FreeLoader does not support ATAPI DVD-ROM on Xbox

Since on Xbox we don't have BIOS interrupts, we have to implement all Disk I/O functions manually by talking to the Xbox IDE controller directly.

Xbox have just one IDE controller with primary HDD and slave DVD.

FreeLoader is missing support for ATAPI DVD-ROM drive which Xbox have. It could not read from it, so it does not allow to test bootcd or livecd ReactOS images.

See this portion of code:

    Atapi = FALSE; /* FIXME */
