I've been too lazy to look there. :) Anyway, as long as one couldn't get it to work with `scsi -e', i'm afraid the code in the kernel won't work neither. Oh well :), i just wanted to provide a quick'ndirty hack for experimenting, but had to find that it's already there in mt(1)! If it works, the only patch that will be needed is to remove the line ``(Not yet implemented.)'' from the man page. ;-) So folx, try it! -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
