Or maybe NO PARITION?? I think the OLD/NEW distinction only applies when the filesystem was built on a partition that started on an odd sector. Old minix filesystems were rounded to start on the nearest even sector number. My root filesystem built, under 1.3, works just fine with a code of 0x00 because it starts on an even sector. If you have a file system built with 1.3 on a partition that starts with an odd sector, you really need to flag it as OLD_MINIX or risk having it trashed. I'm pretty sure that OLD_MINIX is not the default in at_wini! Tim Bunnell
