Hi, following bsdllabel output caught my attention: # size offset fstype [fsize bsize bps/cpg] a: 2097152 0 4.2BSD 2048 16384 28552 b: 4194304 2097152 swap c: 312576642 0 unused 0 0 # "raw" part, don't edit d: 33554432 6291456 4.2BSD 2048 16384 28552 ... I created this disk with sade or sysinstall. What I'm not sure about is that partition 'a' has an offset of 0. With an 8k big /boot/boot I would guess offset should be 16block large. But since the disk is booting, some boot1 loader ist located at sector 0 (from the beginning of this slice). How is it assured, that the first block will never be overwritten? Where is boot1 located, where boot2? Comparing the first sector with boot and boot1 differs already at the first char. (and there were no updates so far) Little bemused regards, Adam --
