Boost HDD Performance

Win9x sets DMA to OFF by default. You have to switch it on. In theory, enabling DMA increases UDMA Hard Disk access to 33.3 MB/sec. In practice, speed will increase substantially from the old standard of 16MB/sec. Furthermore, DMA uses only 25% of CPU resources compared to 40% normally. Nearly all 5400rpm/7200rpm, and some lower speed, drives, support DMA.

Now I'll tell you about it. Ready ?

Open control panel and Now search for "device manager" and click properties of your hard drive. It should have an option called "DMA". By enabling this, your hard drive should show an increase in performance. Also, this method can increase the transfer rate of your CD/DVD-ROM or CD/DVD-Writer, possibly eliminating those under buffer run errors.

Again, an easy tweak which could improve you hard drive's performance
