Not come across Smart Boot Manager but I wonder if it creates a small partition to run from; the OS/2 Boot Manager, which was also shipped with older versions of Partition Magic, did but, like "recovery" partitions it didn't get a drive letter. Try running: # dd if=/dev/ad0 of=/tmp/foo bs=512 count=1 # hd /tmp/foo > /tmp/foo.hd This copies the first sector of the disk to a file and hd(1) does a hexdump of the binary file. Open /tmp/foo.hd in an editor and look at the last 4 lines, they should look similar to: 000001b0 00 00 00 00 00 00 00 00 00 00 00 00 00 00 80 01 000001c0 01 00 a5 7f ff 10 3f 00 00 00 41 97 60 00 00 00 000001d0 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 000001e0 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 000001f0 00 00 00 00 00 00 00 00 00 00 00 00 00 00 55 aa 00000200 (there will be the ASCII to the right of each line but I've not included it to prevent wrapping in the e-mail) The partition type is the third hex number in the last 4 lines; the example above is 'a5' (FreeBSD) and the disk has only one partition which is why the other 3 lines are all zeros. Post the file /tmp/foo.hd here as other stuff may yield clues. Regards, Mark
