How to Convert IDE (DMA mode 2) to IDE (UDMA mode 4)
1 IDE (DMA mode 2) = 0.2515151515 IDE (UDMA mode 4)
1 IDE (UDMA mode 4) = 3.9759036145 IDE (DMA mode 2)
we use cross multiplication method
IDE (DMA mode 2) → IDE (UDMA mode 4)
1 → 0.2515151515
1.5 → ?( suppose x)
=>1.5*0.2515151515=1*x
by simplifying
x=0.3772727273
