You Must copy the images in the correct sequence to the IDE-device.
Than boot using the build-in image loader the first image.
( use the "N" option to give names to images
)
When booted and the game/software asks to insert disk #2
Press SHIFT+CONTROL+2 (Or any other number for a other disk #)
So to get back to the booted disk, press SHIFT+CONTROL+1
Cheers,
