IDE (PIO mode 4) to IDE (DMA mode 1)
Please provide values below to convert IDE (PIO mode 4) to IDE (DMA mode 1), 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 (DMA mode 1)
Definition: Refers to DMA mode 1 for IDE devices, with data transfer rates of up to 8.3 MB/s.
Funfact: DMA mode 1 offered better data transfer rates compared to PIO modes and is seen as a significant step forward in IDE performance.

How to Convert IDE (PIO mode 4) to IDE (DMA mode 1)
1 IDE (PIO mode 4) = 1.2481203008 IDE (DMA mode 1)
1 IDE (DMA mode 1) = 0.8012048193 IDE (PIO mode 4)
we use cross multiplication method
IDE (PIO mode 4) → IDE (DMA mode 1)
1 → 1.2481203008
1.5 → ?( suppose x)
=>1.5*1.2481203008=1*x
by simplifying
x=1.8721804511
