What is IDE (DMA mode 2)?

IDE (DMA mode 2) is a Parallel ATA data-transfer mode that enables direct memory access for devices, offering higher throughput and lower CPU usage than older PIO modes in legacy PATA/IDE interfaces.

Is E.P.T.A. 2 (signal) a standard unit?

No, E.P.T.A. 2 (signal) is a proprietary vendor- or project-specific label with no standard definition in common data transfer metrology.

When should I convert IDE (DMA mode 2) to E.P.T.A. 2 (signal)?

This conversion is useful for interpreting legacy IDE transfer metrics into specialized vendor signals used in diagnostics, performance counters, or telecom equipment telemetry.
