Are you sure he will be able to boot Linux? I thought you had to have
your boot partitions inside the first 500MB of disk space. Perhaps this
is not necessary for some of the newer hardware, I don't know. Normally
one would make a small partition for root in the first 500MB on a disk.
Another thing, is you should be able to boot from either disk. Again, I
am not sure how (or if it is possible) to do it with LILO, but the
FreeBSD
boot manager allows you to boot from other disks (I have 2 drives, one
with DOS/WIN and one with FreeBSD). He should be able to have a single
disk dedicated to NT. On the other, he can make a small partition
(known as a slice in the BSD community) for the root system (~20-30MB)
inside the first 500MB, a large DOS partition and then the rest of the
un*x stuff. There would even be room for one more partition on that
first disk (again using the common def. of a partition... in the BSD
world, each slice (DOS-partition) can have up to 8 (BSD)partitions, so
you don't need a seperate DOS-partition for the swap).
