive you have, just
+ leave HD_TYPE undefined. This is the normal thing to do.
