IDE (PIO mode 4) to IDE (DMA mode 2)
Please provide values below to convert IDE (PIO mode 4) to IDE (DMA 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 (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.

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