Does the BookType will reset to normal when I restart the PC?

When I use some BookType utility to set the BookType to DVD-ROM, will it save the value to the DVD-RW drive? Or the BookType will reset to nomal when I restart the PC?

It will reset to normal. If you have auto-bs, it will reset to -ROM.

Yes it will reset if you reboot your PC - since DVD burner is also reset at boot-up(restart).
