EDD is still INT 13h, last I checked - just function 42h rather than 2h. We use that. Nevertheless, we still get occasional reports of problems due to BIOS limitations. > > It rather depends on the pattern of free space that's available; > > consider for example the case where there's already a logical partition > > but there is another primary partition between it and the space you > > actually want to use.

Moving partitions in an OS installer as a prerequisite for actually working properly (which is a large part of what I care about given my work on Debian and Ubuntu) is far too unsafe, especially if the size of the partition exceeds half the size of the disk, as it often will. Users can of course ask for it if they're clueful, but clueful users are unlikely to run into this problem in the first place! -- Colin Watson [cjwat...@ubuntu.com] _______________________________________________ Grub-devel mailing list Grub-devel@gnu.org http://lists.gnu.org/mailman/listinfo/grub-devel
