No. In fact nothing on this system is SCSI....

The Debian/Sarge 2.6 kernel thinks that my SATA hard disk is SCSI -- or rather 
it addresses it as a SCSI drive. I noticed this after a recent upgrade from 
2.4 series to 2.6 series kernels....

However, the 2.6 series kernel does not seem to address my standard IDE 
Plextor DVD/CD drive as a SCSI device...
