I'm using that "mount Devs:DOSDrivers/#? ~(.info)" -line on startup-sequence for mounting.
that doesnt sound good.
being in the devs:dosdrivers directory it should mount at boot time,
the command line to mount it is 'mount cd0:'
check the actuall mount list 'ie cd0'
and look in the info(using workbench) for the cd0.info line, make sure that the file system it refers to i in the L: directory and check to see if the unit id is correct
