A small addition to the handbook: You don't need to reboot your machine, the command: $ kldload atapicam Will load the module at runtime. Use /dev/cd0 instead of /dev/acd0 for all writing purposes. Maybe PCBSD does this automagiclly? Can't comment on that since I don't use PCBSD. _______________________________________________ email@example.com mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
