How to Convert IDE (PIO mode 4) to IDE (UDMA-66)
1 IDE (PIO mode 4) = 0.2515151515 IDE (UDMA-66)
1 IDE (UDMA-66) = 3.9759036145 IDE (PIO mode 4)
we use cross multiplication method
IDE (PIO mode 4) → IDE (UDMA-66)
1 → 0.2515151515
1.5 → ?( suppose x)
=>1.5*0.2515151515=1*x
by simplifying
x=0.3772727273
