What is IDE (PIO mode 0)?

IDE (PIO mode 0) is the slowest ATA/IDE Programmed Input/Output timing mode used for CPU-driven data transfers between a host and storage device, mainly for very old drives and controllers.

Why convert IDE (PIO mode 0) to IDE (PIO mode 2)?

Converting helps compare or interpret legacy data transfer speeds and timing standards when diagnosing vintage hardware or configuring BIOS/firmware.

Is this conversion applicable for DMA transfers?

No, this tool is meant only for non-DMA CPU-driven IDE transfers as part of legacy hardware diagnostics.

What Is This Tool?

This tool allows users to convert data transfer rates between IDE (PIO mode 0) and IDE (PIO mode 2), which are legacy ATA/IDE CPU-driven timing modes used in older storage devices. It aids in understanding and comparing timing standards for vintage hardware.

How to Use This Tool?

Enter the value measured in IDE (PIO mode 0) in the input field.
Select 'IDE (PIO mode 0)' as the from unit and 'IDE (PIO mode 2)' as the to unit.
Click the convert button to view the equivalent value in IDE (PIO mode 2).

Key Features

Converts data transfer values between IDE (PIO mode 0) and IDE (PIO mode 2).
Supports legacy ATA/IDE PIO timing mode standards.
Browser-based and easy to use without additional software.
Helps diagnose vintage PC and embedded system performance issues.

Examples

1 IDE (PIO mode 0) equals approximately 0.3976 IDE (PIO mode 2).
10 IDE (PIO mode 0) converts to roughly 3.9759 IDE (PIO mode 2).

Common Use Cases

Configuring or interpreting legacy BIOS/firmware drive timing for older IDE hard drives.
Diagnosing performance or compatibility on vintage PCs where DMA transfers fall back to PIO modes.
Reading device driver or utility reports indicating IDE device transfer modes.
Conducting diagnostics, data recovery, and maintenance on legacy IDE hardware.

Tips & Best Practices

Use this tool when working with legacy hardware or embedded systems lacking DMA support.
Cross-check converted values during vintage PC diagnostics for accurate interpretation.
Understand that this conversion relates to theoretical timing, not real-world throughput.
Apply conversions carefully when configuring BIOS or firmware IDE timing settings.

Limitations

The conversion only reflects theoretical timing and performance differences between PIO modes.
It does not account for actual throughput variances caused by device condition or system specifics.
Relevant solely to CPU-driven, non-DMA transfers on legacy IDE devices.
