What does IDE (DMA mode 1) mean?

IDE (DMA mode 1) is a Direct Memory Access transfer mode for IDE/ATA devices, enabling data movement directly to or from system memory with limited CPU use.

How does IDE (PIO mode 2) differ from DMA mode?

IDE (PIO mode 2) utilizes CPU-driven programmed input/output cycles instead of DMA, involving different timing standards for data transfers on legacy IDE hardware.

Why convert between these two IDE modes?

Conversion helps compare and configure transfer performance settings, aiding in troubleshooting, legacy system tuning, and interpreting device driver reports.
