IDE (PIO mode 2) to IDE (PIO mode 4)
Please provide values below to convert IDE (PIO mode 2) to IDE (PIO mode 4), or change ↔.
IDE (PIO mode 2)
Definition: Refers to PIO mode 2 for IDE devices, with data transfer rates of up to 8.3 MB/s.
Funfact: PIO mode 2 continued to improve transfer rates, becoming a common standard in the late 1990s before DMA modes gained popularity.
IDE (PIO mode 4)
Definition: Refers to PIO mode 4 for IDE devices, with data transfer rates of up to 16.6 MB/s.
Funfact: PIO mode 4 was often used in older systems but was gradually replaced by more efficient transfer modes, such as DMA and UDMA.

How to Convert IDE (PIO mode 2) to IDE (PIO mode 4)
1 IDE (PIO mode 2) = 0.5 IDE (PIO mode 4)
1 IDE (PIO mode 4) = 2 IDE (PIO mode 2)
we use cross multiplication method
IDE (PIO mode 2) → IDE (PIO mode 4)
1 → 0.5
1.5 → ?( suppose x)
=>1.5*0.5=1*x
by simplifying
x=0.75
