Anyway the first track normally is allways reserved (if the hd is used with DOS?)). Something interesting: I'm using a IDE drive as startup-drive for 386bsd. Other partitions on the drive are: primary DOS, OS/2, extended DOS. With the procedure just described I access the primary DOS partition as `C:'. The extendend DOS partition (separated by OS/2 from the pri- mary) starts at a given offset + another time one reserved track (36 sectors)!!! BTW both partitions could be accessed w/o problems :-) >(my DOS partition is first on the disk, so the whole disk partition, without >an offset should be OK, right?) The zeros are as per the README file.

But if you install 386bsd (w/ mtools and pcfs) you ought to have a strong constitution anyway (at least at the moment when you reboot and wait and wait and wait and *nothing* happens - and suddenly remember you never backed up your hd :-) Bye, Michael -- ------------------------------+------------------------------ Michael Giegerich | migieger@delos.stgt.sub.org ------------------------------+------------------------------
