the problem is not to boot or to run linux from an ataraid-array, the problem is to install it on such a configuration.
Making the system boot Linux off of the drives was a bit trickier,As I mentioned before, use grub as boot-manager (you also can make nice-looking menus...). It works like a charm for me!
however.
Unfortunately I know nothing about driver programming but if there would be a way to map the /dev/ataraid/dXpY to a /dev/sdX or /dev/hdX this would be cool! Then I could install linux to a remapped /dev/sdX and change with a new kernel after installation to /dev/ataraid/dXpY permanently. If you have any idea about this, lets give it a try!5) Now the tricky(ish) part. Get the modified version of lilo, from http://www.rug-rats.org/~wilfried/ (follow the V 0.1 link on the left, then there a link to lilo-hacked.tar.gz on the page). This lilo almost works, except it seems to have been writted for an earlier version of the patch, where the ataraid devices had different devices numbers. Here's my patch to geometry.c to make it work:
