What is IDE (PIO mode 1)?

IDE (PIO mode 1) is a data transfer mode where the CPU controls each transfer cycle on legacy PATA devices, offering moderate throughput but higher CPU overhead.

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

E.P.T.A. 2 (payload) refers to the application data amount carried within a single message of the E.P.T.A. 2 protocol, defined by that protocol's own specification.

Why convert between IDE (PIO mode 1) and E.P.T.A. 2 payload?

Converting helps analyze and optimize data transfer efficiency when legacy PIO-based transfers interact with messages in the E.P.T.A. 2 protocol.
