Do you like to increase/optimize your Hard Disk I/O - read/write speed without buying expensive software utilities to do that job or changing the Hard Disk, just follow the steps. With doing these steps you will increase Hard disk speed (depends of manufacture and specification, but its worth to try).
The most speed improvement is visible with IDE drives; however there are reports that this trick also does good for SCSI disks.
In any case, it won't harm your system, so try it yourself and let me know what you find!
Just Follow the Steps:
1. Run SYSEDIT.EXE from the start & then Run command.
2. Expand the system.ini file window.
3. Scroll down almost to the end of the file until you find a line called [386enh].
4. Press Enter to make one blank line, and in that line type
5. Irq14=4096 (note: This line IS CASE SENSITIVE)
6. Click on the File menu, then choose Save.
7. Close SYSEDIT and reboot your computer.
8. Restart windows!
The speed will be effects after the your system reboots.
