What Is This Tool?

This tool enables conversion between two legacy IDE data transfer modes: IDE (PIO mode 2) and IDE (UDMA-66). It helps users interpret and compare transfer rates relevant for configuring older storage devices in vintage or legacy systems.

How to Use This Tool?

  • Enter a data transfer value in IDE (PIO mode 2) units
  • Select IDE (PIO mode 2) as the source unit and IDE (UDMA-66) as the target unit
  • Click convert to get the equivalent value in IDE (UDMA-66)
  • Use the result to inform configuration or comparison of IDE transfer modes

Key Features

  • Converts data transfer values between IDE (PIO mode 2) and IDE (UDMA-66)
  • Supports analysis of legacy IDE drive performance and compatibility
  • Provides examples for clear understanding of conversion results
  • Browser-based and easy-to-use interface

Examples

  • 10 IDE (PIO mode 2) × 0.1257575758 = 1.257575758 IDE (UDMA-66)
  • 5 IDE (PIO mode 2) × 0.1257575758 = 0.628787879 IDE (UDMA-66)

Common Use Cases

  • Configuring legacy BIOS or firmware drive timing settings for older IDE devices
  • Diagnosing performance or compatibility on vintage PCs when switching from DMA to PIO mode
  • Reading device driver reports on drive transfer modes
  • Specifying or verifying burst throughput capabilities of PATA (IDE) storage
  • Selecting transfer mode in BIOS or legacy operating systems
  • Benchmark interpretation and troubleshooting IDE transfer errors

Tips & Best Practices

  • Understand the distinction between CPU-driven PIO and burst-mode UDMA transfers
  • Use this tool to compare historical transfer rates during vintage hardware tuning
  • Confirm hardware and cable compatibility before attempting UDMA-66 configurations
  • Refer to this conversion when interpreting driver or benchmark data related to IDE devices

Limitations

  • Conversion values are theoretical and reflect maximum transfer rates only
  • Actual transfer speeds depend on hardware quality, cable type, and system environment
  • PIO mode 2 is much slower and less efficient compared to UDMA-66
  • Not all systems support UDMA-66 without hardware upgrades

Frequently Asked Questions

What does IDE (PIO mode 2) mean?
It is a legacy CPU-driven transfer mode specifying timing for older IDE drives using programmed input/output cycles.

What is IDE (UDMA-66)?
IDE (UDMA-66), also known as Ultra DMA Mode 4, defines a faster Parallel ATA transfer mode with a maximum theoretical rate of 66.7 MB/s.

Why convert from IDE (PIO mode 2) to IDE (UDMA-66)?
To compare or upgrade legacy transfer modes for better performance and compatibility in vintage or legacy IDE storage setups.

Key Terminology

IDE (PIO mode 2)
A legacy CPU-driven transfer mode for IDE devices defining timing and maximum effective data transfer rates using programmed I/O.
IDE (UDMA-66)
Also called Ultra DMA Mode 4, a Parallel ATA transfer mode supporting burst transfers at up to 66.7 MB/s using an 80-conductor PATA cable.
Burst Transfer
A data transfer method where blocks of data move rapidly in bursts rather than one unit at a time.

Quick Knowledge Check
