Of course, this is a SCSI-only machine, and it's got 32 MB RAM, but then this allows me to run full X11 *and* burn a CD-R simultaneously. Since the CD-R's are _very_ picky when it comes to a low but steady data-flow, this basically proves that the system does not ``freeze'' for more than ~ 1 second or so, otherwise the CD-R would stop accepting data. People usually yell at us when we declare IDE to `crap' somewhere in Usenet... :) -- 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. ;-)
