IDE (DMA mode 0) to IDE (PIO mode 1)
Please provide values below to convert IDE (DMA mode 0) to IDE (PIO mode 1), or change ↔.
IDE (DMA mode 0)
Definition: Refers to Direct Memory Access (DMA) mode 0 for IDE devices, with data transfer rates of up to 4.2 MB/s.
Funfact: DMA mode 0 allowed the system to transfer data directly between devices and memory, reducing CPU overhead compared to PIO modes.
IDE (PIO mode 1)
Definition: Refers to PIO mode 1 for IDE devices, with data transfer rates of up to 5 MB/s.
Funfact: PIO mode 1 offered an improvement over mode 0, allowing for faster data transfer without requiring DMA support.

How to Convert IDE (DMA mode 0) to IDE (PIO mode 1)
1 IDE (DMA mode 0) = 0.8076923077 IDE (PIO mode 1)
1 IDE (PIO mode 1) = 1.2380952381 IDE (DMA mode 0)
we use cross multiplication method
IDE (DMA mode 0) → IDE (PIO mode 1)
1 → 0.8076923077
1.5 → ?( suppose x)
=>1.5*0.8076923077=1*x
by simplifying
x=1.2115384615
