Newer Sun boot firmware knows how to soft-set sector sizes. MS-DOS' MSCDEX chokes on drives that don't run 2048-byte sectors. FreeBSD doesn't give a damn. This used to bite me when I was moving CD drives around; you'd have it set to 512 for SunOS installs, drop it back on the BSD box, all would work, then drop to DOS to do something reprehensible and argh! the CD no work 8( Unnerving. > Gary Palmer FreeBSD Core Team Member -- ]] Mike Smith, Software Engineer msmith@atrad.adelaide.edu.au [[ ]] Genesis Software genesis@atrad.adelaide.edu.au [[ ]] High-speed data acquisition and (GSM mobile) 0411-222-496 [[ ]] realtime instrument control (ph/fax) +61-8-267-3039 [[ ]] Collector of old Unix hardware.
