I have been using an ATAPI CD-ROM quite successfully on both 2.1.5 and
2.2-BETA, and am confident it works on the 2.2-RELEASE - I am waiting for
the Walnut Creek CRDOM to become available.

In 2.1.5, the kernel supplied on the boot floppy won't find the CDROM
at boot time in some circumstances, because the probe conflicts with the
IDE probe.  I fixed it in 2.1.5 with a kernel configuration file that said

controller      wdc0    at isa? port "IO_WD1" bio irq 14 vector wdintr
disk            wd0     at wdc0 drive 0
disk            wd1     at wdc0 drive 1

controller      wdc1    at isa? port "IO_WD2" bio irq 15 vector wdintr
# disk          wd2     at wdc1 drive 0
# disk          wd3     at wdc1 drive 1

options         ATAPI           #Enable ATAPI support for IDE bus
options         ATAPI_STATIC    #Don't do it as an LKM
device          wcd0    #IDE CD-ROM
(I have two IDE disks on the first controller, and the CDROM on the
second.)


In 2.2-BETA, the supplied kernel detects the CDROM correctly, but it
takes a while to do so; mayber 30 to 60 seconds.
