 Replying to [comment:2 starsseed]:

Our booting process does not handle the "drive number" passed in the DL
 register, either, stopping us to boot Haiku from "BootManager" when it's
 not installed on the boot drive.

 I'm quite sure I've seen DL being passed around in several places as boot
 drive, at least the MBR code and stage1, didn't check bootman though.
