IDE (DMA mode 2) to IDE (PIO mode 4)
Please provide values below to convert IDE (DMA mode 2) to IDE (PIO mode 4), or change ↔.
IDE (DMA mode 2)
Definition: Refers to DMA mode 2 for IDE devices, with data transfer rates of up to 16.6 MB/s.
Funfact: DMA mode 2 further improved performance by allowing faster data transfer rates, reducing bottlenecks in older systems.
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 2) to IDE (PIO mode 4)
1 IDE (DMA mode 2) = 1 IDE (PIO mode 4)
1 IDE (PIO mode 4) = 1 IDE (DMA mode 2)
we use cross multiplication method
IDE (DMA mode 2) → IDE (PIO mode 4)
1 → 1
1.5 → ?( suppose x)
=>1.5*1=1*x
by simplifying
x=1.5
