forcing 16bit pio writes, disabling 32bit pio writes. This was already the case for read pio ever since this driver got imported. This fixes booting from IDE drives in PIO mode with both the IDE and ATA busmanagers, at least on my ASUS P5E3 mainboard. If I am stepping out of bounds here please correct and let me know..
