# *** THIS IS STILL LOADED BY DEFAULT ***
# SCSI emulation support. This will provide SCSI host adapter emulation
# for IDE ATAPI devices, and will allow you to use a SCSI device driver
# instead of a native ATAPI driver. This is useful if you have an ATAPI
# device for which no native driver has been written (for example, an ATAPI
# PD-CD or CD-RW drive); you can then use this emulation together with an
# appropriate SCSI device driver. Note that this option does NOT allow you
# to attach SCSI devices to a box that doesn't have a SCSI host adapter
# installed. Also, you'll need to exclude your CD-RW from being grabbed by
# the normal ATAPI driver by passing a flag to the kernel at boot time.
# If you're using LILO, add this: append="hdc=ide-scsi"
# Replace "hdc" with the appropriate device name.
