How to set up 2 DVD Writers on same motherboard, 1 Sata, 1 IDE?

I just built a new computer, Asus P5E3 Deluxe WIFI motherboard, Q9450 processor, 4 GB DDR Ram, 8800 GT 512 card and X-fi Xtreme Gamer Fatality sound card. I took my older LiteOn LH 20A1P, which is IDE, out of my old machine and put it in my new computer. I also bought the new LG GGW-H20L Blue Ray Writer which is sata, and installed it also. I have the Retail version of Windows Vista Ultimate. I have the LiteOn LH 20A1P installed with the only ide connector in the motherboard set as the master.

The problem is I can’t figure out how to make one of the DVD Writers the main drive over the other. You know D and E drives. When I was installing Vista(you know at the part where it is asking for Sata Drivers for hard drive, load drivers) it showed the LG as D drive and LiteOn as E drive. But after Vista was installed it was reversed. the LiteOn was now the D drive and the LG was the E drive. I installed Vista using the LG. I am stumped on how to know which will be what drive letter. I know if I had two IDE drives I would set one a master and the other to slave and master would be D and slave would be E drive.

Does anyone know how I can make sure one drive will be the D and the other E without changing it in Vista itself? Does Vista choose ide over Sata?

Please let me know?

Any help would be appreciated.
