Add an entry about slow starting SCSI CD-ROM:

When I booted my system without the above option, the CDROM could not
respond in time to the bootup probe of devices and was "missed".  When
I tried to access the device I got the "Device not configured" error
message.  I rebuilt the kernel with the SCSI_DELAY option and the
problem went away.

Sometimes a SCSI CD-ROM may be missed because it hadn't enough time
to answer the bus reset. In you have a SCSI CD-ROM please try to
add the following symbol into your kernel configuration file
and recompile.
