That's OK with me if some space is left over. What i am asking is if i delete the ds0s4 partition (which is now an empty 2nd dos primary) and create a bsd partition of the same size, would it damage the dos (sd0s2) or OS/2 (sd0s1) partitions? I do not want to loose them by any means. Also what will hapen if i alocate the extra space beyond 4096575 (255*255*63) Willnot that confuse the adaptec 2842 bios and trash the hard drive ? I would hapily experiment with all these myself, but i do not have the capacity to back up 1.5 gigs, so i need you help. Thanks, Gyorgy Moravszky PS. It would be a lot more conviniet is the OS/2 boot manager was recognized instead of beeing "unknown", like in Linux.
