Iīve got a Yamaha 4416S and itīs working like a charm. You wonīt need a UW-controller just for a CD-burner. Even modern 12x burners have a data rate of only 1.8MB/s. If the data is origined by another device on the SCSI-chain, this will doublke the needed rate. So even a FAST-SCSI controller (10 MB/s in synchronous mode) is enough. I personally chose a FAST one, because of my external SCSI-scanner. FAST allows longer cabling than U or UW. So an El Cheapo thing based for example on Symbios 810A chipset (available e.g. from ASUS or LSI Logic) will do the job (mine was about 20$ only). If you also want to apply modern high speed hard disks, things are different, of course. As to IDE: They work, too. But be aware that on one IDE-channel, there can only be one device at a time sending data to the bus. If you have a hard disk on the same channel, chances are that you will face buffer underruns, if you use the disk, when burning. If you can give a single channel to your burner (or maybe added with a drive, which isnīt used during burn time) things should be fine. > Is there anything special I need to do to the 3.2 release > besides the following [recommended in cdrecord 1.8 README.FreeBSD]: > > options "P1003_1B" > options "_KPOSIX_PRIORITY_SCHEDULING" > options "_KPOSIX_VERSION=199309L" I donīt remember anything special, worked out of the box. > Note that I am not planning to upgrade the 3.2 machine in > any major ways because I am about ready to get a new PC and > stick 4.0/4.1 on it.
