Answering Y here will allow you to reverse the situation, with off-board controllers on ide0/1 and on-board controllers on ide2/3. This can improve the usability of some boot managers such as lilo when booting from a drive on an off-board controller. If you say Y here, and you actually want to reverse the device scan order as explained above, you also need to issue the kernel command line option "ide=reverse". (Try "man bootparam" or see the documentation of your boot loader (lilo or loadlin) about how to pass options to the kernel at boot time.) Note that, if you do this, the order of the hd* devices will be rearranged which may require modification of fstab and other files. If in doubt, say N. I think this is what you want.
