Well, it's not ``getting wormcontrol to work''. ;) Wormcontrol is a simple hook to the ioctl's of the driver, 169 lines of C code, including the copyright notice. The mere problem is to convince Yamaha to get you their SCSI documentation. Last time i've checked, they required me to fax them a sheet with figures about ``expected sales next year'' and other crap. Somebody should point them out that all their competitors have realized that providing technical specifications to their users on request is a good thing. Writing the kernel hooks should not be too difficult. If i remember right from the Linux cdwrite command, the Yamaha needs a coupld of MODE SELECTs to prepare it for writing. However, trial&error with a CD-R is like fishing in the dark... > wormcontrol doesn't seem to be available in -stable (from late > June).

The worm driver has been backported from 2.2-current to 2.1.5R, and wormcontrol(8) is also there. HOWEVER: if you want to play with an unmodified 2.1.5, get a Plasmon burner, and never boot it with a CD-ROM or fixated CD-R in the drive. Otherwise, it will announce itself as a CD-ROM (the HP 4020i will always do it this way), and be assigned to the `cd' driver. The SCSI code in 2.1.5 lacks the `type override' feature of -current, where a drive that is lying about its device type can be forcibly assigned to a `foreign' driver. -- 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. ;-)
