 My YM chip was not socketed and I dislike the idea of bending pins. So here's a version of the mod that doesn't need it :
-* Open your STe and locale W301
+* Open your STe and locate W301
 * pins 2 and 3 of W301 are linked together by a small track on the PCB. Cut this one (carefully).
 * Cut wire 10 on the internal floppy cable, close to the motherboard side.

	This is particularly useful if you have invested in a HxC floppy emulator and you would like the ability to have it externally connected to you ST and optionally boot from it.

		+	== The DS0/DS1 signal mod inside the ST - without pin bending ==
		+
		+	My YM chip was not socketed and I dislike the idea of bending pins. So here's a version of the mod that doesn't need it :
		+	* Open your STe and locale W301
		+	* pins 2 and 3 of W301 are linked together by a small track on the PCB. Cut this one (carefully).
		+	* Cut wire 10 on the internal floppy cable, close to the motherboard side.
		+
		+	Now wire the switch as follows :
		+
		+	W301.1 ---- 1[ ]4 ---- W301.3
		+	W301.2 ---- 2[ ]5 ---- > to floppy drive pin 10
		+	W301.3 ---- 3[ ]6 ---- W301.1
		+
		+	The result is the same, and it is a bit easier to do.
		+
		+	== Additional information ==
		+
		+	For reference, the wiring of W301 is (as found in Atari STe schematics, page 3) :
		+	* pin 1 : DS0
		+	* pin 2 : to external floppy drive select
		+	* pin 3 : DS1
		+
		+	As you can see, the switch will be connecting either DS0 to internal drive and DS1 to external (as usual),
		+	or DS1 to internal and DS0 to external.
