What Is This Tool?

This converter allows users to transform data transfer values from IDE (PIO mode 2) to IDE (PIO mode 4), two legacy ATA/IDE timing modes used for CPU-driven data transfer performance on older storage devices.

How to Use This Tool?

  • Enter the value measured in IDE (PIO mode 2).
  • Select IDE (PIO mode 2) as the source unit.
  • Choose IDE (PIO mode 4) as the target unit.
  • Click convert to obtain the equivalent value in IDE (PIO mode 4).

Key Features

  • Converts between two specific legacy IDE Programmed Input/Output modes.
  • Reflects differences in timing and maximum throughput settings.
  • Browser-based and user-friendly interface.
  • Supports legacy PC, embedded systems, and retro-computing applications.

Examples

  • 2 IDE (PIO mode 2) converts to 1 IDE (PIO mode 4).
  • 4 IDE (PIO mode 2) equals 2 IDE (PIO mode 4).

Common Use Cases

  • Configuring or troubleshooting timing settings in legacy BIOS or firmware for IDE drives.
  • Diagnosing performance issues on vintage computers when the system falls back to programmed I/O.
  • Benchmarking legacy storage devices in retro or industrial computing contexts.

Tips & Best Practices

  • Ensure you understand the legacy nature of these transfer modes before applying conversions.
  • Use the tool to assist with compatibility checks when maintaining or upgrading older systems.
  • Refer to device-specific documentation for timing and performance details when configuring modes.

Limitations

  • These units are only relevant for legacy hardware and obsolete transfer modes.
  • Conversion reflects timing and transfer rate differences, not actual physical storage capacity.
  • Actual device throughput varies due to hardware condition and system factors.

Frequently Asked Questions

What does IDE (PIO mode 2) represent?
PIO mode 2 is a legacy ATA/IDE timing mode defining CPU-driven data transfer performance used in older IDE drives.

Why convert IDE (PIO mode 2) to IDE (PIO mode 4)?
Users convert to compare transfer modes, diagnose performance, or configure legacy drives based on timing differences.

Does this conversion affect physical storage size?
No, the conversion covers timing and throughput characteristics, not actual storage capacity.

Key Terminology

IDE (PIO mode 2)
A legacy ATA/IDE interface timing specification for CPU-controlled data transfers using programmed I/O cycles with defined signal timing.
IDE (PIO mode 4)
An IDE Programmed Input/Output timing mode with CPU-driven data transfer control and higher theoretical throughput among older transfer modes.
Programmed Input/Output (PIO)
A CPU-driven data transfer method where the processor manages the timing and data moving cycles between host and storage device.

Quick Knowledge Check

What type of data transfer modes does this tool convert between?
