Changes to XTIDE Universal BIOS:

• XTIDE rev 2 and modded XTIDE rev 1 work again (fixed A0<->A3 swap when accessing Control Block Registers).
• System INT 13h handler is no longer copied to INT 40h (testing if something uses INT 40h).
• Removed controller hardware reset: now AH=0h and AH=Dh will only re-initialize drives (SB16 Tertiary and Quaternary IDE should now be safe to use when using Secondary IDE).
