Either turn off the sector mapping, or find a sector where the mapping and the real cylinders match. At least part of the 386BSD boot sequence uses real track offsets. Like 0 (which is why it works when you do a "whole disk" install). I would suggest turning off the sector mapping. The ONLY reason for this is to allow DOS access to cylinders past 1024 without patching the BIOS, and if you're using a small DOS partition and a large BSD partition you'll never need that. You'll also get a performance improvement on BSD (cylinder groups end up on real cylinder boundaries!), and probably a little more disk space (I got an extra 30 MB on a Maxtor 4380E when I switched from the Compaq controller to my Ultrastor 12F24... and I could have gotten another 30 MB if I'd wanted to use BAD144 for all my bad-track mapping). It's a win all round. Insert obligatory flaming about idiot manuals that encourage bad procedures here, and go on to the next message... -- Peter da Silva `-_-' Ferranti International Controls Corporation 'U` Sugar Land, TX 77487-5012 USA +1 713 274 5180 "Zure otsoa besarkatu al duzu gaur?"
