i cannot think of a way how the data should come from the cdrom to ram and then to disk _without_ many an interrupt >> btw, ripping from /dev/hdb, encoding with gogo (nice +20) _and_ >> burning on /dev/scd0 (which is ide-scsi-emulation, in fact >> /dev/hdc), speed=2, at the same time gives a high load, but works >> fine otherwise. > >Uh, what? It stops PPP packet loss? And if you're not burning a CD on >/dev/hdc, PPP drops packets? no, but if ripping from an atapi-cdrom generates lots of interrupts, burning on an atapi-cdr should do so, too. one would think that two interrupt-emitting processes would interfere with each other, as is the case with ripping and a ppp-connection via an asynchronous line. but ripping on one atapi-device and burning on another works just fine. >ATAPI CDROMs really do suck. that´s right, but they´re _cheap_, therefore the only option for some of us... &rw -- -- +++ EUnet/[EMAIL PROTECTED], 15.-17.2.'2k, Ebene02/Stand08 +++ ----- ___ - Robert Waldner EUnet/AT tech staff ---- / / / ___ ____ _/_ -- <[EMAIL PROTECTED]> RW960-RIPE --- /--- / / / / /___/ / --- ---EUnet EDV-DienstleistungsgesmbH--- -- /___ /___/ / / /___ /_ ---- Diefenbachgasse 35 A-1150 Wien - ----- Tel: +43 1 89933 Fax: +43 1 89933 533
