I don't know whether Dell factory install the Intel Application Accelerator on the Precision 360 (it doesn't apply to my Precision 650).
On the Precisions, and, indeed, all Dell machines, they tend to have the appropriate Intel chipset utility factory installed, which can cloud the exact IDE drivers in use a little (even the Microsoft drivers will appear as Intel).
The way to verify which drivers are in use is to go to the Device Manager, and open the IDE ATA/ATAPI controllers item. Double click the parent of the IDE channel that has the DVD writer on it, rather than the channel itself (if you're not sure, use View -> Devices by connection to figure it out). On the Driver tab of the resulting dialog, click the Driver Details... button.
If the driver is C:\WINDOWS\System32\DRIVERS\pciide.sys, that's the Microsoft IDE drivers. If not, you probably have the Intel Application Accelerator installed.
