IDE (DMA mode 0) to IDE (UDMA mode 1)
Please provide values below to convert IDE (DMA mode 0) to IDE (UDMA 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 (UDMA mode 1)
Definition: Refers to UDMA mode 1 for IDE devices, with data transfer rates of up to 25 MB/s.
Funfact: UDMA mode 1 became widely adopted in the late 90s and early 2000s, offering faster transfer rates than earlier PIO and DMA modes.

How to Convert IDE (DMA mode 0) to IDE (UDMA mode 1)
1 IDE (DMA mode 0) = 0.168 IDE (UDMA mode 1)
1 IDE (UDMA mode 1) = 5.9523809524 IDE (DMA mode 0)
we use cross multiplication method
IDE (DMA mode 0) → IDE (UDMA mode 1)
1 → 0.168
1.5 → ?( suppose x)
=>1.5*0.168=1*x
by simplifying
x=0.252
