Yes folks my age is showing. I confirmed with a seagate engineer that
the ATA100 device will operate as designed with a CDROM drive on the
same channel. The CDROM drive however continues to operate at its speed
which depends on the drive. Transfers from CD to Hard Drive are limited
by the CD of course. Apologies to all.

  I believe that this was one of the defects of the original IDE (one
channel, two devices) that was corrected as part of EIDE (two channels,
two devices each).  Around the same time, malers of slow devices such as
CD-ROM drives started putting fast *interfaces* on them so they wouldn't
slow down hard drives, even on old IDE controllers.
