Please provide values below to convert IDE (PIO mode 4) to IDE (PIO mode 2), or change ↔.
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.
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.

How to Convert IDE (PIO mode 4) to IDE (PIO mode 2)
1 IDE (PIO mode 4) = 2 IDE (PIO mode 2)
1 IDE (PIO mode 2) = 0.5 IDE (PIO mode 4)
we use cross multiplication method
IDE (PIO mode 4) → IDE (PIO mode 2)
1 → 2
1.5 → ?( suppose x)
=>1.5*2=1*x
by simplifying
x=3
