like floppy or CD boot. This allows it to reduce the number of scans needed to identify the boot partition - when booted from a real floppy, this speeds up the boot process by a magnitude. Also, the loader now has a fall back in case there were no "boot" links on the disk - the current boot floppy script doesn't create them. With these changes, I was able to boot into a HD based Haiku installation from a floppy disk. It's not yet enough to boot from CD (as the boot device selection is a bit too simplistic right now), but it will eventually come next. Testing is a lot slower here, though, as neither qemu nor Bochs support multi-session CDs (at least I have no idea how to get them to do this). git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@14380 a95241bf-73f2-0310-859d-f6bbb57e9c96
