IDE (DMA mode 0) to IDE (PIO mode 4)
Please provide values below to convert IDE (DMA mode 0) to IDE (PIO mode 4), 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 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 (DMA mode 0) to IDE (PIO mode 4)
1 IDE (DMA mode 0) = 0.2530120482 IDE (PIO mode 4)
1 IDE (PIO mode 4) = 3.9523809524 IDE (DMA mode 0)
we use cross multiplication method
IDE (DMA mode 0) → IDE (PIO mode 4)
1 → 0.2530120482
1.5 → ?( suppose x)
=>1.5*0.2530120482=1*x
by simplifying
x=0.3795180723
