What is IDE (DMA mode 0)?

IDE (DMA mode 0) is the lowest-speed direct memory access transfer mode defined for ATA/IDE PATA devices, allowing block data transfers to system memory without CPU-programmed I/O.

What does E.P.T.A. 2 (payload) represent?

E.P.T.A. 2 (payload) denotes the size of user or application data carried in a single message of the E.P.T.A. 2 data transfer protocol, defined by that protocol's own specifications.

Why convert between these units?

Conversion helps translate legacy block transfer data into application-specific payload sizes for accurate data handling and analysis in systems using both IDE interfaces and E.P.T.A. 2 messaging.
