Ok -- I think I have it figured it out.

When I changed motherboards, I didn't use the same PCI slots as before,
and that caused a conflict with DANIATAP.FLT and the RSJ drivers. I could
attach the CD-RW, but I couldn't access the CD Rom drive.

I moved a PCI card from Slot 2 to Slot 3, and everything became OK.

Sorry for the confusion about IDE connections. I have two hard drives,
both on the primary IDE connector, one master and one slave.

I have one CD-RW drive always on the secondary IDE connector (first as
slave, now as master -- that didn't seem to make any difference.

The new motherboard has two sets of IDE connectors: Ultra DMA 100, and
regular.

So -- I have the two hard drives on the ULTRA DMA 100 PRIMARY connector,
and I have the CD-RW drive on the the Regular IDE SECONDARY connector.

The Dani driver lets me use one CD-RW drive as either a CD Rom drive or as
a CD Burner (if anyone wants to know the drive parameters I use, let me
know).

Now OS/2 is happy and Windows is happy, and I can even boot from the CD
Rom drive.

I haven't done a thorough testing yet, but I don't anticipate any more
problems. I find this DMA business and IRQ stuff very confusing.

Thanks for all the help.
Sometimes after I post a question, I will wake up in the middle of the
night and think, "Maybe its the PCI slots!" Then I have to wait all day
until I get a chance to play around and see what happens.
