1. booted slax with locked HDD - boot takes about 5 mins with my locked drive!
2. used the unlock command (unlockhd -a /dev/hda) - worked no prob
3. started xboxhd2
4. choose to go for a rebuild using selection 1.
5. inputted path (sdb1) & as heeded usual warnings...until 'Are you sure to use Primary Master [yes/no]? - it then replied 'No DNS Servers found....'
6. i then inputted full path (/usr/local/bin/qemu -hda /dev/hda -cdrom /mnt/sdb1/linux.iso -boot d) but saw a warning 'could not open 'dev/kqemu' in the console background.
Found an unrelated bug in unlockhd - it ignores the drive parameter - will fix that
