How to increase the hard disk speed in Windows XP/2003?

To speed up your hard disk speed we need to configure a special buffer in the computer's memory in order to enable it to better deal with interrupts made from the disk.

This tip is only recommended if you have 256MB RAM or higher.

Follow these steps:

  1. Run SYSEDIT.EXE from the Run command.

  2. Expand the system.ini file window.

  3. Scroll down almost to the end of the file till you find a line called [386enh].

  4. Press Enter to make one blank line, and in that line type

Irq14=4096

Note: This line IS CASE SENSITIVE!!!

  1. Click on the File menu, then choose Save.

  2. Close SYSEDIT and reboot your computer.

Done. Speed improvement will be noticed after the computer reboots.

This is a myth
In Windows 9x the system.ini file was used for important system settings. However, this was never the case for the NT platform. In these systems the system.ini is almost obsolete, being retained only for compatibility with old 16 bit applications. All other settings will be ignored.

From a technical standpoint the setting makes no sense. Buffers are used by devices, not IRQ's. Assigning a buffer to an IRQ would be pointless. You will find no reference to this setting in any Microsoft Documentation.
