Go to device manager. A very quick way to get there that you might not know is by right clicking on my computer, and then choose manage. It opens up the Computer Management snap-in for the management console. This is the heart of your OS in one place, its pretty sweet.
Enable DMA on your IDE drives by expanding the IDE/ATAPI tree. Double click on the Primary IDE controller and choose Advanced Settings. These are the drives hooked up to your IDE chains on the computer. If the device type field is not grayed out, that means there isn´t a device there. Change the device type to "None" and Win2k will not try to autodetect devices on boot, saving some time. Otherwise, if it is grayed out, verify that the Transfer Mode is set to DMA if available. DMA greatly speeds up disk performance and makes the computer more responsive. Do the same procedure on the Second IDE Channel. Reboot if any changes were made.
